Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional waterproof lamps have limited functionality, requiring multiple types for different application scenarios and high costs due to fixed adjustment components that cannot be accessed without detachment, compromising user convenience and waterproof performance.
Innovation Solution
A waterproof lamp design with a switch and operation knob on the exterior, allowing adjustment of correlated color temperature (CCT) and power through a rotating mechanism, integrated with a sealing system to maintain waterproof integrity, and featuring a heat dissipation cup for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adjustment components are arranged at the base of the waterproof lamp to maintain waterproof performance, then waterproof performance is improved, but ease of operation deteriorates as users must detach the lamp to perform adjustments
Solution Approach 1:
The adjustment mechanism is segmented into two parts: the switch with switching gears is mounted inside the waterproof lamp housing, while the operation knob is positioned outside the housing. This segmentation allows the waterproof lamp to maintain its sealed structure while providing external access for adjustment operations through the through hole in the housing wall.
Solution Approach 2:
The operation knob acts as an intermediary element that bridges the internal switch mechanism and the external user interface. The knob transmits rotational motion through the through hole to drive the switching gears, enabling users to adjust brightness and CCT without compromising the waterproof seal of the lamp housing.
2Device complexity
If a single waterproof lamp design is used for all application scenarios, then device complexity is reduced, but adaptability deteriorates as different scenarios require different brightness and CCT adjustments
Solution Approach 1:
The lamp incorporates dynamic adjustment capabilities through the rotary switch with multiple switching gears, allowing the brightness and correlated color temperature to be dynamically changed according to different application scenarios. The operation knob enables smooth rotation through multiple gear positions, providing versatile lighting control from a single device.
Solution Approach 2:
The waterproof lamp is designed with multi-functionality by integrating a rotary switch that can select different switching gears, enabling a single device to serve multiple application scenarios. Users can adjust both brightness and CCT according to specific needs, making the lamp universally applicable for various lighting requirements without needing multiple specialized lamps.
3Adaptability or versatility
If multiple waterproof lamps are used for different application scenarios, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The patent implements a universal waterproof lamp design with a rotary switch mechanism that can accommodate multiple switching gears, allowing a single manufactured product to serve multiple application scenarios. This eliminates the need to manufacture separate lamps for different purposes, thereby reducing overall manufacturing costs while maintaining high adaptability.
Solution Approach 2:
The lamp achieves versatility through parameter changes in the switching mechanism, where the rotary switch can select different switching gears to change the electrical connection parameters. This allows the same physical device to provide different lighting output characteristics (brightness and CCT) by changing the electrical parameters, avoiding the need for multiple devices with different fixed parameters.
