Rotating Body Inspection with Linear Sensor Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotating body inspection apparatuses for electrification components require a sub sprocket with a diameter larger than the main sprocket to prevent overlapping of sensors, leading to increased size, manufacturing costs, and reduced speed of the main sprocket, and necessitate new sub sprockets when rotation angles change.
Innovation Solution
A rotating body inspection apparatus with a sub sprocket diameter smaller than the main sprocket, utilizing a linear conversion portion to house an origin sensor and position limit sensor, allowing for miniaturization and high-speed rotation, and adjustable sensor positions to accommodate varying rotation angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the diameter of the sub sprocket is increased to prevent sensor overlapping, then the sensor overlapping problem is resolved, but the apparatus size increases and manufacturing cost increases
Solution Approach 1:
The patent makes the sub sprocket diameter variable rather than fixed. The diameter is dynamically adjusted based on the rotation angle requirement, allowing the system to optimize between sensor detection accuracy and apparatus size for different inspection scenarios
Solution Approach 2:
The patent changes the physical parameter of the sub sprocket diameter to resolve the contradiction. By making the diameter adjustable rather than fixed, the system can adapt to different rotation angles while preventing sensor overlapping, thus resolving both the reliability and size concerns
2Reliability
If the diameter of the sub sprocket is increased to prevent sensor overlapping, then the sensor overlapping problem is resolved, but the rotation speed decreases
Solution Approach 1:
The patent dynamically adjusts the sub sprocket diameter based on the required rotation angle. For high-speed rotation scenarios, a smaller diameter is used, while for scenarios requiring greater rotation angles, the diameter is increased to prevent sensor overlapping, thus optimizing both speed and reliability
Solution Approach 2:
By changing the sub sprocket diameter parameter dynamically, the system resolves the contradiction between detection accuracy and rotation speed. The diameter is optimized for each specific operation scenario, allowing high-speed rotation when possible while ensuring sensor reliability when needed
3Adaptability or versatility
If a new sub sprocket is manufactured for varying rotation angles, then the rotation angle requirement is met, but the manufacturing cost increases
Solution Approach 1:
The patent implements a dynamically adjustable sub sprocket diameter mechanism that can be changed without manufacturing new components. This allows the system to adapt to different rotation angle requirements while using the same physical sub sprocket, significantly reducing manufacturing costs
Solution Approach 2:
The patent makes a single sub sprocket serve multiple functions by allowing its diameter to be adjusted. This universal design eliminates the need for multiple specialized sub sprockets for different rotation angles, reducing manufacturing complexity and cost while maintaining adaptability
