Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices, such as detectors, face challenges in manually adjusting parameters and operating modes without compromising their sealing integrity, often requiring openings in the casing and complex assembly processes.
Innovation Solution
A non-contact adjustment mechanism using sensors and a rotating adjustment ring with a permanent magnet, allowing for axial and rotational positioning to configure parameters and modes without opening the casing, utilizing sensors to send signals for parameter adjustments and mode changes, and incorporating locking mechanisms for secure settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional setting buttons are used to manually adjust parameters, then ease of operation is improved, but device complexity and manufacturing cost increase due to requiring separate buttons, magnets, and openings in the casing
Solution Approach 1:
The patent merges the adjustment function directly into the casing by integrating magnets and sensors into the casing structure itself, eliminating the need for separate adjustment buttons. The casing serves both as the housing and as the adjustment mechanism carrier, reducing overall device complexity while maintaining ease of operation.
Solution Approach 2:
The casing is designed to serve multiple functions: it provides structural housing, contains the adjustment mechanism (magnets and sensors), and maintains device sealing. This multi-functionality eliminates the need for separate adjustment components, reducing device complexity while preserving ease of operation.
2Ease of operation
If openings are formed in the casing to accommodate adjustment buttons, then ease of operation is improved, but sealing integrity deteriorates requiring additional sealing components like O-rings and resin injection
Solution Approach 1:
The patent extracts the adjustment mechanism from the external environment and integrates it completely within the sealed casing. Magnets and sensors are positioned inside the casing, allowing parameter adjustment without creating openings that would compromise sealing integrity.
Solution Approach 2:
The patent uses magnetic field as an intermediary to transmit adjustment signals through the sealed casing wall. The magnets interact with sensors through the casing material without requiring physical openings, maintaining sealing integrity while enabling ease of operation.
3Ease of operation
If separate adjustment buttons with magnets are used, then ease of operation is improved, but manufacturing cost increases due to additional assembly steps and multiple components
Solution Approach 1:
The patent combines multiple components (casing, magnets, sensors, adjustment mechanism) into an integrated structure where the casing itself carries the adjustment function. This merging eliminates separate assembly steps for installing adjustment buttons and reduces the total number of components, improving ease of manufacture while maintaining ease of operation.
4Measurement precision
If multiple sensors and magnets are used for adjustment, then measurement precision is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent positions sensors and magnets at specific locations within the casing to detect and respond to adjustment inputs. By strategically placing these components only where needed for parameter detection, the patent achieves measurement precision while minimizing the total number of components and reducing device complexity.
