Core and Fascia Block Shelf Coupling for Flush Wall Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dimension variances in concrete construction blocks lead to accuracy issues when assembling structures, as existing solutions fail to accommodate variations in block thickness and horizontal ledges, resulting in misaligned and non-flush surfaces.
Innovation Solution
A kit comprising core blocks with horizontal shelves and fascia blocks with cut-out sections designed to mount on these shelves, allowing for alignment and interlocking, while accommodating manufacturing differences in block thickness to ensure a flush front face.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If core blocks and fascia blocks are slipped molded to small variations in the horizontal ledge, then a continuous aligned horizontal ledge is constructed, but any variation in the horizontal ledge makes it impossible for the core block and fascia block to couple
Solution Approach 1:
The patent introduces an intermediary component (the shelf with cut-out section and corresponding block) that mediates between the core block and fascia block. This intermediary absorbs the dimensional variations and provides a stable coupling interface, allowing the core and fascia blocks to connect reliably despite manufacturing tolerances in the horizontal ledge.
Solution Approach 2:
The patent changes the geometric parameters of the coupling interface by introducing the shelf structure with specific dimensions (depth, width, and the cut-out section). This parameter change creates a more robust connection that tolerates variations in the horizontal ledge while maintaining the continuous aligned appearance.
2Ease of manufacture
If the thickness of fascia blocks varies, then manufacturing is simplified, but the front face of the wall becomes non-flush
Solution Approach 1:
The shelf structure acts as an intermediary that compensates for variations in fascia block thickness. By providing a standardized mounting surface with the cut-out section, the shelf ensures that the front face remains flush even when the fascia blocks have different thicknesses, thus decoupling the manufacturing tolerance from the final appearance.
Solution Approach 2:
The shelf structure provides beforehand cushioning by pre-accommodating potential thickness variations in the fascia blocks. The design of the shelf with its specific depth and the cut-out section anticipates the dimensional variations and compensates for them in advance, ensuring a flush front face without requiring precise control of fascia block thickness.
3Ease of operation
If traditional block assembly methods are used, then construction is simple, but dimension variances lead to misaligned and non-flush surfaces
Solution Approach 1:
The shelf and cut-out section assembly serves as an intermediary coupling mechanism that maintains alignment accuracy while preserving ease of operation. The interlocking geometry provides self-alignment and prevents misalignment, allowing workers to assemble blocks simply without requiring high precision, as the shelf structure guides and maintains the correct positioning.
Solution Approach 2:
The patent segments the block assembly system into distinct functional components: the core block with shelf, the cut-out section, and the fascia block. This segmentation allows each component to perform its specific function (support, coupling, finishing) independently, making the overall assembly process simpler while maintaining alignment accuracy through the specialized interface design.

AI summary
A kit and system for constructing structures including at least one core block, at least one fascia block that connects to the core block by mounting a shelf that extends from a face of the core block with a cut-out section of a face of the fascia block, such that the face of the core block and the face of the fascia block form a gap therein between.
