Adhesive Holding Element for Damage-Free Tool Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for supporting and guiding machine tools or workpieces, such as guide rails, often damage the workpiece with screws or nails and are difficult to handle, especially for precise machining tasks.
Innovation Solution
A holding element with a combination of adhesive and form-locking contours for secure attachment to a workpiece, allowing for easy replacement of worn retaining elements and enabling precise positioning of machine tools without damaging the surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or nails are used to fasten the guide rail to the workpiece, then the attachment strength is improved, but the workpiece surface is damaged
Solution Approach 1:
The patent replaces the mechanical fastening system (screws or nails) with an adhesive bonding system. The adhesive layer is applied between the guide rail and the workpiece surface, creating a chemical bond instead of a mechanical one, thereby achieving strong attachment without penetrating or damaging the workpiece surface.
2Object-affected harmful factors
If the guide rail is loosely placed on the workpiece with friction-fit components, then the workpiece surface is protected, but the holding stability is insufficient for precise machining
Solution Approach 1:
The patent merges two retention mechanisms into a single system: friction-fit components (such as rubber elements) and adhesive bonding. The friction-fit components provide initial positioning and protection, while the adhesive layer provides additional bonding strength, together achieving both surface protection and sufficient holding stability for precise machining.
3Stability of the object's composition
If retaining elements are permanently fixed to the support body, then the structural integrity is improved, but the replaceability of worn components is lost
Solution Approach 1:
The patent segments the retaining element system into detachable components. The retaining elements (such as rubber friction-fit components) are made as separate, replaceable parts that can be independently removed and replaced. The support body includes receptacles or mounting structures that allow for easy installation and removal of these retaining elements, maintaining structural integrity while enabling component replaceability.
