Braking Sensor Mounting Asymmetry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle engine compartments, the cramped space often leads to incorrect mounting of vacuum measurement sensors, causing pipe damage and loss of effectiveness in the braking system due to contact with other elements, which is accident-prone.
Innovation Solution
A braking assistance device with a cylindrical portion and a vacuum measurement sensor featuring a cylindrical endpiece and fixing means, including anti-rotation fingers and a clamp mechanism, ensures correct orientation and secure positioning of the sensor to prevent pivoting and contact with other elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vacuum sensor is installed in the engine compartment without proper orientation constraints, then the sensor can be mounted, but the hose may come into contact with other components causing damage or rupture
Solution Approach 1:
The sensor mounting element incorporates asymmetric features including a single planar support face and corresponding planar receiving face, along with asymmetric locking tabs positioned at specific locations. This asymmetric design ensures the sensor can only be mounted in the correct orientation, preventing hose contact with other components while maintaining reliable braking system operation
Solution Approach 2:
A separate sensor mounting element is introduced as an intermediary component between the sensor and the brake booster. This mounting element provides the planar support and locking features that constrain sensor orientation, thereby protecting the hose from contact damage without modifying the sensor or brake booster directly
2Ease of operation
If the sensor mounting allows pivoting about the main axis of the bore, then the sensor can be installed with some orientation flexibility, but the hose may repeatedly contact components causing damage
Solution Approach 1:
The sensor mounting element incorporates locking tabs that engage with corresponding features on the sensor before any pivoting or movement can occur. This preliminary constraint prevents the sensor from pivoting about the bore axis, thereby preventing repeated hose contact with components while still allowing straightforward installation
3Adaptability or versatility
If a hose is connected to the vacuum sensor without orientation constraints, then the sensor can be mounted in various orientations, but the hose may come into contact with other elements causing system failure
Solution Approach 1:
The asymmetric mounting element with its single planar support face and positioned locking tabs provides constrained adaptability - the sensor can be installed in only one correct orientation rather than multiple orientations. This ensures the hose is positioned away from other components, maintaining braking system effectiveness while still providing straightforward installation
