Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the lighting device uses conventional assembly and disassembly processes, then the electrical connections can be established, but the process becomes complicated and does not comply with safety regulations

Engineering Contradiction:

Improvesafety regulation complianceVSAvoidassembly and disassembly process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The electrical connection process is segmented into distinct stages: the fixing module establishes the earth wire connection first, followed by the circuit module establishing the live and neutral wire connections. This segmentation ensures that safety-critical earth connection is made before power connections, complying with safety regulations while maintaining a systematic, manageable assembly process

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing module performs preliminary action by establishing the earth wire connection to the power source before the circuit module establishes the live and neutral wire connections. This preliminary grounding action ensures safety compliance is achieved in advance, creating a safe foundation before power connections are made

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the lighting device uses conventional assembly and disassembly processes, then the electrical connections can be established, but the process becomes complicated and time-consuming

Engineering Contradiction:

Improvesafety regulation complianceVSAvoidassembly and disassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The fixing module and circuit module are merged into an integrated assembly unit where both modules can be installed and connected simultaneously. The fixing module handles earth wire connection while the circuit module handles live and neutral wire connections, allowing parallel installation operations that reduce total assembly time while maintaining safety compliance through the predetermined connection sequence

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

AI summary

A lighting device and a lighting device assembling and disassembling method complying with safety regulations are provided. The lighting device includes a main body, a circuit module, a fixing module, and a backside plate. The backside plate includes a first electric connection slot corresponding to the fixing module and a second electric connection slot corresponding to a first electric connection part of the circuit module. In the assembling process, the fixing module is initially connected with the first electric connection slot, and the electric connection between these two components is established. While the fixing module is connected with the first electric connection slot, the electric connection between the first electric connection part and the second electric connection slot is established. Afterwards, the fixing module and the first electric connection slot are structurally connected with each other.
