Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool holders with integrated sensors face challenges in instrumentation and maintenance due to electrical connections, particularly when mounted in rotating turrets or spindles, leading to mechanical strain and potential failures from vibrations, which compromise the reliability of the battery and printed circuit board.
Innovation Solution
The tool support design mechanically isolates the battery from the printed circuit board by placing it remotely and using a seal and elastic material to dampen vibrations, ensuring robustness and protection against environmental factors like dust and oil.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery is installed on the printed circuit board for compactness, then the device size is reduced, but the vibrations cause mechanical strain leading to connection breakage and potential failures
Solution Approach 1:
The device is divided into two separate modules: a battery housing containing the battery and a printed circuit board housing containing the electronics. This segmentation isolates the heavy battery from the delicate circuit board, preventing vibration-induced mechanical strain on connections while maintaining a compact overall device structure through modular design.
Solution Approach 2:
A mechanical coupling mechanism with vibration-dampening features serves as an intermediary between the battery housing and printed circuit board housing. This intermediary component absorbs and isolates vibrations, protecting the electrical connections from mechanical strain while maintaining structural integrity and compactness.
2Volume of moving object
If the battery is placed close to the printed circuit board, then the device is more compact, but the mass difference causes severe mechanical strain under repeated vibrations
Solution Approach 1:
The device is divided into two separate modules: a battery housing containing the battery and a printed circuit board housing containing the electronics. This segmentation isolates the heavy battery from the delicate circuit board, preventing vibration-induced mechanical strain on connections while maintaining a compact overall device structure through modular design.
Solution Approach 2:
A mechanical coupling mechanism with vibration-dampening features serves as an intermediary between the battery housing and printed circuit board housing. This intermediary component absorbs and isolates vibrations, protecting the electrical connections from mechanical strain while maintaining structural integrity and compactness.
3Measurement precision
If the tool holder is equipped with sensors and wireless transmission means, then the monitoring capability is improved, but the instrumentation and maintenance become more difficult due to electrical connections
Solution Approach 1:
The tool holder is designed as a modular system with separable components including the battery housing, printed circuit board housing, and cutting tool assembly. This segmentation allows sensors and wireless transmission means to be easily accessed and replaced by simply detaching the relevant module, significantly improving maintenance ease while preserving full monitoring functionality.

AI summary
A tool post of a machine tool, in which the tool post is capable of receiving a cutting insert for machining a component, is provided. The tool post includes at least one sensor capable of determining a parameter representative of a cutting action between a component to be machined and a cutting insert; and a support housing which is electrically connected to the sensor and includes a battery and a printed circuit board supplied with current by the battery. The printed circuit board supports, at least partially, a radio transmission unit. The housing includes a base and a cover which can be detached from one another. The battery is supported by the cover and the printed circuit board by the base or vice versa.
