Mechanism

Each block presents a defined pattern of side-face cavity ports on its laying-direction faces. A representative pattern places two electrical contacts and two electrolyte channels per major face, arranged so that the contact-to-contact and channel-to-channel mating geometry is preserved when the block is rotated in any of the orientations admitted by standard masonry practice. Each port is a recessed cavity opening to the block face, lined with a chemically resistant sleeve and terminated internally to the block's embedded conductor or electrolyte manifold. The mating face presents the complementary geometry: a pin protruding to a defined standoff, terminated to its own conductor or manifold, with an annular sealing land surrounding the pin.

When the mason places a block onto a freshly laid mortar bed, the protruding pins on the underside or end face of the new block enter the cavity ports on the adjacent block. The pin and cavity are dimensioned with a generous initial clearance (typically 1 to 3 millimeters of radial play) and a tapered lead-in, so that masonry placement tolerance, on the order of plus or minus 5 millimeters in plan and plus or minus 3 millimeters in elevation, does not prevent engagement. As the mason taps the block to its final bed line, the pin progresses into the cavity until the annular sealing land contacts the cavity rim. Continued seating compresses the mortar between the block faces, and the mortar in turn loads the sealing land axially, producing a gasketed interface that resists both electrolyte leakage out of the joint and electrical creepage along the wetted mortar path.

The pin-and-socket geometry serves three simultaneous functions. It self-aligns: the tapered lead-in steers the pin to the cavity centerline, correcting placement error within the engagement clearance. It conducts: the pin and cavity sleeve are formed from corrosion-resistant alloy or plated copper, providing a low-resistance metal-to-metal contact path for electrical ports and a chemically inert flow path for electrolyte ports. It seals: the annular land translates mortar compression into a defined sealing pressure on a controlled contact area, producing a reproducible barrier without requiring the mason to apply or position a separate gasket.

Operating Parameters

The port system operates within the envelope established by ordinary masonry practice. Mortar joint compression during placement is typically 10 to 100 psi at the bed-joint plane, depending on block weight, mortar consistency, and the mason's tapping force; the cured-state retained compression is lower, on the order of 5 to 30 psi as the mortar shrinks and the wall accepts gravity load. The disclosed sealing land is dimensioned so that the lower bound of this range, 10 psi during placement, 5 psi sustained, is sufficient to produce a leakage-tight interface for the intended electrolyte chemistries and a contact resistance below 5 milliohms per port for the intended electrical load.

Electrical ports are rated for direct-current operation at the cell-stack voltage of the block (typically 1.5 to 4 volts per cell, with multi-cell blocks reaching 12 to 48 volts) and currents to several amperes per port, with the four-port-per-face pattern providing redundancy and current sharing. Electrolyte ports admit volumetric flow at the rates required for thermal management or electrolyte refresh, typically below 1 liter per minute per port at differential pressures below 2 psi. The seal is verified after wall completion: the building electrical system performs an automatic discovery sweep, addressing each block by its credentialed identity, and runs a connectivity test that measures port-to-port resistance, leakage current, and where instrumented, electrolyte continuity. Failed ports are localized to the specific block-pair interface and reported to the commissioning agent.

The port pattern is dimensionally stable across the temperature and humidity range encountered during construction (typically 0 to 40 degrees Celsius ambient, with mortar surface temperatures briefly exceeding 50 degrees Celsius during exothermic cure) and across the service envelope of the wall. Differential thermal expansion between the metal port components and the cementitious block body is accommodated by the sleeve liner, which is bonded to the block under controlled conditions during block manufacture rather than at the construction site.

Alternative Embodiments

The disclosed port pattern admits a family of variants. In a first embodiment, the four-port-per-face pattern is reduced to two ports per face for low-current applications, sacrificing redundancy for manufacturing simplicity. In a second embodiment, the pattern is increased to six or eight ports per face for high-current bus applications, with parallel ports providing current capacity and dedicated sense ports providing per-block voltage measurement independent of the load path. In a third embodiment, the electrical and electrolyte ports are physically segregated to opposite faces of the block, eliminating the possibility of cross-contamination between fluid and electrical paths and admitting independent service of the fluid and electrical interconnect networks.

