Innovation Solution

A vehicle add-on component with integrated capacitive motion sensors that detect user gestures contactlessly and a display device providing feedback, along with optional camera and touch-based sensors for enhanced functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate components (side mirror, indicator, camera, sensor) are mounted on the vehicle body, then each component can be optimized for its specific function, but the overall device complexity increases and requires multiple mounting locations

Engineering Contradiction:
Improvefunctional integrationVSAvoidnumber of separate components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate functional components (side mirror housing, indicator lens, camera module, and sensor elements) into a single integrated side mirror assembly. The mirror housing serves as a common structure that accommodates the indicator lens at its front end and the camera module at its rear end, eliminating the need for separate mounting brackets and locations for each component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The side mirror housing is designed as a multi-functional component that simultaneously serves as: (1) the structural housing for the side mirror, (2) the mounting structure for the indicator lens, (3) the mounting structure for the camera module, and (4) the protective enclosure for internal components. This universal design reduces the total number of parts required.

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

2Ease of operation

If multiple separate mounting locations are used on the vehicle body, then each component can be independently positioned, but the manufacturing precision and alignment requirements increase

Engineering Contradiction:
Improveinstallation simplicityVSAvoidalignment precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

By consolidating multiple mounting functions into a single side mirror housing structure, the patent eliminates the need for multiple separate mounting locations on the vehicle body. All components (mirror, indicator, camera) are positioned relative to a common reference frame provided by the housing, significantly reducing alignment precision requirements compared to mounting each component separately on the vehicle body.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If multiple separate components are used, then each component can be manufactured independently, but the overall production time and assembly complexity increase

Engineering Contradiction:
Improvemanufacturing flexibilityVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The integrated side mirror assembly allows multiple components to be manufactured as separate modules (mirror housing, indicator lens, camera module) that can be produced independently using optimized processes for each, then quickly assembled together in a single operation. This maintains manufacturing flexibility while reducing final assembly time compared to installing multiple separate components on the vehicle body.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The camera module and indicator lens are pre-assembled into the side mirror housing during manufacturing, creating a pre-integrated assembly that is then installed as a single unit on the vehicle. This preliminary integration during manufacturing eliminates the need for time-consuming on-vehicle alignment and installation of multiple separate components.

Inventive Principle:
Principle #10Preliminary action

4Ease of repair

If components are mounted separately on the vehicle body, then replacement of individual components is easier, but the overall device reliability decreases due to multiple mounting points

Engineering Contradiction:
Improvecomponent replaceabilityVSAvoidsystem reliability
Core Design Contradiction:
Ease of repairVSReliability

Solution Approach 1:

The side mirror assembly is designed with segmented modules (mirror housing, indicator lens, camera module) that can be independently accessed and replaced. The indicator lens can be replaced by accessing it through the front of the housing, while the camera module can be replaced by accessing it through the rear of the housing, maintaining ease of repair while reducing the number of external mounting points.

Inventive Principle:
Principle #1Segmentation
