Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the ultraviolet lamp body is fixed to the flexible tube, then the structure is stable, but the irradiation position cannot be adjusted to special angles

Engineering Contradiction:

Improveirradiation position adjustmentVSAvoidconnection structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nail lamp is divided into separable components: the ultraviolet lamp body and the flexible tube are designed as detachable parts through magnetic attraction connection. This segmentation allows the lamp body to be independently positioned at special angles while maintaining a simple overall structure when assembled.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The traditional mechanical fastening system (screws, clips, or adhesive) is replaced with a magnetic attraction system. The magnetic connection provides both secure attachment for structural stability and easy detachability for angle adjustment, eliminating complex mechanical fastening mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the nail lamp components are kept assembled, then the device is ready for use, but it occupies more space and increases damage risk during transportation

Engineering Contradiction:

Improvereadiness for useVSAvoidstorage space

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The nail lamp components (lamp body and flexible tube) are designed as separable units connected by magnetic attraction. During transportation, they can be detached and stored in a compact folded state, reducing volume. Before use, they are quickly reassembled through magnetic attraction, restoring full functionality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection state of the components transitions from static (permanently fixed) to dynamic (detachable on demand). The magnetic attraction connection enables the system to switch between assembled (ready for use) and disassembled (compact for storage) states, optimizing both accessibility and space efficiency.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the ultraviolet lamp body is detached for handheld use, then special angle irradiation is achieved, but the connection structure becomes more complex

Engineering Contradiction:

Improvehandheld use capabilityVSAvoiddetachable connection

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Complex mechanical detachable connection systems (such as bayonet mounts, screw threads, or snap-fits) are replaced with a simple magnetic attraction connection. This allows the lamp body to be easily detached for handheld use at special angles while keeping the connection mechanism simple and intuitive.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic attraction connection provides self-aligning and self-latching properties. When bringing the lamp body and flexible tube together, the magnetic force automatically guides them into the correct position and secures the connection, eliminating the need for complex alignment procedures or additional fastening steps.

Inventive Principle:

Principle #25Self-service
