Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional wireless networking technologies (Wi-Fi, Bluetooth mesh, Zigbee) are used for multi-node lighting control, then wireless connectivity and remote control capability are achieved, but equipment identification becomes difficult and networking complexity increases

Engineering Contradiction:
Improveequipment identificationVSAvoidnetworking complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a laser beam as an intermediary carrier to transmit control instructions from the remote controller to the target lamp. This laser intermediary enables direct, intuitive pointing control, eliminating the complexity of traditional wireless device discovery and pairing processes while improving equipment identification ease.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical/electronic wireless networking protocols (Wi-Fi, Bluetooth, Zigbee) with an optical laser-based control system. This substitution simplifies the control mechanism by using direct laser pointing instead of complex wireless protocol handshaking and device selection procedures.

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

2Reliability

If traditional wireless networking technologies are deployed in dense multi-node environments, then wireless control coverage is achieved, but signal interference causes command delays or losses

Engineering Contradiction:
Improvecontrol command transmissionVSAvoidsignal interference
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes radio frequency wireless communication (prone to interference) with optical laser communication. The laser beam provides a dedicated, interference-free transmission path between the remote controller and target lamp, ensuring reliable control command delivery in dense environments without signal collision or interference.

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

Solution Approach 2:

The laser-based control system creates a localized, directed transmission path from the remote controller to the specific target lamp. This localized quality ensures that control commands are transmitted only to the intended recipient without interfering with or being interfered by other devices in the environment, improving reliability.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If laser assistance is introduced for precise lamp positioning and control, then equipment identification accuracy and control precision are improved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into the remote controller and receiver units: the remote controller combines laser emission, wireless network connectivity, and control signal generation; the receiver integrates laser reception, instruction decoding, and wireless communication. This multi-functionality achieves precise positioning and control without proportionally increasing overall system complexity.

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

Solution Approach 2:

The patent merges the laser positioning system with the wireless control system into an integrated architecture. The laser unit and wireless communication unit work together in a unified control flow, where the laser provides targeting and the wireless system provides command transmission, creating a cohesive system rather than separate complex subsystems.

Inventive Principle:
Principle #5Merging (Combining)
