Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems fail to accurately adjust brightness based on external signals, leading to inadequate illumination when sensing signals are too strong or weak, resulting in users not perceiving changes in the signal.
Innovation Solution
A signal balance system comprising a signal detecting module and a processing module that adjusts the sensing signal by determining if it exceeds thresholds, decreasing or increasing the signal to control the lighting unit's brightness effectively, ensuring the lighting unit reflects the external audio signal accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sensor directly controls the lighting unit based on the sensing signal, then the control system is simple, but the lighting unit cannot accurately reflect the sensing signal when the signal is too strong or too weak
Solution Approach 1:
The patent introduces a processing module as an intermediary between the sensor and lighting unit. This module receives the sensing signal, compares it with threshold values, and generates an adjusted control signal. When the sensing signal is too strong or too weak, the processing module intervenes to adjust the signal level, ensuring the lighting unit accurately reflects the intended brightness level while maintaining system simplicity.
2Area of stationary object
If the lighting unit has a small reaction region, then the device size is reduced, but the lighting unit will not illuminate correspondingly when the sensing signal is too strong or too weak
Solution Approach 1:
The patent changes the parameter of the control signal by introducing threshold-based adjustment. The processing module compares the sensing signal with predefined threshold values and adjusts the control signal parameters accordingly. This allows the compact lighting unit to reliably illuminate across a wider range of sensing signal strengths without increasing its physical reaction region.
3Productivity
If the sensing signal is not adjusted when exceeding thresholds, then the control process is simple, but the lighting unit cannot truly reflect the sensing signal causing user perception issues
Solution Approach 1:
The patent implements a feedback mechanism where the processing module continuously monitors the sensing signal against threshold values and adjusts the control signal accordingly. This feedback loop ensures that when the sensing signal exceeds threshold values, the processing module detects this condition and adjusts the control signal to maintain accurate signal reflection, preventing information loss while maintaining efficient processing.

AI summary
A signal balance system, a light control system, and a signal balance method thereof are disclosed. The signal balance system includes a signal sensing module and a processing module. The signal sensing module is used for detecting an external signal source to generate a sensing signal. The processing module is used for generating an adjusting signal based on the sensing signal, wherein the processing module determines whether the sensing signal exceeds a first threshold; if yes, the processing module decreases the sensing signal to generate the adjusting signal so as to control a controlled device.
