Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Ethernet twisted pair cables are used for communication in trunking lighting systems, then communication functionality is achieved, but the system becomes inflexible and laborious to handle when changing device locations
Solution Approach 1:
The communication cable is segmented into multiple discrete contact points along the trunking profile, allowing individual sections to be activated independently. This enables flexible device placement at any increment along the profile without requiring manual cable cutting and crimping, as the cable remains intact with selective contact activation.
Solution Approach 2:
The communication cable contacts are pre-positioned and exposed at defined discrete increments along the trunking profile during manufacturing. This preliminary arrangement eliminates the need for on-site cable modification when installing devices, as all necessary contact points are already in place and ready for connection.
2Adaptability or versatility
If multiple Ethernet cables are installed to connect multiple devices, then all devices can communicate, but spatial handling becomes difficult within a single trunking profile
Solution Approach 1:
Multiple communication cable contacts are merged into a single integrated trunking profile structure. Instead of installing separate cables for each device, all communication contacts are embedded within the same profile, allowing multiple devices to be connected spatially organized and managed within a single enclosure, thereby reducing overall system complexity.
3Length of moving object
If manual cutting and crimping of Ethernet cables is performed to shorten cables, then cable length is adjusted, but the process becomes laborious and time-consuming
Solution Approach 1:
The communication cable is pre-configured with exposed contacts at defined discrete increments along the entire length of the trunking profile during manufacturing. This preliminary preparation eliminates the need for on-site cable cutting, crimping, and termination, as the cable is already configured to provide appropriate length and contact points for any device placement.
4Adaptability or versatility
If powerline communication is used as an alternative to Ethernet, then communication is achieved without Ethernet cables, but expensive dedicated equipment is required and electromagnetic compatibility issues arise
Solution Approach 1:
The patent uses Ethernet twisted pair cables as an intermediary medium for communication within the trunking lighting system. This intermediary approach provides stable electromagnetic performance and avoids the EMI issues associated with powerline communication, while still achieving the goal of flexible device connectivity without requiring expensive dedicated powerline equipment.
