Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple independent functional devices with separate power supplies and housings are integrated into a luminaire, then the luminaire achieves high functionality with motion sensors, presence sensors, brightness sensors, control devices, and wireless communication, but the assembly process becomes very complex with extensive wiring and attachment requirements

Engineering Contradiction:
ImprovefunctionalityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple independent functional devices (motion sensor, presence sensor, brightness sensor, control device, wireless communication device) into a single integrated circuit board. This merging eliminates the need for separate housings and power supplies for each device, reducing assembly complexity while maintaining all required functionalities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated circuit board serves as a universal platform that hosts multiple functional devices simultaneously. This multi-functional design allows a single component (the circuit board) to perform the roles of several separate devices, simplifying the overall luminaire structure and assembly process.

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

2Adaptability or versatility

If multiple independent functional devices with separate power supplies and housings are integrated into a luminaire, then the luminaire achieves high functionality, but the installation becomes very complex due to extensive wiring and attachment of individual devices

Engineering Contradiction:
ImprovefunctionalityVSAvoidinstallation ease
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By merging all functional devices onto a single circuit board, the patent eliminates the need for complex wiring between separate devices. The integrated design requires minimal connection points to the luminaire's power supply and control systems, dramatically simplifying installation procedures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the complex system into two manageable parts: an integrated functional module (circuit board with all devices) and the luminaire housing. This segmentation allows the functional module to be pre-assembled and tested independently, then installed as a single unit, greatly easing the installation process.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple independent functional devices are integrated into a luminaire, then the luminaire achieves high functionality, but the space required for placement and wiring of individual devices increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent merges multiple space-consuming individual devices into a single compact circuit board. This consolidation reduces the total volume required for housing all functional components, allowing for more compact luminaire designs and better space utilization.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The circuit board acts as a nested structure that contains multiple functional devices within its circuitry. This nesting approach allows sensors, control circuits, and communication modules to be embedded within a single planar component, minimizing the space required for all functional elements.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If multiple independent functional devices with separate power supplies are used, then the luminaire achieves high functionality, but the risk of incorrect wiring, cable breaks, or circuit board tearing increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidwiring reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

By combining all functional devices onto a single rigid circuit board, the patent eliminates numerous inter-device connections that could fail. The integrated design removes cable connections between separate devices, preventing cable breaks and connection failures while ensuring reliable electrical connections through the board's inherent circuit traces.

Inventive Principle:
Principle #5Merging (Combining)
