Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If double-layer fabric adhesive bonding is used to achieve smooth edges, then edge smoothness is improved, but edge thickness cannot be sufficiently reduced and skin pressure increases

Engineering Contradiction:

Improveedge smoothnessVSAvoidedge thickness

Core Design Contradiction:

ShapeVSLength of moving object

Solution Approach 1:

The edge region is segmented into different functional zones: an overlapping region where inner and outer layers are misaligned to reduce thickness, and a bonding region where layers are connected for structural integrity. This segmentation allows simultaneous optimization of both thickness reduction and edge smoothness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different edge regions are given different properties: the overlapping portion creates a thinner effective edge thickness for reduced skin pressure, while the bonding portion maintains structural strength. The adhesive is strategically applied only in specific bonding regions rather than uniformly across the entire edge.

Inventive Principle:

Principle #3Local quality

2Length of moving object

If inner and outer fabric edges are completely aligned, then edge thickness is minimized, but softness and elasticity deteriorate causing edge lifting

Engineering Contradiction:

Improveedge thicknessVSAvoidedge softness and elasticity

Core Design Contradiction:

Length of moving objectVSStability of the object's composition

Solution Approach 1:

The edge design employs asymmetry through intentional misalignment of inner and outer layer edges in the overlapping region. This asymmetric configuration creates a stepped edge structure that maintains thickness reduction while the layered overlap provides elastic recovery and softness, preventing edge lifting during movement.

Inventive Principle:

Principle #4Asymmetry

3Object-affected harmful factors

If double-layer fabric adhesive bonding is used, then stitching friction is avoided, but adhesive distribution unevenness reduces service life and edge durability

Engineering Contradiction:

Improvefriction between sewing threads and skinVSAvoidadhesive bonding durability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The adhesive bonding is applied locally only in specific bonding regions rather than uniformly across the entire edge. This localized adhesive application ensures even distribution in critical areas while maintaining structural integrity. The misaligned overlapping region provides alternative structural connection points that compensate for adhesive limitations, enhancing overall durability.

Inventive Principle:

Principle #3Local quality

4Manufacturing precision

If complete edge alignment is used, then manufacturing precision is maximized, but skin-contact effect deteriorates due to pressure and friction

Engineering Contradiction:

Improveedge alignment precisionVSAvoidskin pressure and friction

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The edge is divided into overlapping and bonding regions, allowing the overlapping portion to reduce skin contact pressure and friction while the bonding region maintains structural precision. This segmentation enables independent optimization of comfort and manufacturing precision.

Inventive Principle:

Principle #1Segmentation
