Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If heat transfer is applied to performance fabrics, then decorative components can be added to fabrics, but the fabric is susceptible to damage during heat application
Solution Approach 1:
A polyol-based compatibility layer is introduced as an intermediary between the silicone-based heat transfer ink and the performance fabric substrate. This compatibility layer has molecular structure characteristics that enable it to bond with both the silicone ink and the performance fabric, facilitating heat transfer application while protecting the fabric from direct heat exposure and damage.
2Strength
If silicone-based heat transfer ink is used, then adhesion to fabric can be improved, but the curing process may be degraded by water-based inks
Solution Approach 1:
The polyol-based compatibility layer serves as a protective intermediary that allows water-based inks to interface with the silicone-based heat transfer ink without degrading the curing process. The compatibility layer's molecular structure enables it to be compatible with both water-based and silicone-based materials, maintaining adhesion strength while preserving the reliability of the curing process.
3Duration of action of stationary object
If adhesion methods are improved for performance fabrics, then heat transfer durability can be enhanced, but the curing process of silicone-based inks may be degraded
Solution Approach 1:
The polyol-based compatibility layer acts as a mediator that enables improved adhesion to performance fabrics while protecting the silicone-based ink curing process. By positioning this compatibility layer between the heat transfer ink and the fabric, the system achieves durable heat transfer application without compromising the chemical curing process of the silicone components.
