Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If existing fabric manufacturing methods are used, then production time and costs are controlled, but the cool feeling function does not last long
Solution Approach 1:
The fabric is divided into two distinct layers: an outer layer made of hygroscopic yarn materials for moisture absorption and an inner layer made of thermally conductive yarn materials for heat dissipation. This segmentation allows each layer to specialize in its function, thereby extending the duration of the cool feeling effect while maintaining efficient production through standardized manufacturing processes for each layer type
Solution Approach 2:
The fabric combines two different material systems (hygroscopic materials and thermally conductive materials) into a single composite structure. This composite approach enables the fabric to maintain prolonged cool feeling by simultaneously performing moisture absorption and thermal conduction, while the production time remains controlled through established composite fabric manufacturing techniques
2Reliability
If existing fabric manufacturing methods are used, then production costs are contained, but the cool feeling function is not sufficient
Solution Approach 1:
By segmenting the fabric into functional layers (outer hygroscopic layer and inner thermally conductive layer), the design achieves reliable cool feeling effectiveness through specialized material functions. The manufacturing complexity is managed by treating each layer as a separate component that can be produced using standard textile processes before being assembled into the final composite fabric
Solution Approach 2:
The composite structure combining hygroscopic and thermally conductive materials delivers superior and reliable cool feeling effectiveness. The manufacturing process leverages existing composite fabric production methods, maintaining ease of manufacture while achieving enhanced functional performance through the synergistic combination of materials
3Productivity
If existing fabric manufacturing methods are used, then production time is controlled, but production complexity increases
Solution Approach 1:
The manufacturing process is segmented into distinct stages: producing outer layer fabric from hygroscopic yarns, producing inner layer fabric from thermally conductive yarns, and assembling them together. This segmentation improves productivity by allowing parallel production of layers while keeping the overall process complexity manageable through standardized assembly procedures
Solution Approach 2:
The production of composite fabric with cool feeling functions achieves improved productivity by utilizing established composite material manufacturing techniques. The process complexity is controlled by applying conventional composite fabric production methods, where layers are manufactured separately and then combined using standard industrial textile assembly processes
