Sensor Apparatus Symmetrical Mounting Reduces Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor apparatuses with multiple sensor sets have a complex structure and increased part count, leading to potential position misalignment and increased size due to separate sensor arrangement parts, which complicates installation and reduces accuracy.
Innovation Solution
A sensor apparatus with a common sensor arrangement part that houses multiple identical sensor sets symmetrically arranged around a center of gravity, reducing the number of parts, eliminating gaps between sensor sets, and minimizing position misalignment, while incorporating recessed parts to reduce the size and protrusion of sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate sensor arrangement parts are provided for multiple sensor sets, then each sensor set can be independently arranged, but the number of parts increases and the structure becomes complicated
Solution Approach 1:
Multiple sensor sets are arranged on a single common sensor arrangement part instead of using separate arrangement parts for each sensor set. This merging approach reduces the total number of parts and simplifies the overall structure while maintaining the functionality of multiple sensor sets through symmetric arrangement around the center of gravity.
2Reliability
If separate sensor arrangement parts are provided for multiple sensor sets, then each sensor set can be independently arranged, but the installation area increases due to necessary gaps between parts
Solution Approach 1:
By combining multiple sensor sets onto one common arrangement part, the gaps that would necessarily exist between separate parts are eliminated. This allows the sensor sets to be arranged closer together, reducing the total installation area while maintaining proper spacing through symmetric positioning.
3Ease of manufacture
If separate sensor arrangement parts are provided for multiple sensor sets, then each part can be independently manufactured, but position misalignment occurs between the parts
Solution Approach 1:
Multiple sensor sets are integrated onto a single common sensor arrangement part, eliminating the interfaces between separate parts. This ensures that all sensor sets share the same reference frame and center of gravity, preventing position misalignment issues that would occur with multiple separate parts while still allowing modular sensor assembly.
4Device complexity
If multiple sensor sets are arranged on a common sensor arrangement part, then the number of parts is reduced, but the sensors protrude more from the arrangement part
Solution Approach 1:
The sensor arrangement part includes recessed portions that receive and accommodate the sensors, allowing the sensors to be nested within or close to the surface of the arrangement part. This reduces the protrusion length of sensors while maintaining their functional positioning for multiple sensor sets arranged symmetrically.
