Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a conventional light bulb is used as the light source, then the working light can provide illumination, but the light is dispersed and cannot be gathered, resulting in insufficient eyesight

Engineering Contradiction:

ImproveeyesightVSAvoidlight gathering structure

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent divides the light source into multiple LED modules instead of using a single conventional bulb. Each LED module can be independently positioned and oriented to direct light precisely, eliminating the need for complex light gathering structures while improving eyesight through targeted illumination.

Inventive Principle:

Principle #1Segmentation

2Reliability

If a conventional light bulb is used, then the working light can function, but it consumes high power and is non-recyclable, being environmentally unfriendly

Engineering Contradiction:

Improveenvironmental friendlinessVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent changes the fundamental parameters of the light source by replacing conventional bulbs with LED modules. LEDs operate at lower power consumption levels and have longer lifespans, making the working light more environmentally friendly and energy-efficient while maintaining reliable functionality.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the working light is designed as a single module, then the structure is simple, but it cannot be repaired conveniently and has limited application

Engineering Contradiction:

Improveapplication flexibilityVSAvoidmaintenance convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of repair

Solution Approach 1:

The patent segments the working light into multiple independent LED modules that can be individually replaced or adjusted. This modular design enables convenient maintenance by allowing damaged modules to be swapped out without affecting the entire system, while also providing application flexibility through reconfigurable module arrangements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent incorporates adjustable mechanisms that allow the LED modules to be dynamically repositioned and reconfigured. This dynamic capability enables the working light to adapt to different application scenarios and facilitates easy maintenance through module replacement without requiring complex disassembly procedures.

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If the base of the working light is tilted, then the design is compact, but the working lights cannot be stacked with each other, limiting application

Engineering Contradiction:

Improvestacking capabilityVSAvoidbase configuration

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The patent designs the base with a universal configuration that serves multiple functions: it maintains a compact form factor while also enabling stacking capability. The standardized base design allows multiple working lights to be stacked vertically, expanding application possibilities without compromising the compact structure.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A working light includes a frame and a plurality of LED modules located in the frame. Two supporting plates at two ends of the frame are respectively combined with two ratchets. Two ends of the LED modules are combined with ratchet plates. The ratchets are respectively assembled to the ratchet plates to control a rotation angle of the LED modules. The working lights can be stacked with each other in one or more directions. The ratchets are at the side portions of the LED module. Therefore, after the LED module is assembled in the frame of the working light, the ratchets allow the LED module to be rotatable within 180 degrees. Hence, the LED module can be rotated, so that the illumination angle of the LED module is adjustable.
