Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a sensor is integrated into the tool magazine system for direct post-processing measurement, then measurement efficiency is improved and workload is reduced, but power supply and data transmission become difficult without cable connections
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The sensor transmits measurement data wirelessly to the external device, eliminating the need for physical cable connections while maintaining data transmission functionality. This substitution resolves the contradiction by enabling sensor integration without the complexity of cable management.
Solution Approach 2:
The sensor is designed to be self-powered through a built-in power supply unit that can be recharged when the sensor is stored in the tool magazine. This self-service power supply mechanism eliminates the need for external cable connections for power supply, allowing the sensor to operate independently while integrated in the tool magazine system.
2Reliability
If a cable connection is used to supply power and transmit data to the sensor, then power supply and data transmission are reliable, but the device complexity increases and the sensor cannot be easily integrated into the automatic tool changing system
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The sensor transmits measurement data wirelessly to the external device, eliminating the need for physical cable connections while maintaining data transmission functionality. This substitution resolves the contradiction by enabling sensor integration without the complexity of cable management.
Solution Approach 2:
The sensor is designed with a universal interface that allows it to be treated and handled like other tools in the tool magazine. It can be automatically changed along with tools, and its power supply and data transmission functions are integrated into its design, making it universally compatible with the automatic tool changing system without requiring special cable connections.
3Adaptability or versatility
If the sensor is treated as a tool and placed in the tool magazine, then automatic tool changing can replace the sensor with tools, but cable-free power supply and data reception become difficult
Solution Approach 1:
The sensor is designed to be self-powered through a built-in power supply unit that can be recharged when the sensor is stored in the tool magazine. This self-service power supply mechanism eliminates the need for external cable connections for power supply, allowing the sensor to operate independently while integrated in the tool magazine system.
Solution Approach 2:
The patent replaces the mechanical cable connection system with a wireless communication system. The sensor transmits measurement data wirelessly to the external device, eliminating the need for physical cable connections while maintaining data transmission functionality. This substitution resolves the contradiction by enabling sensor integration without the complexity of cable management.

AI summary
Provided is a three-dimensional measurement device applicable to a machining machine. A sensor head contains a body and a collet chuck. A light emitting window and a light receiving window are provided on the front end of the body. A non-contact sensor is incorporated in the body. Laser light emitted by the non-contact sensor is radiated onto a workpiece through the light emitting window. Laser light reflected from the surface of the workpiece is received by the light receiving window. A collet chuck is attached to the rear end of the body. The collet chuck has the same shape as a collet chuck provided by each tool housed in a tool magazine of a machining center.
