A tool holder system with an intermediate piece extending laterally along the tool carrier and base carrier plates, allowing for adjustable positioning and extension to accommodate various cutting tools, including elongated ones, with a compact and rigid design featuring an adjustable guide and countersunk screw head for height correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the intermediate piece is extended laterally along the tool carrier plate and base carrier plate to accommodate various cutting tools, then the adaptability and versatility of the tool holder system is improved, but the device complexity increases due to the need for different intermediate piece designs
Solution Approach 1:
The intermediate piece is designed with a universal structure that can accommodate different cutting tools through standardized interfaces and adjustment mechanisms. The guide structure with guide teeth and guide grooves provides a universal guidance system that works with various tool types, while the adjustable positioning allows the same intermediate piece to adapt to different tool requirements without requiring completely different designs for each tool type.
Solution Approach 2:
The intermediate piece incorporates adjustable and movable elements, including the adjustable guide that allows height correction and the positioning mechanisms that enable lateral and longitudinal adjustment of the cutting tool. This dynamic capability allows a single intermediate piece design to adapt to multiple tool configurations, reducing the need for multiple specialized designs.
2Adaptability or versatility
If the intermediate piece is extended beyond the base carrier plate to provide greater distance between the cutting tool and receiving part, then the adaptability for elongated cutting tools is improved, but the length of the tool holder system increases
Solution Approach 1:
Instead of extending the intermediate piece only in the longitudinal direction, the design utilizes lateral extension along the tool carrier plate and base carrier plate. This dimensional approach allows the cutting tool to be positioned at an optimal distance from the receiving part while maintaining a compact overall structure. The guide structure extends laterally to provide the necessary support and guidance for elongated tools without excessively increasing the longitudinal length.
3Manufacturing precision
If the adjustable guide allows relative movement between base plate and tool carrier plate for height correction, then the manufacturing precision is improved to compensate for tool tolerances, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The adjustable guide acts as an intermediary mechanism between the base carrier plate and the tool carrier plate, providing height correction through a standardized interface. The guide teeth and guide grooves serve as the mediating elements that enable controlled relative movement while maintaining precise positioning. This intermediary structure allows height adjustment without requiring complex direct coupling mechanisms between the plates.
Solution Approach 2:
The adjustable guide incorporates dynamic elements such as adjusting screws and movable guide components that allow height correction while maintaining structural integrity. The mechanism enables controlled movement during adjustment and provides stable positioning when adjusted, achieving precision without excessive complexity through well-defined adjustment and locking stages.
4Volume of moving object
If the screw head of the adjusting screw is countersunk in the base support plate for compact design, then the volume of the tool holder system is reduced, but the ease of operation deteriorates due to reduced accessibility for adjustment
Solution Approach 1:
The base support plate is designed with localized features around the adjusting screw, including countersunk holes and potentially recessed areas or access channels that provide adequate workspace for adjustment operations. The countersinking is performed only in the specific location where the screw head sits, maintaining compactness in the overall structure while preserving operational accessibility at the adjustment point through local geometric modifications.
