Inverted Suspension Sensor Wire Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles with upright suspensions face challenges in protecting wheel speed sensors and sensor wires from debris and interference during operation, particularly when the suspension extends maximally.
Innovation Solution
The vehicle employs an inverted suspension system with strategically positioned wheel speed sensors and sensor wires, using a telescopic element and connecting elements to restrict sensor wire deformation and prevent interference with suspension components, ensuring protection from debris and maintaining operational freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an inverted suspension system is used, then the layout freedom of wheel speed sensors and sensor wires is improved, but the risk of sensor wire contact with suspension components during maximum extension increases
Solution Approach 1:
The sensor wire is pre-positioned and routed through guide structures before the suspension reaches its maximum extension point. The wire is arranged to pass through spaces that are only accessible when the suspension is in specific positions, ensuring that even when the suspension extends maximally, the wire cannot contact the suspension components.
Solution Approach 2:
Guide structures and spatial arrangements act as intermediaries between the sensor wire and suspension components. These intermediaries create controlled pathways that allow the wire to move with the suspension while preventing direct contact, thus protecting the wire from damage during maximum extension.
2Measurement precision
If the wheel speed sensor is positioned closer to the front wheel for better detection, then the measurement precision is improved, but the exposure to debris and harmful factors increases
Solution Approach 1:
The wheel speed sensor is nested within the inverted suspension structure, specifically positioned within the space formed by the outer tube and inner tube of the shock absorber. This nesting allows the sensor to be close to the wheel for accurate detection while being protected by the suspension components from debris and harmful factors.
Solution Approach 2:
The inverted suspension structure, which could potentially be a source of interference, is instead utilized as a protective barrier. The outer tube and inner tube of the shock absorber, which move during operation, create a protective environment around the sensor, converting the potential harm of close proximity into a beneficial protective effect.
