Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive electrical wiring is used to connect electrical devices in aircraft interiors, then reliable electrical signal transfer is achieved, but weight increases and fuel efficiency decreases
Solution Approach 1:
The patent merges the electrical wiring function with the composite panel structure itself. The conductive layer is integrated directly into the panel, eliminating separate wiring harnesses and connecting elements. This combining of functions reduces the total weight while maintaining electrical signal transfer capability between devices mounted on the panel.
2Adaptability or versatility
If extensive electrical wiring and routing infrastructure are used, then electrical devices can be connected, but device complexity and installation time increase
Solution Approach 1:
The composite panel with integrated conductive layer serves multiple functions simultaneously: it provides structural support, acts as the electrical connection medium, and serves as the mounting surface for electrical devices. This multi-functionality eliminates the need for separate wiring infrastructure, reducing complexity while maintaining connectivity capabilities.
3Use of energy by moving object
If wiring is routed to each electrical device, then power and data signals are delivered, but manufacturing time and labor intensity increase
Solution Approach 1:
The conductive pathways are pre-integrated into the composite panel during its manufacturing process, before electrical devices are installed. This preliminary action of embedding the electrical infrastructure within the panel structure eliminates time-consuming on-site wiring operations, significantly improving manufacturing efficiency while ensuring proper electrical signal delivery to all devices.
