Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional honeycomb structure is used, then high strength-to-weight ratio is achieved, but shape memory capability is lost and shock/vibration absorption is inadequate
Solution Approach 1:
The structure is divided into multiple unit cells, each containing bowling pin structures with specific geometries. This segmentation allows the overall structure to maintain high strength-to-weight ratio while individual cells provide shape memory capability through their unique geometries and material properties
Solution Approach 2:
The patent employs composite material structures combining different geometric configurations (bowling pin structures with 3D S-shaped sidewalls) within the honeycomb framework. This composite approach enables simultaneous achievement of high strength-to-weight ratio and shape memory capability that neither simple honeycomb nor single-geometry structures can provide alone
2Device complexity
If conventional honeycomb structure is used, then structural simplicity is maintained, but shock absorption and vibration reduction characteristics are inadequate
Solution Approach 1:
The bowling pin structures incorporate 3D S-shaped sidewalls that dynamically respond to applied loads. The curved geometry allows the structure to adaptively deform and absorb shock energy while maintaining structural integrity, providing superior shock and vibration absorption compared to straight-walled honeycomb structures
Solution Approach 2:
The patent utilizes curved 3D S-shaped sidewalls in the bowling pin structures instead of straight lines. This curvature enables the structure to better distribute and absorb impact forces, improving shock and vibration characteristics while maintaining relative structural simplicity through the repeating unit cell pattern
3Reliability
If interlocked bowling pin structures with 3D S-shaped sidewalls are implemented, then shock absorption and shape memory are improved, but manufacturing complexity increases
Solution Approach 1:
The complex geometry is segmented into repeating unit cells with standardized bowling pin structures. This modular approach allows the complex 3D S-shaped sidewalls to be manufactured as identical repeating units, reducing overall manufacturing complexity through standardization and repetition
Solution Approach 2:
The bowling pin structures are nested within the honeycomb framework, with each unit cell containing the specialized geometry. This nesting approach allows the complex shock-absorbing structures to be integrated within the simpler honeycomb envelope, managing manufacturing complexity by organizing complexity at the unit cell level rather than the overall structure level

AI summary
The disclosure is directed to a single layer including a plurality of unit cells. Each unit cell includes a first bowling pin structure interlocked with a second bowling pin structure arranged in an opposite orientation to the first bowling pin structure. The first bowling pin structure has a first sidewall, a first wide end, and an opposing first narrow or equal size end. Likewise, the second bowling pin structure has a second sidewall, a second wide end. Each of the bowling pin structures has a center axis along a longitudinal axis of the single layer structure. The first and second sidewalls are configured to have a 3D “S” shape along the longitudinal or vertical axis such that each of the first wide end and the second wide end has a convex shape and each of the first narrow or equal size end and the second narrow or equal size end has a concave shape.
