Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for altering the state of a light on a peripheral device, such as a keyboard, require user input or continuous detection, leading to inefficiency and potential eye strain due to inconsistent ambient light adjustments.
Innovation Solution
A method that automatically adjusts the state of a peripheral device's light based on outputs from proximity and ambient light sensors, using threshold values to determine when to turn the light on, off, or adjust its intensity, without user input, utilizing a computer driver and processor to execute these adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If detectors are always on or dependent on user inputs to alter light state, then the light can be adjusted based on ambient conditions, but power consumption increases and user focus is disrupted
Solution Approach 1:
The system uses periodic polling of sensor data at predetermined time intervals instead of continuous detection. The processor receives sensor outputs, compares them to threshold values, and alters light state only when changes exceed thresholds, creating a periodic check mechanism that reduces power consumption while maintaining adaptability.
Solution Approach 2:
The system automatically adjusts light state based on sensor comparisons without requiring user input. The processor autonomously determines when to alter light state by comparing sensor outputs to threshold values, enabling the system to serve itself and eliminate the need for user-triggered detections.
2Adaptability or versatility
If detectors are always on or dependent on user inputs, then light adjustment is possible, but eye strain occurs due to inconsistent ambient light adjustments
Solution Approach 1:
The system continuously monitors ambient light conditions through sensors and provides feedback to the processor. The processor compares sensor outputs to threshold values and automatically adjusts light state when changes are detected, creating a closed-loop feedback system that ensures consistent ambient light adjustment and prevents eye strain.
Solution Approach 2:
The system proactively adjusts light state before user needs arise by continuously monitoring ambient conditions. By comparing sensor outputs to threshold values in advance, the system prepares optimal lighting conditions, preventing eye strain before it occurs rather than reacting after the problem arises.
3Use of energy by moving object
If automatic threshold-based control is implemented, then power usage is optimized and eye strain is reduced, but device complexity increases
Solution Approach 1:
The system uses threshold values as parameters to automatically determine when light state should change. By comparing sensor outputs against predetermined threshold values, the system implements automatic control logic that optimizes power usage and reduces complexity compared to continuous monitoring or user-input-dependent systems.
