Adjustable Vehicle Stand for Underfloor Battery Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle stand systems require large-scale construction and complex configurations to access batteries mounted under electric vehicles, especially when service bays are underground, necessitating significant space and vertical movement capabilities.
Innovation Solution
A vehicle stand system comprising separate stand parts with movable support portions that adjust to match the wheelbase and tread width of vehicles, allowing for efficient access and removal of batteries from under the floor without the need for extensive infrastructure, featuring H-shaped steel pillars and beams with movable wheel support portions to prevent falling and facilitate precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service bay is constructed underground to access batteries, then battery replacement is enabled, but the system requires large-scale construction and significant space
Solution Approach 1:
The vehicle stand is divided into multiple independent stand parts (first stand part with first and second support portions, second stand part with third and fourth support portions). Each stand part can be independently positioned and adjusted, eliminating the need for a large-scale underground service bay while still enabling battery replacement operations
Solution Approach 2:
The support portions are designed to be movable in vertical and horizontal directions, allowing the system to access batteries from above the vehicle rather than requiring underground access. This dimensional change from horizontal/underground access to vertical/overhead access reduces space requirements
2Adaptability or versatility
If support portions are made movable in multiple directions, then adaptability to different vehicle models is improved, but device complexity increases
Solution Approach 1:
The support portions are designed with movable capabilities in vertical and horizontal directions, allowing dynamic adjustment to accommodate different vehicle models and battery positions. This dynamic design enables a single stand system to adapt to various vehicle types without requiring multiple specialized systems
Solution Approach 2:
Each stand part and support portion is designed to perform multiple functions: supporting vehicle weight, positioning vehicles accurately, and enabling access to batteries from different angles. This multi-functionality reduces the need for additional specialized equipment

AI summary
A vehicle stand includes: first, second, third, and fourth support portions which support respective wheels of a vehicle; a first stand part which includes the first support portion and the second support portion; and a second stand part which includes the third support portion and the fourth support portion. Further, in the first stand part, the first support portion or the second support portion is movable in the width direction of the vehicle, and in the second stand part, the third support portion and the fourth support portion are movable in the longitudinal direction of the vehicle and the third support portion or the fourth support portion is further movable in the width direction of the vehicle.
