Adjustable Height Sensor Swing Arm for Chassis Versatility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing height sensors for motor vehicles have fixed swing arm lengths, necessitating the development of multiple molds and increasing costs due to the need for different swing arms to match various chassis suspension structures, leading to poor versatility.
Innovation Solution
A height sensor with an adjustable swing arm structure comprising a main arm and an auxiliary arm, allowing for adjustable working length through a cooperative connection relationship, including limiting slots and a fixing shaft, enabling flexible assembly to match different chassis suspension structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the swing arm length is fixed, then the structure is simple and easy to manufacture, but the sensor cannot be matched to different chassis suspension structures, resulting in poor versatility
Solution Approach 1:
The swing arm is divided into a main arm and an auxiliary arm that can be assembled together. The auxiliary arm can be selectively installed at different positions on the main arm to achieve different effective lengths. This segmentation allows a single basic structure to serve multiple functions by combining with different auxiliary components.
Solution Approach 2:
The main arm is designed as a universal base component that can work with auxiliary arms of different configurations. By changing only the auxiliary arm or its installation position, the same main arm can be adapted to different chassis suspension structures, achieving multi-functionality without redesigning the entire swing arm.
2Adaptability or versatility
If different swing arms are developed for different chassis suspension structures, then the sensor can match various vehicle models, but the number of molds increases and development costs rise
Solution Approach 1:
A universal main arm design serves as the core component that can be paired with different auxiliary arms or configured with auxiliary arms at different positions. This approach allows one main arm mold to produce components that can be assembled into multiple swing arm variants, significantly reducing the number of molds needed while maintaining the ability to match different vehicle models.
Solution Approach 2:
The auxiliary arm is designed to be attached to or integrated with the main arm, forming a composite swing arm structure. The auxiliary arm can be nested onto the main arm or connected through standardized interfaces, allowing flexible combination of components to achieve different effective lengths without requiring completely separate swing arm designs.

AI summary
A height sensor including a sensor body, a swing arm and a connecting rod. A first end of the swing arm is movably connected to the sensor body, and a second end of the swing arm is movably connected to the connecting rod. The swing arm is configured as a structure with an adjustable working length suitable for, and can be matched to, different chassis suspension structures, being highly versatile, with a low development cost and high development efficiency.
