Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a full-angle electronic light source is selected to achieve compatibility with different lamp housings and lighting directions, then adaptability is improved, but light pollution and energy waste increase due to extra light from non-illuminated angles
Solution Approach 1:
The patent applies the dynamics principle by making the illuminant rotatable relative to the connecting portion, and the connecting portion rotatable relative to the fixing portion. This dynamic adjustment capability allows the light source to change its luminous angle and direction according to different lamp housing requirements, while avoiding light pollution by directing light only where needed. The rotatable mechanism enables the system to adapt to various lighting directions (downward, obliquely downward, left and right, front and rear, obliquely upward) without emitting unnecessary light.
2Adaptability or versatility
If a conventional LED lotus lamp with multiple light modules is used to adjust light direction, then lighting direction flexibility is improved, but device complexity increases and light pollution prevention fails
Solution Approach 1:
The patent applies segmentation by dividing the light source into distinct functional modules: the illuminant (light-emitting component), the connecting portion (rotation mechanism), and the fixing portion (mounting interface). This segmentation allows each component to perform its specific function efficiently - the illuminant provides light, the connecting portion enables angle adjustment, and the fixing portion ensures stable installation. This modular approach reduces overall device complexity compared to using multiple complete light modules, while still achieving flexible light direction control.
3Device complexity
If the power supply is integrated with the illuminant, then device simplicity is maintained, but heat dissipation performance deteriorates
Solution Approach 1:
The patent applies the extraction principle by separating the power supply from the illuminant and placing it in a dedicated housing. This separation removes the heat-generating power supply components away from the heat-sensitive illuminant, improving heat dissipation performance. The power supply is electrically connected to the illuminant through the holder, maintaining electrical functionality while achieving thermal management. This extraction of the power supply from the illuminant assembly effectively addresses the heat dissipation issue without significantly increasing device complexity.

AI summary
A multi-angle light source device includes a holder (1), a housing (6) movably connectable with the holder and rotated relative to the holder, a power supply (8) received in the housing and electrically connected to the holder, and a body (2) fixedly connected to the housing. The body includes a fixing portion (3) connected to a proximal portion of a connecting portion (4), wherein the connection portion is configured to rotate relative to the fixing portion and at least one illuminant (5) connected to a distal portion of the connecting portion to rotate relative to the connecting portion. The present structure can flexibly adjust its luminous angle so that it can be conveniently used in different lamp-housings, suppress light pollution, reduce waste of electric energy, and further improve its heat dissipation performance of the product by the power supply separating from its heat source of each illuminant.
