Cutting Device Fence Interposing Member Warped Base Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal machining cutting devices face operability and usability issues due to unevenness in the base surface, which affects the positioning and direction changes of the fence, leading to worsened performance.
Innovation Solution
A cutting device with a fence that uses an interposing member fixed to the base via a first and second fixing member, allowing the fence to be indirectly fixed to the base, enabling rotation around a rear axis for position changes, and incorporating a biasing member for improved positioning and repeatability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tool-less construction is applied to the base made of metal sheet parts, then the ease of operation is improved, but the manufacturing precision deteriorates due to welding strains causing base wave-forming
Solution Approach 1:
The patent introduces an interposing member as a mediator between the fence and the base. This interposing member has a first surface that contacts the base and a second surface that contacts the fence. By placing this intermediary component between the fence and the warped base, the system maintains the tool-less operational ease while compensating for the base's manufacturing imprecision through the interposing member's flat contact surfaces
Solution Approach 2:
The patent divides the fixing system into multiple independent components: the base, the interposing member, and the fence, connected through separate fixing members. This segmentation allows the interposing member to independently compensate for base warping while maintaining its relationship with the fence, thus preserving ease of operation despite base manufacturing variations
2Device complexity
If the fence is directly fixed to the base, then the device complexity is reduced, but the operability deteriorates due to unevenness in fastening position
Solution Approach 1:
The interposing member serves as a mediator that provides a stable, flat interface between the fence and the potentially warped base. This intermediary component ensures consistent fastening positions for the operational lever without significantly increasing overall device complexity, as the interposing member integrates smoothly into the existing fence structure
3Ease of operation
If the fence is indirectly fixed via an interposing member, then the operability is improved by reducing variation in operating amount, but the device complexity increases
Solution Approach 1:
The interposing member acts as a mediator that provides a stable reference plane for the fence, ensuring consistent operating amounts for the operational lever. The design minimizes complexity by making the interposing member a simple plate-like component that can be easily integrated into the existing fence assembly without requiring complex mechanisms

AI summary
An interposing member is interposed between a base part of the fence plate and a top plate part of a base, and a position of the fence plate is changed on the interposing member. Because of this, deflection etc. of the top plate can be reduced and variation of an operating angle of an operating lever can be reduced when fixing the fence plate to the base.
