Clamping and Spreading Tool with Sliding Inner Rod
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools fail to provide both clamping and spreading forces efficiently, limiting their versatility in applications requiring both functions.
Innovation Solution
A tool with a handle assembly, a slidable bar, and an inner rod system that includes a detent mechanism, allowing the tool to switch between clamping and spreading configurations by adjusting the inner rod's position within the bar's slot, enabling variable span and force direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tool is designed to perform both clamping and spreading functions, then versatility is improved, but device complexity increases
Solution Approach 1:
The tool is designed with a single bar that can perform both clamping and spreading functions by repositioning an inner rod within a slot. The bar includes engagement surfaces at opposite ends, allowing it to function as both a clamping bar and a spreading bar depending on the inner rod's position, thereby achieving multi-functionality without requiring separate tools.
Solution Approach 2:
The inner rod is made movable within the slot of the bar, allowing dynamic reconfiguration of the tool between clamping and spreading modes. This dynamic adjustment mechanism enables the tool to adapt its function based on operational needs, resolving the contradiction between versatility and complexity by using a simple movable component rather than multiple fixed components.
2Adaptability or versatility
If the span of the tool is made adjustable to accommodate various workpieces, then adaptability is improved, but device complexity increases
Solution Approach 1:
The inner rod can be repositioned along the slot to adjust the span of the tool. This dynamic adjustment allows the user to modify the effective length and configuration of the bar to suit different workpiece sizes and applications, achieving adaptability through a simple sliding mechanism rather than complex adjustment systems.
Solution Approach 2:
The bar is segmented into functional zones with engagement surfaces at opposite ends and a slot running through it. The inner rod interacts with different portions of the slot to create varied span configurations, allowing the tool to be adapted to different applications through positional segmentation rather than physical segmentation into multiple components.

AI summary
A tool for providing a clamping force and a spreading force in the opposite direction of the clamping force. The tool includes a handle assembly having a trigger and a bar supported by the handle assembly. The bar is configured to move relative to the handle assembly when the trigger is actuated, and the bar includes a slot spanning from a first end of the bar to a second end of the bar. An inner rod is received within the slot, and a detent mechanism selectively couples the inner rod to the bar. The inner rod is received within the first end and coupled to the bar to provide the clamping force when the trigger is actuated, and the inner rod is received within the second end and coupled to the bar to provide the spreading force when the trigger is actuated.
