Control Circuit Device for Wearable Lighting Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control circuit devices for wearable devices, such as shoes, are overly sensitive to vibrations, causing unnecessary power drain as they emit light even when not in use, due to the vibration detector's sensitivity.
Innovation Solution
A control circuit device comprising a lighting unit, a battery, an insulating sheet, a triggering slice, and a control module with a first and second control unit, where the second control unit can be switched on or off by physically contacting the battery, allowing users to control when the device emits light, thereby preventing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vibration detector is made highly sensitive to detect vibration, then the device can detect vibration from actions like walking, running, or jumping, but it will also detect slight vibrations from other activities and cause unnecessary power drain
Solution Approach 1:
The patent introduces a trigger switch as an intermediary component between the vibration detector and the lighting unit. This trigger switch acts as a mediator that receives the vibration detection signal and conditions the activation of the lighting unit, allowing the system to distinguish between genuine motion events and spurious vibrations, thereby preventing unnecessary power consumption while maintaining sensitive vibration detection capability
Solution Approach 2:
The control system is segmented into distinct functional modules: a vibration detector for sensing, a trigger switch for conditional activation, and a lighting unit for output. This segmentation allows each component to perform its specific function independently, with the trigger switch serving as a gatekeeper that prevents the lighting unit from activating due to false vibration signals, thus resolving the contradiction between detection sensitivity and power consumption
2Productivity
If the LEDs are controlled to emit light frequently in response to detected vibrations, then the device provides continuous light patterns for various activities, but the battery power is depleted quickly
Solution Approach 1:
The trigger switch enables periodic or conditional activation of the lighting unit based on genuine user intent rather than continuous operation. By requiring a deliberate trigger action, the system transforms continuous potential light emission into discrete, purposeful lighting events, thereby extending battery life while maintaining high productivity during actual use periods
3Adaptability or versatility
If the vibration detector is set to a low threshold for activation, then the device responds to even slight vibrations, but it causes power drain by emitting light when not necessary
Solution Approach 1:
The system dynamically adjusts its response characteristics through the trigger switch mechanism. Rather than using a fixed low threshold that causes false activation, the trigger switch creates a dynamic activation condition that adapts to genuine user needs, allowing the system to maintain high adaptability and responsiveness while preventing unnecessary power consumption from spurious activation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively manages power usage by allowing users to activate the lighting only when needed, reducing unnecessary power drain and extending battery life.
Implementation Method 1
an insulating sheet, where the insulating sheet is configured on the first electrode of the battery and forms an opening to expose part of the first electrode of the battery
Implementation Method 2
The triggering slice has a fixed portion and a contact portion. The fixed portion is configured on the insulating sheet, and the contact portion is configured on the opening of the insulating sheet

AI summary
A control circuit device includes a lighting unit, a battery, an insulating sheet, a triggering slice, and a control module. The insulating sheet is configured on a first electrode of the battery and forms an opening. A fixed portion of the triggering slice is configured on the insulating sheet, while a contact portion of the triggering slice extends to the opening to make contact with the first electrode through the opening by pressing the triggering slice. A first control unit of the control module is connected to the first electrode and second electrode of the battery, and the light unit to receive electric power from the battery and control when the light unit emits light. A second control unit of the control module is connected to the triggering slice, the second electrode, and the first control unit to receive power when the triggering slice is made in contact with the first electrode to switch on or off the first control unit.