The pin-and-socket polarity may be alternated by face (pins on the bottom and one end face, sockets on the top and the opposite end face) so that any block can mate with any other in any laying-orientation admitted by the bond pattern. Alternatively, all pins may be carried on a separate connector strip that the mason installs into the cavity ports of one block before placing the next, eliminating protruding hardware on the block itself and simplifying handling and stacking. The sealing land may be a flat metallic ring, an elastomeric O-ring captured in a recess, or a deformable metal gasket, each selected to match the electrolyte chemistry and the expected service temperature range.

Composition And Array Formation

The port pattern admits multiple array topologies depending on the mason's placement choices, without requiring different block variants for different topologies. When blocks are laid in a running bond with side faces in continuous contact and aligned polarity, the side-face ports compose into parallel arrays: every block on a course shares a common positive and common negative bus, and inter-course ports stack the courses in further parallel. When blocks are laid with end faces presenting alternating polarity, the end-face ports compose into series strings: each block adds its cell-stack voltage to the running total, and a course of N blocks presents N times the per-block voltage. Mixed series-parallel arrays are formed by combining bond patterns: parallel within a course, series between courses, or any other geometric combination admitted by the bond.

The building electrical system reads the resulting array topology from the credentialed admissibility profiles after installation. Each block's profile records its terminal assignments and its position in the wall coordinate system, established during placement by an embedded localization primitive; the system constructs the connectivity graph by composing the per-block profiles through the port pattern. The mason therefore designs the electrical topology by designing the bond pattern, using ordinary masonry skill, while the electrical system handles topology discovery, addressing, and balancing without intervention from the trade. Composition with the credentialed-materials surfaces ensures that the discovered topology is admitted only when each participating block presents valid water-coupled, thermal, and electrochemical envelopes.

Prior Art And Distinctions

Prior modular electrical-construction systems have used standoff connectors, plug-in busbars, or post-installation cabling to connect block-scale electrical assemblies. These approaches require either dedicated electrical labor distinct from the masonry trade, or specialized non-masonry block geometries that depart from standard wall-construction practice. Prior fluidic interconnects in masonry, for example, hydronic radiant-wall systems, have used external piping with sealed penetrations, again requiring a separate trade. Prior battery-construction systems have relied on factory-assembled modules with welded or fastened terminals, which do not admit field assembly into wall-scale arrays.

The disclosed side-face cavity port differs in that it is sealed and seated by the same mortar-placement action that lays the wall, requires no secondary sealing or fastening operation, accepts the placement tolerance of ordinary masonry practice without electrical or fluidic compromise, and is verified by automatic discovery rather than by manual inspection. The combination of self-alignment under mason-scale tolerance, sealing under mortar joint compression alone, and electrical-system verification through credentialed discovery is the inventive contribution. Variants that achieve any one of these without the others, for example, a self-aligning connector that requires a secondary clamping operation, or a mortar-sealed connector that requires manual continuity testing, fall outside the disclosed combination.

Disclosure Scope

This disclosure forms part of Provisional Application 64/050,895 and discloses side-face cavity ports as one element of the modular-substrate-block primitive family. The scope extends to any block-to-block interconnect that combines pin-and-socket self-alignment within ordinary masonry placement tolerance, sealing through mortar-joint compression in the disclosed pressure range, and post-assembly verification through automatic discovery against credentialed admissibility profiles. Variants that substitute alternative port counts, alternative sealing-land geometries, alternative pin-and-socket materials selected for compatibility with the chosen electrolyte chemistry, or alternative array bond patterns admitted by standard masonry practice are within the disclosed scope, provided they preserve the three-function combination of self-alignment, compression sealing, and credentialed verification.
