Rotating Reagent Jacket Scraper for Dew Condensation Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic analysis devices face issues with dew condensation on reagent storage cabinets, leading to mold generation and reduced analysis accuracy, and the constant contact of elastic members with the inner wall results in rapid wear and frequent replacement.
Innovation Solution
The device incorporates a sliding contact mechanism with a scraper that can be manually or automatically switched to contact or retract from the inner wall of the reagent storage cabinet, utilizing the reagent jacket's rotation to remove dew condensation water, thereby reducing wear and extending the scraper's lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the elastic member is constantly in contact with the inner wall of the reagent storage cabinet to remove dew condensation water, then dew condensation water is effectively removed, but the elastic member wears quickly and requires frequent replacement
Solution Approach 1:
The patent applies the dynamics principle by making the contact member movable rather than stationary. The contact member can move between a contact state (where it removes dew condensation) and a retracted state (where it reduces wear). This is achieved through a driving mechanism that adjusts the contact member's position based on operational conditions, resolving the contradiction between maintaining effective dew condensation removal and extending the member's service life by reducing constant frictional contact
Solution Approach 2:
The patent implements periodic action by having the contact member alternately contact and retract from the inner wall. Instead of continuous contact, the system periodically engages the contact member to remove dew condensation when needed (such as during temperature changes or humidity increases) and periodically retracts it to minimize wear during normal operation. This periodic engagement-disengagement cycle extends the elastic member's lifespan while maintaining dew condensation removal effectiveness when required
2Reliability
If manual wiping of dew condensation water is performed, then mold generation is prevented, but time and labor are required
Solution Approach 1:
The patent applies the self-service principle by implementing an automatic dew condensation removal system that operates without human intervention. The contact member is automatically driven to contact the inner wall and remove dew condensation water based on sensor inputs or predetermined schedules. This automation eliminates the need for manual wiping operations, preventing mold generation while saving significant time and labor resources that would otherwise be required for regular manual maintenance

Function Achieved in This Case
The mechanism effectively removes dew condensation water while minimizing scraper wear, enhancing operational efficiency and reducing maintenance needs.
Implementation Method 1
utilizing the reagent jacket's rotation to remove dew condensation water
Implementation Method 2
By cooling an inner wall of the reagent storage cabinet, inside air is cooled by a heat transfer effect and the reagent is cooled, and at this time, dew condensation occurs due to a temperature difference between the inside air and the inner wall
