Vise Support Bolt for One-Handed Clamping of Heavy Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vises require two-handed operation for heavy workpieces, necessitating additional assistance or unsafe one-legged handling, and existing retrofit solutions are not universally applicable.
Innovation Solution
A support bolt system that allows workpieces to be placed between vise jaws, enabling one-handed operation by providing a stable support surface for the workpiece, allowing the handle to be operated with one hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the workpiece is held with both hands to operate the handle, then the workpiece can be securely held, but the operator cannot operate the handle by hand
Solution Approach 1:
The support bolt acts as an intermediary element between the workpiece and the vise structure. It provides a stable support surface that allows the workpiece to be securely held while freeing the operator's hands to operate the handle. The support bolt transfers the weight and stability function from the operator's hands to the vise structure.
2Reliability
If a second person is involved to hold the workpiece, then the workpiece can be securely held and the handle operated, but time is lost and productivity is reduced
Solution Approach 1:
The vise system becomes self-servicing through the support bolt mechanism. The support bolt automatically provides the necessary support and stability for heavy workpieces without requiring external assistance. The operator can independently place the workpiece on the support bolt and operate the handle, making the system self-sufficient for handling heavy loads.
3Ease of operation
If the worker stands on one leg to turn the lever with thigh, then the lever can be turned without assistance, but the operation is cumbersome and dangerous
Solution Approach 1:
The support bolt serves as a mediator that eliminates the need for unsafe thigh-operated lever turning. By providing stable support for the workpiece, it allows the operator to safely and comfortably operate the handle with one hand, removing the dangerous posture requirement while maintaining independent operation capability.
4Ease of operation
If a retrofittable short-stroke module with hydraulic pump is installed, then the spindle can be rotated by foot pedal without hands, but the installation complexity increases and not all vise models are compatible
Solution Approach 1:
The complex hydraulic module is extracted and replaced with a simple support bolt mechanism. Instead of installing a sophisticated hydraulic system with pumps and hoses, the invention extracts only the essential function of providing support for the workpiece, achieving the same operational benefit with minimal added complexity and universal compatibility.
