Engineering Contradiction Analysis
1Reliability
If conductive wires are disposed on flexible objects using conventional methods, then the manufacturing process is simple, but the reliability and lifespan of the conductive wires vary due to differing mechanical properties of the layout area
Solution Approach 1:
The patent applies local quality by dividing the flexible object into multiple layout areas with different mechanical properties (strain/stress characteristics). Each area is assigned specific wire routing parameters from the layout database based on its local mechanical characteristics, enabling the conductive wire layout to be optimized locally for each area's specific conditions rather than using a uniform approach across the entire flexible object.
Solution Approach 2:
The patent implements preliminary action by pre-establishing a layout database that contains wire routing information corresponding to different strain/stress conditions before the actual manufacturing process. This database is created in advance based on the mechanical properties of various layout areas, allowing the system to quickly retrieve and apply appropriate routing parameters during production without performing complex real-time calculations.
2Reliability
If wire routing is optimized according to strain/stress distribution, then the reliability of conductive wires is enhanced, but the manufacturing process complexity increases
Solution Approach 1:
The layout database is established in advance, containing pre-calculated wire routing information for different strain/stress conditions. This preliminary preparation eliminates the need for complex real-time optimization during manufacturing, as the system simply retrieves appropriate routing parameters from the pre-prepared database based on detected mechanical properties.
Solution Approach 2:
The layout database serves as an intermediary between the mechanical property detection and the wire routing manufacturing process. It translates complex strain/stress distribution data into simplified wire routing parameters, acting as a mediator that bridges the gap between theoretical optimization and practical manufacturing execution.
3Manufacturing precision
If a layout database is established to store wire routing information, then the wire placement accuracy is improved, but the data management complexity increases
Solution Approach 1:
The layout database is established in advance with all necessary wire routing information organized according to different strain/stress conditions. This pre-organization of data ensures that during manufacturing, the system only needs to retrieve appropriate entries based on detected mechanical properties, rather than performing complex real-time data processing or calculations.
