Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional bulbs or fluorescent lamps are used in natural light tubes, then lighting deficiency can be compensated, but energy efficiency deteriorates and space occupation increases
Solution Approach 1:
The patent replaces conventional bulbs with LED modules that have significantly longer service life, eliminating the need for frequent replacements and reducing long-term energy consumption. The LED modules are designed to operate continuously without burning out, providing sustainable lighting solution.
Solution Approach 2:
The patent changes the light source from thermal radiation (conventional bulbs) to electroluminescence (LEDs), fundamentally altering the energy conversion mechanism. This parameter change results in superior energy efficiency while maintaining adequate illumination intensity.
2Illumination intensity
If conventional bulbs are installed in natural light tubes, then lighting can be provided, but the bulb occupation space prevents sunlight passage
Solution Approach 1:
The patent divides the lighting function into separate modules: natural light collection through transparent tubes and artificial light supplementation via LED modules. The LED modules are designed as flat, space-efficient components that can be integrated into the tube structure without significantly obstructing sunlight passage.
Solution Approach 2:
The patent transitions from three-dimensional bulb structures to two-dimensional LED module surfaces. The LED modules are designed as flat panels that line the inner surface of the light tube, maximizing lighting output while minimizing spatial occupation compared to conventional spherical bulbs.
3Use of energy by moving object
If high-power LEDs are used in sealed natural light tubes, then energy efficiency improves, but overheating occurs that reduces service life
Solution Approach 1:
The patent introduces heat dissipation intermediaries between the LED modules and the sealed tube environment. These intermediaries include heat sinks, thermal conductive materials, and ventilation channels that facilitate heat removal from the LED components without compromising the overall sealing integrity of the light tube system.
Solution Approach 2:
The patent modifies the thermal management parameters of the LED system by adjusting operating temperatures, implementing thermal shutdown mechanisms, and using thermally conductive materials. These parameter changes enable high-power LEDs to operate efficiently while maintaining safe operating temperatures.
4Illumination intensity
If LED support body is designed with central cavity for light passage, then natural light transmission improves, but structural complexity increases
Solution Approach 1:
The patent designs the LED support body to serve multiple functions simultaneously: it provides mechanical support for LED modules, creates structural reinforcement for the light tube, and forms the central cavity for natural light transmission. This multi-functionality reduces overall structural complexity despite the added cavity feature.
Solution Approach 2:
The patent merges the support structure and light transmission function into a single integrated component. The LED support body combines mechanical support elements with the central light passage cavity, eliminating the need for separate structural reinforcements and simplifying the overall device architecture.
