Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a circuit carrier with an electrical metal core is used for the electrical circuit, then the electrical circuit can be implemented, but the circuit carrier takes up a lot of space in the rolling bearing
Solution Approach 1:
The patent extracts and eliminates the separate circuit carrier component from the rolling bearing system. Instead of using a traditional circuit carrier with metal core, the invention integrates the electrical circuit directly onto the rolling bearing surface through coating layers, removing the bulky carrier structure while maintaining electrical circuit functionality
Solution Approach 2:
The patent merges the electrical circuit with the rolling bearing itself by applying insulating and conductive coating layers directly onto the bearing surface. This integration combines the bearing function with the electrical circuit function into a single unified structure, eliminating the need for separate circuit carrier components
2Volume of moving object
If the electrical circuit is integrated directly on the rolling bearing surface, then installation space is minimized, but the electrical components need protection from environmental influences
Solution Approach 1:
The patent uses thin film coating layers (insulating layers and conductive layers) applied directly onto the rolling bearing surface to create the electrical circuit. These thin films provide both the electrical functionality and environmental protection, serving as a compact barrier against moisture, particles, and other environmental factors while maintaining minimal installation space
Solution Approach 2:
The patent employs composite material structures consisting of multiple coating layers (insulating layers and conductive layers) with different functional properties. The insulating layers provide environmental protection and electrical isolation, while the conductive layers provide electrical conductivity for the circuit traces, creating a multi-functional composite structure that addresses both space constraints and environmental protection requirements
