Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired sensing apparatus is used, then the sensing system can transmit data through physical connections, but the wiring arrangement causes installation difficulties, wiring interference, and reduced sensing accuracy
Solution Approach 1:
The patent replaces the mechanical wiring system with a wireless communication system. The sensing module uses wireless transmission (such as radio frequency or Bluetooth) to send data to the control unit, eliminating physical wire connections. This substitution resolves the contradiction by removing wiring-related installation difficulties and interference while maintaining reliable data transmission for accurate sensing.
Solution Approach 2:
The patent extracts the transmission medium (wires) from the sensing system by implementing wireless communication. The sensing module is designed to transmit data without physical connections, effectively removing the harmful wiring arrangement that caused installation difficulties and sensing interference, thereby improving both installation convenience and sensing accuracy simultaneously.
2Measurement precision
If the sensing apparatus is positioned close to the feed screw or moving mechanism, then the sensing accuracy improves, but the wiring arrangement limits installation location and causes wire abrasion and breakage
Solution Approach 1:
The patent replaces the mechanical wire connection with wireless transmission, allowing the sensing module to be positioned optimally close to the feed screw or moving mechanism for maximum sensing accuracy without the risk of wire abrasion or breakage. The wireless communication enables the sensor to be placed in the most favorable location for measurement while eliminating the mechanical constraints and reliability issues associated with wired connections.
3Loss of information
If wiring is configured on rotary mechanisms such as tool holders, then data transmission is achieved, but the wiring is difficult to configure and prone to abrasion and breakage
Solution Approach 1:
The patent replaces the complex wiring system on rotary mechanisms with wireless transmission. The sensing module on the tool holder or rotary mechanism communicates data wirelessly to the control unit, eliminating the need to configure wires on rotating parts. This resolves the contradiction by enabling straightforward data transmission without the complexity of rotary wiring configurations and their associated reliability issues.

AI summary
An apparatus for detecting manufacturing parameters of a machine tool is provided, which comprises at least a sensing and transmitting module, and a receiving module. The sensing and transmitting module has a sensor and a wireless transmitting module. The sensor generates a sensing signal with respect to processing parameter of the machine tool. The wireless transmitting module converts the sensing signal into a wireless signal and transmits the wireless signal to the receiving module. Then the wireless signal is decoded and sent to a processing unit for compensating the machine tool. In the present invention, it is not necessary to consider wiring arrangement so that the sensors can be disposed at positions that are close to the mechanism whose operating status could affect the machining process and the compensation, generated according to the foregoing sensing data, for machine tool will be more effective to improve the machining accuracy.
