Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external control devices (PWM signal, 0-10V voltage signal, silicon-controlled switch) are integrated into the lamp circuit to adjust luminous power, then the ability to adjust luminous intensity is improved, but the production complexity increases and production efficiency decreases
Solution Approach 1:
The patent extracts the control function from complex integrated circuits and implements it through a simple resistance control device with a potentiometer. The resistance control device is connected in series with the lamp bulb, allowing luminous power adjustment through simple resistance change without integrating complex control circuits into the lamp, thus reducing production complexity while maintaining ease of operation
Solution Approach 2:
The patent introduces a resistance control device as an intermediary component between the power source and the lamp. This mediator (resistance control device) simplifies the control mechanism by using a potentiometer to adjust resistance, thereby controlling luminous power without requiring complex integrated control circuits, reducing both device complexity and production difficulty
2Ease of operation
If complex control circuits are integrated into the lamp to enable luminous power adjustment, then the luminous intensity control capability is improved, but the production efficiency deteriorates
Solution Approach 1:
The patent extracts the luminous intensity control function from complex integrated control circuits and implements it through a simple resistance control device with potentiometer. This extraction simplifies the control mechanism to basic resistance adjustment, making the lamp easier to produce while maintaining luminous intensity control capability
Solution Approach 2:
Instead of integrating control circuits into the lamp (conventional approach), the patent inverts the approach by using a separate, simple resistance control device connected in series. This inversion simplifies the lamp structure and production process while still achieving luminous intensity control, thereby improving production efficiency
3Ease of operation
If traditional dimming control methods are used, then luminous power adjustment is achieved, but the user cannot intuitively view the working power of the lamp
Solution Approach 1:
The patent uses color changes of the indicator light to represent different working power states of the lamp. The indicator light displays different colors corresponding to different luminous power levels, providing intuitive visual feedback to users about the current working power without requiring complex displays or additional information channels

AI summary
A resistance control device and its lamp. The resistance control device includes: a shell, which is provided with an accommodating chamber and the first opening and the second opening connecting the accommodating chamber; and a control module, which includes the resistor and the external plug in the accommodating chamber. The external plug is electrically connected to the resistor. One end of the external plug is set extending the first opening. The external plug is used to connect the resistor to the lamp; and a boosting part, which is connected to the resistor and exposed in the second opening. The boosting part is used to twist or toggle the resistor to adjust the resistance value of the resistor accessing to the lamp. The resistance control device can be removed to achieve the quick separation and assembly of the lamp and improve the use convenience.
