Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional fluorescent lamp replacement is performed, then the lighting function is updated, but the replacement process is troublesome and requires high labor cost

Engineering Contradiction:
Improveease of replacementVSAvoidreplacement time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The LED lamp is divided into separate modular components: a lamp base with magnets, a lampshade, and an LED light source module. This segmentation allows the lamp base to be independently attached to the panel using magnetic force, while other components can be easily assembled or disassembled without affecting the magnetic attachment, thereby simplifying the replacement process and reducing labor time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional mechanical fastening systems (screws, clips, or adhesive mounting) with a magnetic field-based attachment system. The magnets mounted on the lamp base create magnetic attraction to the metal panel, enabling tool-free installation and removal, which significantly reduces replacement time and labor requirements.

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

2Reliability

If traditional mechanical fastening is used, then the lamp base is securely attached, but the assembly process is complex and time-consuming

Engineering Contradiction:
Improveattachment stabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent substitutes complex mechanical fastening mechanisms with a simple magnetic attachment system. The magnets on the lamp base provide reliable attachment to the metal panel through magnetic attraction, eliminating the need for screws, clips, or other mechanical fasteners. This reduces assembly complexity while maintaining secure attachment.

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

Solution Approach 2:

The patent changes the attachment mechanism from mechanical (contact-based fastening) to magnetic (field-based attraction). This parameter change in the attachment method simplifies the assembly process while ensuring reliable attachment through controllable magnetic force strength.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If the LED light source module is loosely positioned, then the assembly is simple, but the LED module becomes unstable and may loosen

Engineering Contradiction:
Improveassembly simplicityVSAvoidLED module stability
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The lampshade is designed with localized resisting sheets positioned at specific locations to provide targeted support and restraint to the LED light source module. These resisting sheets create local friction or mechanical resistance that prevents the LED module from loosening, while the rest of the assembly remains simple and easy to manufacture.

Inventive Principle:
Principle #3Local quality
