Solution Overview
Problem
Existing methods for supporting and guiding machine tools or workpieces are inadequate for precise machining, often causing damage to the workpiece and are difficult to handle due to the use of nails or screws for attachment.
Innovation Solution
A holding element with a detachable retaining element that uses a combination of adhesive and positive locking mechanisms, allowing for secure attachment to the workpiece without leaving residue and enabling precise positioning of machine tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If nails or screws are used to fasten the guide rail to the workpiece, then the guide rail achieves firm attachment, but the workpiece surface is damaged
Solution Approach 1:
The patent replaces the mechanical fastening system (nails or screws) with an adhesive bonding system. The adhesive agent is applied to the mounting surface of the support body, creating a chemical bond instead of a mechanical one, thereby avoiding penetration and damage to the workpiece surface while maintaining firm attachment.
Solution Approach 2:
The patent changes the bonding mechanism from mechanical interlocking (nails/screws) to chemical adhesion. By using an adhesive agent with appropriate bonding properties, the attachment method transitions to a non-invasive approach that preserves the workpiece surface integrity while achieving the required attachment strength.
2Manufacturing precision
If the guide rail is screwed to the substrate for precise workpiece machining, then positioning precision is improved, but handling becomes difficult due to fixed fastening points
Solution Approach 1:
The patent segments the fastening function from the support body by using a separate adhesive agent. This allows the support body to be positioned and adjusted freely during handling, and the adhesive is applied only when final positioning is achieved, combining ease of handling with positioning precision.
Solution Approach 2:
The patent enables preliminary positioning and adjustment of the support body before the adhesive sets. The adhesive agent provides initial bonding that allows for fine-tuning of the position, and once positioned correctly, the adhesive cures to provide permanent fixation, thus achieving both ease of handling during setup and precision in the final position.
3Object-affected harmful factors
If adhesive is used to attach the support body to the workpiece, then the workpiece surface is protected from damage, but the attachment firmness is insufficient for precise machining
Solution Approach 1:
The patent optimizes the adhesive agent parameters to achieve both surface protection and firm attachment. By selecting an adhesive with appropriate viscosity, bonding strength, and curing properties, the system achieves sufficient attachment firmness for precise machining while maintaining the benefit of non-invasive bonding that protects the workpiece surface.
