Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If hard metal electrode portion is used, then electrical conductivity and structural strength are improved, but pressure on biological tissue increases causing discomfort
Solution Approach 1:
The electrode portion is constructed from a flexible conductive fabric instead of hard metal, allowing it to conform to biological tissue surfaces without applying excessive pressure. The fabric structure provides both electrical conductivity and mechanical flexibility, resolving the contradiction between structural strength and tissue comfort.
Solution Approach 2:
The electrode assembly combines multiple materials including conductive fabric, insulating coating, and support structures to create a composite system that maintains electrical functionality while reducing mechanical pressure on tissues.
2Stability of the object's composition
If hard metal electrode portion is used, then structural stability is improved, but flexibility and comfort on biological tissue deteriorate
Solution Approach 1:
The conductive fabric electrode portion provides flexibility to adapt to moving biological tissues while maintaining stable electrical contact. The fabric structure can deform with tissue movement rather than maintaining rigid geometry, ensuring both structural stability for signal transmission and flexibility for comfort.
Solution Approach 2:
The electrode design transitions from a static rigid structure to a dynamic flexible fabric structure that can adapt its shape and conformality to match the underlying biological tissue, maintaining stable electrical properties while accommodating physiological movements.
3Object-affected harmful factors
If conductive fabric is used instead of hard metal, then pressure on biological tissue is reduced, but manufacturing complexity increases
Solution Approach 1:
The invention changes the physical parameters of the electrode material from rigid metal to flexible fabric, which fundamentally alters the manufacturing approach. The conductive fabric can be manufactured using textile techniques, coating processes, or woven structures with conductive threads, which are well-established industrial processes that manage complexity effectively.
