Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional floodlights use fixed lamp and lamp post connection, then installation is simple, but irradiation angle cannot be adjusted
Solution Approach 1:
The floodlight is divided into modular components: lamp head, rotating assembly, mounting rack, and heat dissipation components. The rotating assembly includes a connecting pipe with rotating seats at both ends, allowing the lamp head to be segmented and rotated independently to adjust irradiation angles without complicating the overall structure.
Solution Approach 2:
The fixed connection between lamp and lamp post is replaced with a dynamic rotating mechanism. The connecting pipe allows the lamp head to rotate to different angles, and the buckling cover with pin-jointed surface enables flexible positioning. This dynamic structure resolves the contradiction by providing adjustability while maintaining structural simplicity through standardized rotating components.
2Use of energy by moving object
If conventional floodlights use high-pressure sodium lamp or metal halide lamp, then illumination intensity is high, but energy consumption is high and heat generation is large
Solution Approach 1:
The patent changes the fundamental parameter of light source technology from conventional high-pressure discharge lamps to LED modules. LED technology provides superior energy efficiency with significantly lower power consumption while maintaining high illumination intensity. The modular LED design with integrated heat dissipation components further optimizes energy utilization by directing more energy into light output rather than waste heat.
3Object-affected harmful factors
If conventional floodlights use high-pressure sodium lamp or metal halide lamp, then illumination is achieved, but mercury vapor causes environmental pollution
Solution Approach 1:
The patent eliminates the harmful mercury vapor source by replacing conventional discharge lamps with LED technology. This substitution not only removes the environmental pollution issue but also extends service life. The LED modules combined with efficient heat dissipation components create a reliable, long-lasting lighting solution that is environmentally friendly, directly resolving both the pollution and reliability concerns.
4Temperature
If conventional floodlights generate large amount of heat, then illumination is produced, but lamp body size becomes large and appearance is unaesthetic
Solution Approach 1:
The patent extracts and separates the heat dissipation function from the lamp body structure. Independent heat dissipation components are designed with dedicated heat dissipation fins and airflow channels, removing excess heat before it can increase lamp body temperature or expand the lamp housing. This extraction approach allows for a compact, aesthetically pleasing lamp design while effectively managing thermal energy.

AI summary
The present invention provides a floodlight, including a mounting rack, a power source module, a rotating assembly, buckling covers, several heat dissipation components, and an LED module, where the rotating assembly includes a connecting pipe and rotating seats; the heat dissipation component includes a heat dissipation body and a gear cover; an abutment surface is disposed on a top surface of the rotating seat; a pin-jointed surface is disposed on a bottom surface of the buckling cover; and two ends of the mounting rack are respectively clamped to rotating seats and then are pin-jointed to the buckling covers, to adjust an irradiation angle of the floodlight. The foregoing floodlight has a simple structure, a small size, and an adjustable irradiation angle. The connecting pipe is connected to the heat dissipation body and the gear cover to implement modular assembly of the multiple heat dissipation components, so that an overall size of the heat dissipation components is small; an annular clamping tooth paired with the rotating seat is disposed on the gear cover, for fixed installation of the mounting rack, so that it is very convenient for site operation personnel to adjust an angle of the floodlight; and there are multiple installation directions on the mounting rack, to satisfy installation requirements of the floodlight in a variety of occasions, thereby making the floodlight have relatively high practicability.
