Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a multi-layered foldable tent is formed with singular modules organized in columns and rows with double layer in odd rows and single layer in even rows, then the structure can be assembled in a predetermined geometrical pattern, but the structural composition and geometrical configuration are not viable structurally under static and dynamic load conditions
Solution Approach 1:
The patent applies asymmetry by horizontally offsetting unit cells in alternating rows. Specifically, unit cells in odd-numbered rows are offset in the x-direction relative to unit cells in even-numbered rows, creating an interlocking staggered configuration. This asymmetric arrangement distributes loads more effectively across the structure and prevents the structural instability that occurred with the previous symmetric alignment, while maintaining the modular assembly capability.
2Stability of the object's composition
If slender structural support elements are connected by anchoring members to form a skeleton with integrated fabric, then the structure achieves stability under static and dynamic loads, but the device complexity increases with multiple layers, anchoring members, and joints
Solution Approach 1:
The patent applies segmentation by dividing the structure into repeating unit cells that each contain slender structural support elements and anchoring members. These modular unit cells can be independently assembled and then connected to form the complete multi-layered structure. This segmentation reduces overall complexity by creating standardized, repeatable modules rather than requiring custom design for each structural element.
Solution Approach 2:
The patent applies universality through the integration of fabric within the structural skeleton. The fabric serves multiple functions: it provides structural stability when integrated with the slender support elements and anchoring members, and it can accommodate functional elements like ducting. This multi-functionality reduces the need for separate components, thereby managing complexity while achieving structural stability.
3Stability of the object's composition
If unit cells are horizontally offset in alternating layers, then structural stability is improved through better load distribution, but the manufacturing precision requirements increase to ensure proper alignment and connection
Solution Approach 1:
The patent applies preliminary action by incorporating features in the unit cell design that facilitate proper alignment during assembly. The slender structural support elements and anchoring members are configured with predetermined geometries that guide correct positioning of offset unit cells. This preliminary design of alignment features reduces the actual manufacturing precision requirements during assembly, as the components self-align through their inherent geometric constraints.
