Adjustable Foot Test Stand for Foundation Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor vehicle test stands require precise adjustment of the foundation depth and complete levelness to avoid measurement inaccuracies, which is labor-intensive due to the need for extensive adjustments and the use of heavy roller sets.
Innovation Solution
The motor vehicle test stand features adjustable feet that allow vertical position adjustment without lifting the roller unit, enabling compensation for unevenness and differing foundation dimensions, and incorporates load cells for accurate weight determination, with components designed for easy assembly and pre-assembly before installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adapter plates are placed underneath to compensate for height differences and unevenness in the foundation, then the test stand can be adapted to different foundation conditions, but the roller set must be raised several times during height adjustment which represents a considerable effort due to its high weight
Solution Approach 1:
The adjustable feet are pre-assembled to the test stand frame before installation, with the mounting plates already attached to the feet. This preliminary preparation allows the feet to be directly installed onto the foundation without requiring multiple lifting operations of the heavy roller set, thereby reducing assembly time while maintaining adaptability to different foundation conditions
2Measurement precision
If the foundation depth is adjusted very precisely and the foundation is made completely level, then measurement accuracy is ensured, but extensive adjustments to the foundation are required which is labor-intensive
Solution Approach 1:
The adjustable feet incorporate threads and locking mechanisms that allow for dynamic height adjustment after the test stand is installed on the foundation. This enables the mounting plates to be positioned at different heights to compensate for foundation unevenness, ensuring measurement accuracy without requiring extensive preliminary adjustments to the foundation itself
Solution Approach 2:
The adjustable feet allow changing the vertical position parameter of the test stand frame relative to the foundation. By rotating the threads of the adjustable feet, the height can be precisely adjusted to achieve the required levelness and measurement accuracy without modifying the foundation depth
