Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tilt sensors require laborious alignment and additional equipment for commissioning, especially when detecting tilt in multiple axes, and often rely on expensive hardware and complex measurement tools for zero position indication.
Innovation Solution
A tilt sensor with an optical indication device using a single light source to transmit distinct signals for zero position and deviation, providing quantitative information about the extent of deviation, allowing for easy alignment and eliminating the need for additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tilt sensors output zero position via electronic analogue signals, then measurement precision is improved, but device complexity and ease of operation deteriorate due to requiring special measuring equipment and serial communication hardware
Solution Approach 1:
The patent replaces electronic analogue signals and serial communication hardware with an optical indication means (LED) that directly visually indicates the zero position. This substitution eliminates the need for complex measurement equipment and serial communication interfaces, thereby reducing device complexity while maintaining measurement precision.
Solution Approach 2:
The tilt sensor performs self-indication of its zero position through the optical means integrated within the device itself, without requiring external measuring equipment or additional hardware. The device serves its own indication needs, simplifying the overall system.
2Loss of information
If tilt sensors use multiple light sources for bar chart display, then information completeness is improved, but device complexity and cost increase
Solution Approach 1:
The patent segments the information transmission by using different temporal patterns (continuous vs. alternating on/off) of a single light source to convey different types of information. This segmentation allows complete information transmission without requiring multiple simultaneous light sources, thereby reducing device complexity.
Solution Approach 2:
The patent employs periodic action by alternating the light source between on and off states to encode deviation information. The frequency and pattern of these periodic transitions convey the extent of deviation from zero position, enabling complete information communication with a single light source rather than multiple static indicators.
