Adhesive Guide Support for Precise Machining Without Surface Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for supporting and guiding machine tools or workpieces are inadequate for precise machining, as they often damage the workpiece and provide insufficient stability, especially during operations like saw cuts, due to the use of nails or screws for attachment.
Innovation Solution
A device with a detachable holding element that uses an adhesive, which can be removed without residue, to securely attach a contact body to the workpiece, allowing for precise positioning of machine tools like saws or routers without damaging the workpiece, and can adhere to various surfaces including sensitive materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If nails or screws are used to attach the guide rail to the workpiece, then the guide rail achieves firm fixation and stability, but the workpiece surface is damaged
Solution Approach 1:
The patent replaces the mechanical attachment system (nails or screws) with an adhesive bonding system. The holding element uses adhesive material to attach the guide rail to the workpiece, eliminating the need for penetrating fasteners that damage the workpiece surface while providing sufficient fixation stability for precise machining operations
Solution Approach 2:
The patent changes the attachment parameter from mechanical penetration (nails/screws) to chemical bonding (adhesive). The adhesive material properties are selected to provide adequate bond strength for guide rail fixation while being removable without damaging the workpiece surface, thus resolving the contradiction between firm attachment and surface integrity
2Object-affected harmful factors
If the guide rail is placed loosely with friction-locking components, then the workpiece surface is not damaged, but the guide rail lacks sufficient stability for precise machining
Solution Approach 1:
The patent replaces the friction-based mechanical retention system with an adhesive bonding system. The adhesive provides positive attachment that ensures guide rail stability for precise machining operations while still preserving the workpiece surface, overcoming the insufficiency of loose friction-locking placement
3Stability of the object's composition
If holes are drilled in the guide rail for screw attachment, then the guide rail can be firmly fixed, but the handling becomes difficult and the workpiece is damaged
Solution Approach 1:
The patent eliminates the need for holes and screw attachment by using adhesive bonding. The holding element is attached to the guide rail using adhesive, which does not require drilling holes, thereby maintaining guide rail handling ease while achieving firm fixation through the adhesive bond
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure and residue-free attachment method, enabling precise machining by ensuring the machine tool is firmly positioned relative to the workpiece, reducing damage and improving handling precision.
Implementation Method 1
an adhesive is provided which can be removed again from the work surface, in particular without leaving any residue, without damaging the work surface

AI summary
The invention relates to a device for supporting and/or guiding a machine tool (20) or a workpiece (W). The device has a contact body (40) with a contact surface (42) for placing on a support surface (H) of a workpiece (W) or a wall. The contact body (40) has a holding element (60, 860, 960) with an adhesive (70) for adhering to the working surface (H), wherein when the contact surface (42) of the contact body (40) is resting against the working surface (H), the adhesive (70) can be brought from a positioning state (PZ), in which the adhesive (70) is not in contact with the working surface (H) and the contact surface (42) can be positioned relative to the working surface (H), into an adhesive state (HZ), in which the adhesive (70) adheres to the working surface (H) and the contact body (40) is fixed to the working surface (H).
