Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid level verification devices lack an integral source of illumination that is activated by motion detection, requiring either continuous activation or manual switching, which is inefficient and inconvenient, especially in dark environments.
Innovation Solution
A fluid level verification apparatus with an integrated light source, such as a light emitting diode (LED), activated by a motion sensor that detects the presence of a foreign body, including a power source and electronics assembly for controlled illumination, ensuring the light turns on and off accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a separate backlighting illumination apparatus is used, then illumination of fluid level gauge is achieved, but device complexity increases
Solution Approach 1:
The patent integrates the light source directly into the fluid level gauge assembly, combining the illumination function with the gauge structure. This eliminates the need for separate backlighting apparatus and reduces overall device complexity while maintaining effective illumination of the fluid level indication.
2Illumination intensity
If light source is continuously activated, then visibility of fluid level is improved, but energy consumption increases
Solution Approach 1:
The patent employs a motion-activated sensor that triggers the light source only when movement is detected near the gauge. This periodic activation based on sensor input provides illumination exactly when needed for visibility while minimizing energy consumption by keeping the light off during periods of no activity.
Solution Approach 2:
The motion sensor automatically detects when a user approaches and activates the light source without manual intervention. The system serves itself by using environmental cues (motion detection) to control illumination, eliminating the need for continuous power while ensuring visibility when required.
3Ease of operation
If manual switching mechanism is used, then control of illumination is achieved, but ease of operation decreases
Solution Approach 1:
The patent replaces manual mechanical switching with an automatic motion sensor system. The sensor detects motion and electronically controls the light source activation, substituting the mechanical switch with an automated sensing and control system that improves ease of operation while managing device complexity through integration.
