Solution Overview
Problem
Existing heating clothing devices lack control over indicator lights, which affects their appearance, especially in different environments, as they cannot adjust the display status according to the wearer's surroundings.
Innovation Solution
A heating control circuit with an indicator light button circuit that allows the main controller to control the on/off and lighting modes of indicator lights, connected to a buck circuit for voltage regulation and including field effect transistors and specific chips for precise control, enabling the wearer to manage the indicator lights based on environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If indicator lights are equipped on the heating device controller, then the wearer can clearly understand the current working status, but the heating device has a greater impact on the appearance of the external heating clothing
Solution Approach 1:
The indicator light system is made dynamically controllable through a dedicated control circuit that allows the wearer to turn the indicator lights on or off based on environmental conditions. This dynamic control resolves the contradiction by allowing the indicator lights to be visible when needed for status information and hidden when they would negatively impact the appearance of the heating clothing.
Solution Approach 2:
The indicator light control function is extracted as a separate controllable module with its own control circuit, independent from the heating control functions. This allows the indicator lights to be managed separately from the heating elements, enabling the wearer to disable the indicator lights in situations where appearance is prioritized while maintaining heating functionality.
2Loss of information
If indicator lights are always on to show working status, then the wearer can clearly understand the current working status, but the indicator lights cannot be adjusted according to the current environment
Solution Approach 1:
The indicator light system transitions from a static always-on state to a dynamic controllable state. The control circuit receives wearer input and environmental signals to dynamically adjust indicator light operation, allowing the system to adapt to different environments such as daytime versus nighttime, or indoor versus outdoor settings.
Solution Approach 2:
The system incorporates feedback mechanisms where the control circuit monitors both the wearer's control inputs and environmental conditions to automatically or manually adjust indicator light status. This feedback loop enables the system to adapt its behavior based on real-time conditions, resolving the contradiction between continuous status indication and environmental adaptability.
