Overlapping Wheel Sensor Assembly for Knuckle Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wheel sensor devices for vehicles degrade the stiffness of the knuckle when multiple sensors are mounted, as they require multiple holes for installation, compromising the structural integrity and necessitating a solution that enhances both stiffness and sensor functionality.
Innovation Solution
A wheel sensor device design featuring multiple sensor parts with overlapping configurations and shared fixing holes, allowing for the integration of multiple sensors without the need for individual mounting on the knuckle, thereby maintaining stiffness and enhancing sensor functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensor devices are mounted on the knuckle, then the sensor function is enhanced, but the stiffness of the knuckle is degraded
Solution Approach 1:
Multiple sensor parts (first sensor part, second sensor part, third sensor part) are merged into a single integrated assembly that mounts to the knuckle through one common fixing hole, rather than requiring separate mounting holes for each sensor. This merging approach maintains the enhanced sensor function while preserving the stiffness of the knuckle.
Solution Approach 2:
The integrated sensor assembly serves multiple sensing functions simultaneously through its multiple sensor parts, while the single mounting structure provides universal attachment to the knuckle. This multi-functionality allows the system to achieve enhanced sensor capabilities without compromising structural integrity.
2Adaptability or versatility
If multiple holes are formed in the knuckle for mounting sensors, then multiple sensors can be installed, but the structural integrity is compromised
Solution Approach 1:
Multiple sensor parts are combined into a single mounting unit that requires only one fixing hole in the knuckle. The first, second, and third sensor parts are all secured through this single common fixing hole, eliminating the need for multiple separate holes and thus preserving structural integrity while maintaining installation versatility.
Solution Approach 2:
The multiple sensor parts are arranged in an overlapping configuration where they nest within the same mounting space, allowing them to be secured through a single fixing hole. This nesting arrangement enables multiple sensors to be installed without requiring multiple holes in the knuckle.
3Reliability
If multiple sensor devices are mounted separately, then each sensor can function independently, but the device complexity increases
Solution Approach 1:
The mounting structures of multiple sensor devices are merged into a single integrated fixing mechanism. The first, second, and third sensor parts share a common mounting interface that is secured through one fixing hole, reducing the overall device complexity while maintaining independent sensor functionality through their overlapping arrangement.

AI summary
A wheel sensor device for a vehicle may include: a first sensor part having a first fixing hole, inserted into an insertion space of a knuckle of a vehicle, and configured to sense wheel speed of the vehicle; a second sensor part overlapping the first sensor part, inserted into the insertion part with the first sensor part, having a second fixing hole aligned with the first fixing hole, and configured to sense the wheel speed; and a fixing member fixed to a mounting structure of the knuckle through the first and second fixing holes.
