Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single LED control box is used without multiple independent output control interfaces, then the device complexity is reduced, but the adaptability to different lighting scenarios deteriorates

Engineering Contradiction:
Improveadaptability to different lighting scenariosVSAvoidcontrol box structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control box is segmented into multiple independent output control interfaces (first output control interface, second output control interface, etc.), each capable of independently controlling different LED lamps. This segmentation allows the system to adapt to different lighting scenarios while maintaining a unified control box structure, resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The control box is designed with multi-functionality by incorporating multiple independent output control interfaces that can work independently or in combination. Each interface can control different LED lamps according to different control signals, enabling the single control box to serve multiple lighting scenarios simultaneously, thus improving adaptability without proportionally increasing complexity.

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

2Reliability

If physical wire connections are used for LED control, then the connection reliability is improved, but the installation cost and installation time increase

Engineering Contradiction:
Improveconnection reliabilityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces the mechanical wire connection system with a wireless communication system. Wireless switches communicate with the control box through wireless signals (infrared, radio frequency, etc.), eliminating the need for physical connecting wires. This substitution maintains control reliability through wireless protocols while dramatically reducing installation time and complexity, as no wire routing or physical connections are required.

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

3Use of energy by moving object

If all LED lamps are controlled uniformly through a single interface, then the device complexity is reduced, but the energy consumption increases due to inability to control individual lamps

Engineering Contradiction:
Improveenergy consumptionVSAvoidcontrol interface
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The control interface is segmented into multiple independent output control interfaces, each capable of independently controlling specific LED lamps. This allows the system to activate only the necessary lamps based on actual lighting needs, reducing energy consumption compared to uniform control of all lamps. The segmentation of control interfaces justifies the increased complexity by enabling energy-efficient selective operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different output control interfaces can be assigned different control characteristics and functions tailored to specific lighting zones or lamps. This local quality approach allows optimized energy management where each interface can independently regulate its controlled LEDs based on local requirements, reducing overall energy consumption while the added complexity is justified by the localized optimization capabilities.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility
