Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If adhesives are used to join electrical conductors, then mechanical bonding is provided, but internal resistance increases and performance degrades
Solution Approach 1:
The patent uses a binder material as an intermediary substance between the conductive element and the foil, which provides both mechanical bonding and maintains electrical conductivity. The binder is specifically formulated to be conductive, bridging the gap between mechanical attachment requirements and electrical performance requirements.
Solution Approach 2:
The patent employs composite materials consisting of conductive fillers (such as metal powders or carbon materials) embedded in a binder matrix. This composite structure combines the mechanical properties of the binder with the electrical conductivity of the filler, achieving both mechanical strength and low electrical resistance simultaneously.
2Reliability
If solder connections are used to increase contact area, then electrical conductivity improves, but intermetallic compound formation occurs leading to brittleness and resistance increase
Solution Approach 1:
The patent extracts or eliminates the soldering process entirely from the joining method. Instead of using solder that forms intermetallic compounds, the invention uses a binder-based system that achieves both mechanical and electrical functions without the harmful chemical reactions associated with soldering.
Solution Approach 2:
The patent employs a binder material that can be applied and cured in place, replacing the need for solder that requires complex metallurgical processes. The binder system is simpler, more controllable, and avoids the long-term degradation issues of intermetallic formation.
3Strength
If mechanical means like crimping are used to join conductors, then mechanical strength is provided, but contact resistance increases due to limited atomic contact spots
Solution Approach 1:
The patent merges the mechanical bonding function and the electrical conduction function into a single integrated binder layer. This eliminates the need for separate mechanical attachment (like crimping) that would create limited contact spots, as the binder provides continuous contact across the entire interface between conductive elements.
