Solution Overview
Problem
Existing sensor support devices in vehicles and technical buildings are complex and time-consuming to produce due to their multi-functional nature, which includes securing sensors, isolating them from vibrations, and providing electrical grounding.
Innovation Solution
A one-piece sensor support with an integrally formed damping member and frame, featuring an elastic and rigid portion to isolate sensors from vibrations and an electrically conductive plastic material for grounding, along with a hinged closure door for easy sensor insertion and secure mounting to a structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-functional sensor support device is used (including mounting base, frame, damping pad, and electrical connection), then the sensor can be securely mounted with vibration isolation and grounding, but the device complexity and production time increase
Solution Approach 1:
The patent combines multiple separate components (mounting base, frame, damping pad, and electrical connection elements) into a single integrated support device. The support includes a body with a receiving space defined by first and second walls, where the damping pad is integrated as part of the support structure itself. This merging of functions into one component reduces assembly steps and overall device complexity while maintaining all necessary functions for secure sensor mounting, vibration isolation, and electrical grounding.
2Reliability
If a multi-functional sensor support device is used (including mounting base, frame, damping pad, and electrical connection), then the sensor can be securely mounted with vibration isolation and grounding, but the production time increases
Solution Approach 1:
The patent combines multiple separate components (mounting base, frame, damping pad, and electrical connection elements) into a single integrated support device. The damping pad is integrated as part of the support structure itself, and the electrical connection is formed through conductive elements that are part of the support body. This merging of functions into one component reduces assembly steps and overall production time while maintaining all necessary functions for secure sensor mounting, vibration isolation, and electrical grounding.
3Object-affected harmful factors
If a damping pad made from rubber-based material bonded to the frame is used, then vibration isolation is achieved, but the manufacturing process becomes more complex
Solution Approach 1:
The patent employs a damping pad made from viscoelastic material that is integrated with the support structure. The support body itself is made from a composite material comprising a matrix material and discrete conductive particles, creating an electrically conductive structure. This composite approach allows the damping pad to provide vibration isolation while being manufactured as part of the support structure, eliminating the need for separate bonding processes and simplifying manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution simplifies production while effectively isolating sensors from vibrations and providing reliable electrical grounding, ensuring accurate measurements by reducing complexity and production time.
Implementation Method 1
the shock-absorbing member comprises an elastic portion and a rigid portion, the elastic portion being arranged between the frame and the rigid portion so that, in use when the sensor is in place, the elastic portion deforms allowing the rigid portion to come into contact with said sensor, the elastic portion exerting a force on said rigid portion ensuring contact of the rigid portion with the sensor
Implementation Method 2
the support is made molded from electrically conductive plastic material, loaded with metallic particles, so that the electrical connection to the electrical ground is ensured by the support itself
