Problem
Existing systems for measuring tyre characteristics require complex, costly, and time-consuming installation and repositioning due to high stress from vehicle traffic, which can lead to system malfunction and wear from vibrations and misalignment.
Innovation Solution
A ground attachment system featuring an attachment plate with recesses, frustoconical clamping rings, and cylindrical guide tunnels with complementary conical portions, allowing for secure and adjustable attachment without play, reducing wear and facilitating easy installation and repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If significant infrastructure is used to attach the unit to the ground, then the unit can withstand high stresses from vehicle traffic, but the installation becomes time-consuming and costly
Solution Approach 1:
The attachment system is divided into separate modular components: an attachment plate with multiple recesses, individual frustoconical clamping rings, and cylindrical guide tunnels. This segmentation allows for rapid assembly without requiring complex infrastructure or extensive ground preparation, significantly reducing installation time while maintaining attachment strength.
Solution Approach 2:
The frustoconical clamping rings act as intermediary elements between the attachment plate and the measurement unit. These rings fit into cylindrical guide tunnels and are secured with screws, providing a robust mechanical connection that distributes stress across multiple points. This intermediary mechanism eliminates the need for significant ground infrastructure while ensuring the unit can withstand high vehicle traffic loads.
2Strength
If significant infrastructure is used to attach the unit to the ground, then the unit can withstand high stresses from vehicle traffic, but the installation becomes costly
Solution Approach 1:
The attachment system uses simple, modular components that can be manufactured independently using standard machining processes. The attachment plate, clamping rings, and guide tunnels are separate pieces that can be produced in advance and assembled quickly on-site, eliminating the need for expensive ground preparation or specialized infrastructure installation.
Solution Approach 2:
The frustoconical clamping rings are relatively simple mechanical components that can be manufactured at low cost. If wear or damage occurs, these rings can be replaced individually without replacing the entire attachment system or requiring expensive reinstallation, making the overall system cost-effective over its service life.
3Strength
If the unit is attached using complex infrastructure, then it can withstand vehicle traffic stresses, but repositioning requires heavy equipment and major work
Solution Approach 1:
The modular segmented design allows the measurement unit to be detached from the attachment plate by simply removing the frustoconical clamping rings. The unit can be repositioned to different locations on the attachment plate by moving it to different guide tunnels, enabling quick repositioning without heavy equipment or complex procedures while maintaining secure attachment at each location.
4Ease of operation
If assembly clearances are present in the attachment system, then the system is easier to assemble, but wear increases and service life decreases
Solution Approach 1:
The frustoconical shape of the clamping rings and the matching conical portions in the guide tunnels create a self-aligning, interference-fit connection. The conical geometry provides natural guidance during assembly, allowing components to be easily inserted while eliminating play and minimizing wear through precise geometric engagement. This curved surface interaction ensures reliable, wear-resistant connections without requiring tight manufacturing tolerances.
