Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorbers in shoe soles, such as those made of resin or rubber, lack structural enhancements for improved shock absorption, and existing lattice structures do not fully optimize shear deformation for enhanced shock absorption.
Innovation Solution
A shock absorber with a columnar shape featuring non-intersecting ridgelines defining polygonal end surfaces and connection surfaces, allowing for increased shear deformation and enhanced shock absorption, which can be made of resin or rubber and optionally foam materials, with chamfered or curved surfaces for smoother transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional resin or rubber shock absorbers are used in shoe soles, then basic shock absorption is provided, but structural enhancement for improved shock absorption is lacking
Solution Approach 1:
The shock absorber is divided into multiple connection surfaces (first, second, third, and fourth connection surfaces) with distinct ridgelines, creating a segmented geometric structure that distributes and enhances shock absorption across different facets while maintaining overall structural integrity
Solution Approach 2:
The shock absorber employs asymmetric polygonal end surfaces where the first end surface has N vertices and the second end surface has M vertices (M > N), creating an asymmetric geometric configuration that optimizes shear deformation patterns for enhanced shock absorption performance
2Reliability
If existing lattice structures are used to enhance shock absorption, then some structural improvement is achieved, but shear deformation optimization is insufficient
Solution Approach 1:
The ridgelines connecting the polygonal end surfaces are configured as curved surfaces rather than straight lines, creating smooth transitions between facets that optimize stress distribution and enhance shear deformation characteristics for improved shock absorption
Solution Approach 2:
The shock absorber transitions from conventional two-dimensional lattice patterns to a three-dimensional polyhedral structure with multiple angled connection surfaces and ridgelines, adding spatial dimensionality that maximizes shear deformation capacity and shock absorption efficiency
3Reliability
If the shock absorber structure is made more complex to increase shear deformation, then shock absorption improves, but the structure becomes more complicated
Solution Approach 1:
Multiple connection surfaces and ridgelines are nested within a single columnar shock absorber body, with each connection surface containing specific ridgelines that are hierarchically organized to maximize shear deformation while maintaining a compact integrated structure
Solution Approach 2:
Different connection surfaces are assigned specific ridgeline configurations tailored to their local geometric requirements, with each surface optimized for its particular orientation and function while contributing to the overall shock absorption system
