Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conductive gel is used, then good conductive performance is achieved, but high viscosity makes it unsuitable for spray coating
Solution Approach 1:
The patent changes the physical and chemical parameters of the conductive gel by replacing traditional resin matrices with a water-based system containing carbomer and glycerin. This parameter change reduces viscosity to enable sprayability while maintaining conductive performance through optimized concentrations of conductive particles and binding agents.
Solution Approach 2:
The patent creates a composite material system combining water, carbomer, glycerin, conductive particles (silver, aluminum, or graphite), and binding agents. This composite approach achieves both low viscosity for sprayability and sufficient conductivity by carefully selecting and proportioning each component's contribution to the overall properties.
2Reliability
If traditional resin-based conductive gel is used, then stable conductivity is achieved, but high viscosity limits application methods
Solution Approach 1:
The patent fundamentally changes the base material parameter from organic resin to water-based carbomer gel, enabling new application methods including spray coating, brushing, and rolling. The conductivity stability is maintained through optimized particle concentration and distribution within the water-based matrix.
Solution Approach 2:
By reducing viscosity through the water-based formulation, the patent enables hydraulic application methods such as spray coating where the conductive agent is delivered as a雾化 liquid. This expands manufacturing flexibility beyond traditional dispensing methods required for high-viscosity gels.
3Reliability
If conductive particles are separated in the gel, then good conductivity is achieved after solidification, but high viscosity prevents uniform distribution
Solution Approach 1:
The patent changes the viscosity parameter through water-based formulation, enabling uniform particle distribution during application. The low-viscosity medium allows conductive particles to disperse evenly throughout the gel matrix before drying, ensuring consistent conductivity after solidification.
Solution Approach 2:
The water-based carbomer gel creates a homogeneous medium that uniformly distributes conductive particles during application. The low viscosity ensures consistent particle spacing and prevents aggregation, leading to uniform conductive properties across the entire applied area after drying.

The conductive agent can be efficiently sprayed onto fabrics or articles, forming a conductive portion with optimal viscosity and conductivity, facilitating applications such as electrotherapy and providing a more convenient and efficient method compared to traditional conductive gel applications.
Implementation Method 1
forming a conductive path through mutual contact between conductive particles
Implementation Method 2
when the thickness of the isolation layer between adjacent conductive particles in a conductive gel become small enough, the free electrons of the conductive particles can pass through the isolation layer (i.e., through the potential barrier)
