Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bulb dimming and color temperature adjustment methods, such as remote controllers or silicon-controlled dimmers, are costly, prone to loss, and do not provide stepless dimming capabilities, limiting the ability to achieve gradual color changes.
Innovation Solution
A rotating bulb design that includes a lamp holder, control board, and adjustable resistor, where the rotation of the lamp body drives the resistor to generate different resistance signals, allowing for stepless dimming, brightness, and color temperature adjustments through a power management circuit and control chip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote controller is used for dimming, then dimming function is achieved, but cost increases and the controller is easy to lose
Solution Approach 1:
The patent extracts the dimming control function from the remote controller and relocates it to the lamp body itself through a rotating switch mechanism. This eliminates the need for separate remote controllers while maintaining the dimming function, thereby reducing cost and preventing loss of the controller.
Solution Approach 2:
The lamp body incorporates a rotating switch that allows users to adjust brightness directly on the lamp itself without requiring external controllers. The lamp serves its own dimming needs through an integrated control mechanism, eliminating dependency on separate devices.
2Ease of operation
If a silicon-controlled dimmer on the wall is used, then dimming is achieved, but it requires original household circuit to have a dimmer, so ordinary household circuits cannot meet the requirement
Solution Approach 1:
The patent extracts the dimming control functionality from the household circuit infrastructure and embeds it within the lamp body. This eliminates the requirement for pre-installed dimmer switches in walls or on circuits, allowing the lamp to function with ordinary household wiring.
Solution Approach 2:
The lamp is designed with an integrated rotating switch that works with standard household circuits without requiring special circuit modifications. This universal design allows the lamp to provide dimming functionality in any ordinary household setting without needing pre-installed dimmer infrastructure.
3Ease of operation
If a lever on the lamp body is added for adjustment, then dimming and color temperature adjustment are achieved in different stages and different gears, but stepless dimming for gradual color change cannot be achieved
Solution Approach 1:
The patent replaces discrete lever adjustments with a continuous rotating switch mechanism. This dynamic control allows the user to rotate the switch smoothly to any position, achieving stepless dimming and gradual color temperature changes rather than fixed discrete stages.
Solution Approach 2:
The rotating switch continuously varies the resistance value, enabling smooth transitions in brightness and color temperature. This continuous parameter adjustment replaces the discrete gear-based adjustment, achieving precise stepless control for gradual color changes.
4Device complexity
If only a few gears can be selected, then the adjustment mechanism is simple, but the lighting effects are limited
Solution Approach 1:
The rotating switch provides continuous adjustment capability, transforming the static gear-based system into a dynamic control mechanism. This allows infinite positioning options for brightness and color temperature, greatly expanding lighting effects while maintaining a simple rotational interface.
