Insulating Lift Table Wheel Clamp for High-Voltage Two-Wheeler Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Technicians working on high-voltage two-wheelers on conventional lifting tables face risks of electric shock due to the use of metal stands or vices, which can lead to short-circuits or inadvertent contact with electric components.
Innovation Solution
A lifting table with a table top and wheel vice made of electrically insulating materials, such as synthetic polymers, and a pneumatic actuator for movement, eliminating the risk of electric shock and allowing for adjustable and removable components for versatile use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal stands or metal wheel vice are used to hold the two-wheeler on the lifting table, then the structural strength and clamping force are improved, but the risk of electric shock to the technician increases
Solution Approach 1:
The patent extracts the conductive metal material from the wheel vice and replaces it with electrically insulating material, removing the harmful electrical conductivity while preserving the mechanical clamping function. This directly addresses the contradiction by eliminating the electric shock risk while maintaining structural strength.
Solution Approach 2:
The patent uses composite or alternative materials that provide both mechanical strength and electrical insulation properties. The wheel vice is made from materials that combine adequate structural strength with electrical insulating characteristics, resolving the contradiction between strength and safety.
2Object-affected harmful factors
If electrically insulating material is used for the wheel vice jaws, then the electric shock risk is reduced, but the clamping force and holding capability may be weakened
Solution Approach 1:
The patent employs materials that possess both electrical insulating properties and sufficient mechanical strength to provide adequate clamping force. This resolves the contradiction by finding material properties that satisfy both safety and functional requirements simultaneously.
Solution Approach 2:
The patent may adjust design parameters such as jaw surface area, contact pressure distribution, or jaw geometry to compensate for any reduction in clamping force, ensuring that the insulating material still provides adequate holding capability while maintaining electrical insulation.
3Ease of repair
If the wheel vice jaws are made as removable parts, then the ease of repair and replacement is improved, but the device complexity increases
Solution Approach 1:
The patent divides the wheel vice into separate modular components, specifically making the jaws removable from the main body. This segmentation allows individual jaws to be replaced independently when damaged, improving ease of repair while keeping the overall replacement process simple and manageable.
Solution Approach 2:
The removable jaw design allows the same jaw components to be used across different vice configurations or replaced with different jaw types as needed, providing versatility and ease of maintenance without significantly complicating the overall device structure.
