Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wired power supply is used to supply power to the sensor, then the sensor can receive power, but the wiring may be entangled with the turret during rotation, hindering the rotation
Solution Approach 1:
The patent replaces the mechanical wired power supply system with a wireless power transmission system using electromagnetic fields. The power transmitting coil in the turret and power receiving coil in the turning tool enable non-contact power transfer, eliminating the need for physical wiring that would entangle during turret rotation.
2Use of energy by moving object
If electric contact is used to supply power, then power can be transmitted, but it is difficult to ensure high waterproofness when using coolant liquids
Solution Approach 1:
The patent substitutes the electric contact-based power transmission system with a non-contact wireless power transmission system using electromagnetic induction. This eliminates the need for waterproof electric contacts, as power is transmitted through electromagnetic fields between the power transmitting coil and power receiving coil without physical contact points that would require waterproofing.
3Ease of operation
If non-contact power transmission is used, then turret rotation is not hindered and waterproofness is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent integrates multiple functions into the existing turning tool structure. The power receiving coil is incorporated into the turning tool body, and the sensor detects operational data while being powered wirelessly. This multi-functional integration minimizes additional components while achieving wireless power transmission and data collection.
