Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for clamping tools that can effectively repair damage to pliable materials, such as automobile bodies, without causing further deformation or requiring repainting, especially for removing dents and deformities without the need for filler and sanding.
Innovation Solution
A C-shaped clamping tool with a drive screw assembly and adjustable backstops, allowing for precise application of compressive force using removable tool dies and guide pins, enabling the tool to be positioned in multiple configurations to accommodate various workpieces, and a handle for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional repair methods (filler and sanding) are used to repair dents and deformities, then the damage can be effectively repaired, but the vehicle body requires repainting which increases cost and time
Solution Approach 1:
The invention extracts and removes the damaged portion of the workpiece using a specialized cutting tool that can precisely remove dents and deformities without affecting the surrounding intact material, eliminating the need for filler and sanding operations
Solution Approach 2:
Instead of building up material to fill dents (traditional approach), the invention removes the damaged material and allows the underlying structure to be repaired or replaced, then restores the surface without requiring repainting
2Device complexity
If a fixed configuration clamping tool is used, then the structure is simple, but the tool cannot accommodate various workpieces and configurations
Solution Approach 1:
The clamping tool is divided into separate modular components including interchangeable clamping elements, adjustable positioning mechanisms, and detachable fixtures that can be reconfigured for different workpiece types and sizes
Solution Approach 2:
The tool incorporates adjustable and movable components such as sliding clamps, rotating positioning mechanisms, and flexible positioning arms that allow dynamic adaptation to various workpiece geometries while maintaining structural integrity
3Force
If high compressive force is applied to remove dents, then the deformity can be effectively removed, but the material may become further deformed or damaged
Solution Approach 1:
The tool applies compressive force through localized contact points using precisely positioned cutting edges and clamping surfaces that concentrate force only on the damaged areas, leaving the surrounding intact material unaffected
Solution Approach 2:
The tool design incorporates force distribution mechanisms and progressive cutting actions that gradually remove material while distributing stress, preventing sudden failures or further deformation of the workpiece
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 tool allows for efficient and precise application of force to repair dents and deformities in automobile bodies, maintaining the original shape of the material without repainting, providing a cost-effective alternative to traditional repair methods.
Implementation Method 1
Applying a steady and substantially high compressive force to the item may remove the dent of deformity
Implementation Method 2
A detent spring plunger may be coupled to the first body member adjacent to one of the two or more non-collinear backstop bushings

AI summary
A clamping tool of the type including a C-shaped body and a drive screw with a threaded portion in mechanical communication with a threaded receiver in one end of the C-shaped body and including at least two threaded receivers in one end of the C-shaped body, each adapted to separately and independently receive and support the threaded portion of the drive screw. A backstop may be included with a backstop pin extending from a surface of the backstop and at least two non-collinear backstop bushings in a second end of the C-shaped body. The at least two non-collinear backstop bushings may each be adapted to receive and support the backstop pin of the backstop, thereby providing more than one position of the backstop on the C-shaped body.
