Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the whole tubular lamp is made of plastic with light plate secured inside, then pressure resistance is high and safety performance is good, but heat dissipation effect is poor and service life is short
Solution Approach 1:
The patent employs composite material construction by combining plastic for the light cover (providing pressure resistance and safety) with aluminum alloy for the heat dissipation housing (providing thermal conductivity). This composite approach allows each material to perform its optimal function - the plastic cover maintains structural integrity while the aluminum housing efficiently dissipates heat from the LED light plate, thereby resolving the contradiction between pressure resistance and heat dissipation effect.
2Illumination intensity
If conventional LED tubular lamp structure is used, then light emission is achieved, but structure is too complex and disassembly is too difficult
Solution Approach 1:
The patent divides the tubular lamp into distinct modular segments: the light cover assembly, the heat dissipation housing with integrated driver, the LED light plate, and end caps. Each segment is designed as an independent unit that can be easily assembled and disassembled. The light cover can be removed to access the light plate for replacement, and the driver is integrated into the housing as a separate module, thereby simplifying the overall structure while maintaining light emission functionality and enabling easy maintenance.
3Area of stationary object
If LED plate is made in large size, then light coverage is improved, but heat dissipation becomes more difficult in plastic housing
Solution Approach 1:
The patent utilizes composite material construction where the heat dissipation housing is made of aluminum alloy instead of plastic. This allows the LED light plate to be made in large size for improved light coverage while the aluminum housing provides efficient thermal conductivity to dissipate the increased heat load from the larger light plate, thereby resolving the contradiction between light plate size and heat dissipation capability.
