Workbench Groove with Locating Pin for Fixture Rod Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional workbenches with fixtures suffer from instability and safety hazards due to the rod's tendency to roll over and exposure to friction, leading to reduced service life and increased risk during use.
Innovation Solution
A workbench design featuring a first accommodating groove with a locating pin and elastic member to securely fix the rod, preventing movement and exposure, while allowing for easy detachment and improved user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rod is exposed to the outside for fixture operation, then the fixture can be easily operated, but the rod is susceptible to friction from objects to be processed, affecting service life and creating safety hazards
Solution Approach 1:
The rod is nested within a groove structure on the workbench surface. The groove accommodates the rod while protecting its exposed portion, allowing the fixture to operate freely above the work surface without the rod being directly exposed to friction from workpieces or tools.
Solution Approach 2:
The groove acts as an intermediary protective structure between the rod and the external environment. It provides a guided path for the rod while shielding it from direct contact with objects to be processed, thus reducing friction and safety hazards while maintaining operational capability.
2Adaptability or versatility
If the rod is allowed to move freely during fixture operation, then the fixture has flexibility, but the rod may roll over when subjected to large forces, causing instability
Solution Approach 1:
The rod is designed to be movable within the groove rather than fixed, allowing it to dynamically adjust its position as the fixture operates. This dynamic constraint within the groove provides both flexibility for fixture movement and stability by preventing uncontrolled rolling when forces are applied.
Solution Approach 2:
The groove provides localized constraints at specific positions along the rod's path, allowing freedom of movement in permitted directions while preventing rolling and instability. The local structural quality of the groove creates selective freedom and constraint zones.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the stability of the fixture, reduces safety hazards, and extends the service life by protecting the rod from external friction, allowing for convenient clamping of objects using the movable fixture body.
Implementation Method 1
a first elastic member configured for applying an elastic force on the locating pin, resulting in the locating pin extending into and remaining in the locating hole
