Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are used for power supply and signal transmission to the intelligent monitoring module on the motion member, then the module can be operated and monitored in real-time, but the wires increase the overall volume and are subjected to pulling forces during motion
Solution Approach 1:
The patent extracts the harmful element (wires) from the system by implementing wireless power transmission through electromagnetic induction. The transmitting coil is fixed on the linear rail while the receiving coil is mounted on the motion member, eliminating the need for physical wire connections and thereby removing the source of pulling forces and volume increase.
Solution Approach 2:
The patent replaces the mechanical wire connection system with an electromagnetic field-based wireless power transmission system. This substitution eliminates the mechanical constraints and physical connections that cause volume increase and pulling forces on wires during motion.
2Reliability
If wire chains are used for wire protection, then the wires are protected during motion, but this results in a significant increase in the overall volume and causes more pulling force on the wires
Solution Approach 1:
The patent removes the wire chains and protective elements entirely by implementing wireless power transmission. Without physical wire connections, there is no need for protective chains, thereby eliminating the associated volume increase and pulling forces.
Solution Approach 2:
The mechanical wire protection system (wire chains) is replaced by an electromagnetic field-based wireless power transmission system, eliminating the need for physical protection mechanisms and their associated forces.
