Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional lamp uses a constant color temperature light source, then the lamp structure is simple, but the lamp cannot change light color to meet evolving lighting requirements
Solution Approach 1:
The patent applies the dynamics principle by making the optical device rotatable relative to the radiator. The optical device can be rotated to different angular positions (e.g., 0° for cold light, 180° for warm light), dynamically changing the light output characteristics without replacing the light source. This mechanical rotation enables the lamp to adapt to different lighting requirements while maintaining a simple overall structure.
Solution Approach 2:
The patent implements multi-functionality by designing a single optical device that can provide multiple lighting functions (cold light and warm light) through rotation. The same physical component serves different purposes at different angular positions, allowing one lamp to fulfill multiple lighting needs without requiring multiple light sources or complex electronic control systems.
2Adaptability or versatility
If a lamp allows color temperature switching, then the lighting flexibility improves, but the device complexity increases
Solution Approach 1:
The patent applies the self-service principle by designing the optical device with an integrated actuator that automatically triggers the switch when the device is rotated. The rotation motion itself activates the switching mechanism through the actuator's engagement with the switch trigger, eliminating the need for separate control buttons, sensors, or electronic switching circuits. The system serves itself by converting mechanical rotation directly into switching action.
3Ease of operation
If the optical device is made rotatable for color switching, then the user convenience improves, but the fixation stability may be compromised
Solution Approach 1:
The patent applies segmentation by dividing the fixation mechanism into distinct functional elements: the optical device, the radiator with positioning features, and the actuator with engagement features. The optical device can be easily rotated for operation, while the actuator and radiator positioning features provide stable fixation when positioned. This segmentation allows the system to achieve both ease of rotation and reliable fixation without compromising either requirement.

AI summary
The present application discloses a lamp, which comprises a housing, a radiator being provided with an accommodating space for accommodating a light source and a Printed Circuit Board (PCB) board, an optical device having a bottom surface facing towards the radiator and a top surface facing towards external space, and a switch being connected to the PCB board, wherein the optical device comprises an actuator which is cooperated with the switch, wherein the optical device is rotatably arranged relative to the radiator so that the switch is switched by the actuator. By means of such an arrangement, a user may manually rotate the optical device of the lamp to drive the switch located inside the lamp to be switched, so that the lamp is conveniently switched between different color temperatures, for example between cold light and warm light.
