Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting and guiding machine tools or workpieces, such as guide rails, often require screws or nails for attachment, which can damage the workpiece and are not suitable for precise machining like saw cuts, and lack sufficient stability during machining processes.
Innovation Solution
A device with a contact body featuring a holding element that uses an adhesive means to securely attach to the work surface without leaving residue, allowing for precise positioning and firm fixation of machine tools, such as saws or routers, on sensitive or delicate workpieces, using a detachable and reusable adhesive system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screws or nails are used to attach the guide rail to the work surface, then the attachment stability is improved, but the workpiece surface is damaged
Solution Approach 1:
The patent replaces the mechanical fastening system (screws or nails) with an adhesive system. The holding element incorporates an adhesive means that chemically bonds to the work surface, providing stable attachment without mechanical penetration. This substitution eliminates the harmful mechanical intrusion while maintaining the necessary attachment stability for precise machining operations.
Solution Approach 2:
The patent changes the attachment parameter from mechanical force (screws/nails) to chemical bonding (adhesive). The adhesive means undergoes a parameter change from a non-adhesive state during positioning to an adhesive state that provides strong bonding, allowing stable attachment without damaging the workpiece surface.
2Object-affected harmful factors
If the guide rail is placed loosely with frictional components, then the workpiece surface is not damaged, but the attachment stability is insufficient for precise machining
Solution Approach 1:
The adhesive means undergoes a parameter change from a non-adhesive positioning state to an adhesive bonding state. During positioning, the adhesive is not yet activated, allowing easy adjustment. Once positioned, the adhesive activates to provide strong bonding, achieving both surface integrity and attachment stability.
Solution Approach 2:
The holding element incorporates a dynamic adhesive system that transitions from a mobile, easily adjustable state during positioning to a fixed, stable state during machining. This dynamic characteristic allows the system to provide both ease of positioning and firm attachment, resolving the contradiction between stability and surface integrity.
3Stability of the object's composition
If the adhesive means is always in contact with the work surface, then attachment stability is improved, but positioning precision is reduced
Solution Approach 1:
The adhesive means dynamically transitions between a non-contact positioning state and a contact adhesive state. During positioning, the adhesive is retracted or inactive, allowing precise adjustment without bonding. Once positioned, the adhesive engages to provide stable attachment, ensuring both positioning precision and attachment stability.
Solution Approach 2:
The holding element is segmented into a positioning function and an adhesive function. The adhesive means is separated from the contact surface during positioning and only engages when needed, allowing the positioning operation to be performed with high precision before the adhesive provides stabilization.

AI summary
A device for supporting and/or guiding a machine tool or a workpiece, wherein the device includes a contact body having a contact surface for contact on a work surface of a workpiece or a wall. It is provided that the contact body includes a holding element having an adhesive means for adhesion to the work surface, wherein the adhesive means, when the contact surface of the contact body bears against the work surface, can be brought from a positioning state, in which the adhesive means is not in contact with the work surface and the contact surface can be positioned with respect to the work surface into an adhesive state, in which the adhesive means adheres to the work surface and fixes the contact body on the work surface.
