Solution Overview
Problem
Existing chassis components face challenges in simplifying and cost-effectively integrating measuring devices within joints, as massive interventions for structural modifications can weaken the structure and increase manufacturing costs.
Innovation Solution
A chassis component design featuring a measuring device with a first measurement element attached to the structural part and a second measurement element positioned outside the joint absorption, using a fastening system and alignment elements to ensure accurate orientation and prevent twisting, while maintaining structural integrity and reducing costs.

Engineering Contradiction Analysis
1Device complexity
If a blind hole-like recess is formed in the structural part for arranging a measuring element, then the measuring device can be integrated within the structural part, but the structural part requires massive interventions and machining that weaken its strength
Solution Approach 1:
The measuring device is segmented into two separate parts: the first measuring element remains integrated in the structural part, while the second measuring element is mounted on the inner joint part. This segmentation eliminates the need for blind hole machining in the structural part, preserving its strength while maintaining measurement functionality.
Solution Approach 2:
The inner joint part serves as an intermediary carrier for the second measuring element. Instead of directly modifying the structural part to house the measuring device, the inner joint part acts as a mediator that carries the measuring element externally, avoiding structural weakening.
2Measurement precision
If the measuring element is arranged as close as possible to the center of the kinematic point or joint center point, then measurement accuracy is improved, but manufacturing effort and costs increase
Solution Approach 1:
The system allows for dynamic positioning of the second measuring element on the inner joint part. While close-to-center positioning is optimal for precision, the design permits flexible mounting locations on the inner joint part's outer surface, enabling a compromise between measurement accuracy and manufacturing ease depending on specific application requirements.
Solution Approach 2:
The measurement function is extended to the outer surface of the inner joint part rather than being confined to the center region. This dimensional shift from central positioning to surface positioning allows manufacturers to choose optimal locations that balance precision requirements with manufacturing simplicity.
