Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measuring sensors are directly attached to the rim section, then measurement precision is improved, but device complexity and difficulty of installation increase
Solution Approach 1:
A metal strip is introduced as an intermediary element between the rim section and the measuring sensor. The metal strip is attached to the outer circumference of the rim section and serves as a mediator that transfers the mechanical deformations of the rim to the measuring sensor, enabling accurate load force detection without direct attachment of the sensor to the rim itself.
Solution Approach 2:
The measuring device is segmented into separate functional components: the metal strip attached to the rim, the bending strut with measuring sensor, and the housing. This segmentation allows each component to be optimized independently and simplifies installation, as the components can be assembled in a standardized sequence regardless of specific wheel geometry variations.
2Measurement precision
If measuring device is directly mounted on rim section, then measurement precision is improved, but adaptability to different wheel geometries deteriorates
Solution Approach 1:
The metal strip serves multiple functions: it attaches to the rim section, transfers mechanical deformations, and provides a standardized mounting surface for the measuring sensor. This universal interface allows the same measuring device design to be adapted to different wheel geometries while maintaining measurement precision through the consistent deformation transfer mechanism.
3Ease of manufacture
If housing is fastened to rim well base by adhesion, then ease of manufacture is improved, but reliability under high centrifugal forces deteriorates
Solution Approach 1:
The metal strip is pre-attached to the rim section with sufficient adhesive strength to withstand the centrifugal forces generated during vehicle operation. This preliminary action ensures that the metal strip remains securely fixed to the rim, providing a stable base for the measuring sensor to accurately detect rim deformations even under high-speed conditions.
