Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual production with individual copper adhesive tape and soldering is used for each functional zone, then contact robustness can be achieved, but manufacturing time and cost increase significantly
Solution Approach 1:
The patent merges multiple individual contact operations into a single integrated conductor carrier that contacts all functional zones simultaneously. The conductor carrier with multiple contact areas replaces the need for separate copper adhesive tapes and soldering operations for each functional zone, achieving both robust contact and high-speed automated manufacturing.
Solution Approach 2:
The conductor carrier is pre-fabricated with multiple contact areas in the correct positions before assembly. This preliminary preparation allows all contact points to be established in a single operation during panel assembly, eliminating the need for sequential manual contact operations and enabling automated production while maintaining contact reliability.
2Manufacturing precision
If manual production processes are used for contacting functional zones, then contact precision can be achieved, but manufacturing complexity and cost increase
Solution Approach 1:
The conductor carrier integrates multiple contact areas into a single component structure, reducing manufacturing complexity by eliminating the need for separate handling and positioning of multiple individual contact elements. The unified structure maintains precise contact alignment while simplifying the overall manufacturing process for automated production.
3Ease of manufacture
If bonded contact tabs are used for each functional zone, then individual zone contact is achieved, but contact robustness decreases due to tearing
Solution Approach 1:
The conductor carrier combines multiple contact areas into a single rigid structure that distributes mechanical stress across all contact points simultaneously. This eliminates the vulnerability of individual bonded tabs that can tear, as the distributed contact structure prevents localized stress concentration while maintaining ease of application through single-step installation.
