Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If separate lighting devices are used in sensor devices, then lighting function is provided, but installation time and effort increase

Engineering Contradiction:
Improveinstallation time and effortVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines the sensor device and lighting device into a single integrated module. The housing contains both the sensor unit and lighting unit, which are electrically connected through a common connector. This merging eliminates the need for separate installation of lighting devices, directly reducing installation time and effort while maintaining both sensing and lighting functions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated module serves multiple functions simultaneously: it provides sensor detection capabilities (inductive, capacitive, or optical sensors) and lighting functions (LED or other light sources) within a single device. This multi-functionality allows the same component to replace both separate sensor and lighting devices, simplifying the overall system structure.

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

2Ease of manufacture

If separate lighting devices are used in sensor devices, then lighting function is provided, but installation space increases

Engineering Contradiction:
Improveinstallation spaceVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

By merging the sensor device and lighting device into a single integrated housing, the patent significantly reduces the total installation space required. The compact design places both functional units within one module, eliminating the need for separate mounting locations and reducing the overall footprint in the vehicle door assembly.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If separate lighting devices are used in sensor devices, then lighting function is provided, but manufacturing processes become more complex

Engineering Contradiction:
Improvemanufacturing processVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The integrated module can be manufactured as a single unit or pre-assembled package, simplifying the manufacturing process. Both the sensor and lighting components are housed together with shared electrical connections, reducing the number of separate manufacturing and assembly steps required compared to installing separate devices.

Inventive Principle:
Principle #5Merging (Combining)

4Productivity

If integrated sensor and lighting device is used, then installation time and space are reduced, but device integration complexity increases

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidintegration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

While integrated, the module maintains internal segmentation between the sensor unit and lighting unit, each with their own housings and electrical connections. This segmentation allows for modular manufacturing and assembly, where the sensor and lighting components can be produced separately and then integrated into the final module, reducing the complexity of integration while maintaining installation efficiency.

Inventive Principle:
Principle #1Segmentation
