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

VSEngineering 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

Engineering Contradiction:
Improveadaptability to different foundation conditionsVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

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

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improvemeasurement accuracyVSAvoidease of assembly
Core Design Contradiction:
Measurement precisionVSEase of manufacture

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

Inventive Principle:
Principle #15Dynamics

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

Inventive Principle:
Principle #35Parameter changes
