Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a PC board (common light guide plate) is used to transmit light, then the light intensity is weakened, but the light becomes non-uniform, harsh, and easy to age, yellow and crack

Engineering Contradiction:
Improvelight intensityVSAvoidlight uniformity and durability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The patent divides the light guide plate into multiple layers: a diffusion layer and a reflection layer. This segmentation allows the light to be diffused uniformly while reflecting unwanted directions, solving the non-uniform light distribution and durability issues of single-layer PC boards

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses a composite structure combining diffusion material and reflection material in different layers of the light guide plate. This composite approach achieves both uniform light diffusion and improved durability by distributing stress and light interaction across different material properties

Inventive Principle:
Principle #40Composite materials

2Device complexity

If a rotating shaft is integrated through injection molding, then the structure is compact, but it cannot be disassembled, assembled and changed, has short service life, is easy to damage and must be completely replaced after being damaged

Engineering Contradiction:
Improverotating shaft structureVSAvoidservice life and replaceability
Core Design Contradiction:
Device complexityVSEase of repair

Solution Approach 1:

The rotating shaft is divided into multiple detachable segments connected by connecting pieces. This segmentation allows individual segments to be replaced if damaged, eliminating the need to replace the entire integrated shaft while maintaining structural compactness

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable design allows damaged segments to be discarded and replaced with new or recovered segments. The connecting pieces enable easy assembly and disassembly, extending the overall service life of the rotating shaft system

Inventive Principle:
Principle #34Discarding and recovering

3Device complexity

If a clamping base and desk lamp main body are connected in one direction only, then the connection is simple, but the clamping direction and position are limited

Engineering Contradiction:
Improveconnection structureVSAvoidclamping direction and position
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a rotating connection mechanism between the clamping base and lamp main body, allowing dynamic adjustment of the lamp's angle and direction. This enables the lamp to adapt to different clamping positions and orientations while maintaining a relatively simple connection structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotating connection mechanism provides multi-directional clamping capability, making the same connection structure adaptable to various clamping positions and angles, thereby achieving universal applicability without significantly increasing structural complexity

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

AI summary

A foldable clamp-on desk lamp with a multi-angle adjustment function includes: a lamp base part, a clamping base, several supporting rods, and detachable rotating shaft assemblies through which the several supporting rods are movably connected and the lamp base part is connected to the uppermost supporting rod. The lowermost supporting rod is detachably connected to the clamping base. The detachable rotating shaft assemblies can achieve folding and telescopic functions, complete disassembly, repeated disassembly, assembly and change, and long service life. By the design combining a Fresnel lens and convolutional lines, light is continuously scattered and recombined when passing through the convolutional lines, so that the outgoing light is more uniformly, soft, and not dazzling. A plurality of inserting holes are formed at the upper side and top end of the clamping base, thereby facilitating multi-directional assembling of the supporting rods and achieving wide application of the clamping position.
