Solution Overview

Problem

Existing vehicle sensor devices, such as those with camera systems, require significant space and generate noise due to their design, which complicates integration and protection.

Innovation Solution

A compact sensor device with a movable sensor unit and protective element, utilizing a lever mechanism with rotary bearing points and a coaxial arrangement of the protective, decorative, and lever components, allowing for quiet operation and space-efficient design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If guide rails or slideways are used for sensor unit movement, then the sensor unit can be moved between rest and operating positions, but the device requires a lot of installation space and generates noise

Engineering Contradiction:
Improvesensor unit movementVSAvoidinstallation space
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The patent replaces the mechanical guide rail or slideway system with a lever mechanism comprising only rotary bearings. This substitution eliminates the need for linear guides while maintaining the sensor unit's ability to move between rest and operating positions, thereby reducing installation space requirements and noise generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention changes the movement mechanism from linear translation along guides to rotational movement around pivot points. By transforming the motion parameter from linear to angular, the device achieves compactness and reduced space requirements while maintaining full operational capability.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If guide rails or slideways are used for sensor unit movement, then the sensor unit can be moved between rest and operating positions, but the device generates noise

Engineering Contradiction:
Improvesensor unit movementVSAvoidnoise
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent replaces the mechanical guide rail or slideway system with a lever mechanism comprising only rotary bearings. This substitution eliminates the need for linear guides while maintaining the sensor unit's ability to move between rest and operating positions, thereby reducing installation space requirements and noise generation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Volume of stationary object

If the protective element and decorative element are arranged adjacent to one another, then the device has a compact design, but the sensor unit requires sufficient protection in rest position

Engineering Contradiction:
Improvedevice compactnessVSAvoidsensor unit protection
Core Design Contradiction:
Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent merges the protective element and decorative element into a single integrated assembly that moves together with the lever mechanism. This combination allows both functions (protection and aesthetics) to be achieved in a compact arrangement, with the elements moving synchronously between closed and open positions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The protective element serves dual functions: it protects the sensor unit when closed and acts as a decorative element when open. This multi-functionality allows the same component to satisfy both protection requirements and aesthetic considerations without requiring separate dedicated structures.

Inventive Principle:
Principle #6Universality (Multi-functionality)
