Laboratory Shaker External Pivoting Door for Easier Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laboratory shakers face challenges in maintaining cleanliness and safety during maintenance and cleaning due to the internal placement of door kinematics, which increases contamination risk and complicates access to chamber components.
Innovation Solution
The laboratory device features an externally mounted swing door mechanism with a spring-assisted opening and a design that keeps pivot arms outside the chamber, allowing for easier cleaning and reduced contamination risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door pivoting mechanism is mounted inside the chamber, then the door can be closed effectively, but the complexity of cleaning and maintenance increases due to difficult access to internal components
Solution Approach 1:
The patent extracts the door pivoting mechanism from the chamber interior and relocates it to the exterior. The pivot arms are mounted on the outer surface of the chamber wall, allowing the door to pivot externally. This extraction resolves the contradiction by maintaining effective door closure while enabling easy access to the pivoting mechanism for cleaning and maintenance without requiring entry into the chamber.
2Device complexity
If the pivoting mechanism is enclosed within the chamber, then the door structure is compact, but contamination risk increases due to difficulty in cleaning internal surfaces
Solution Approach 1:
By extracting the pivoting mechanism from the chamber interior and mounting it on the outer surface, the patent eliminates the creation of difficult-to-clean internal contours. The door structure remains compact in its closed position, but the pivoting components are now accessible from the exterior, significantly reducing contamination risk by enabling thorough cleaning without chamber entry.
3Device complexity
If the pivot arms are mounted inside the chamber, then the door mechanism is compact, but cleaning effort and time increase due to need for chamber entry
Solution Approach 1:
The patent extracts the pivot arms from the chamber interior and relocates them to the exterior surface. This arrangement maintains a compact door mechanism when closed, but crucially allows cleaning personnel to access and clean the pivoting components from the outside, eliminating the time-consuming requirement to enter the chamber for maintenance activities.
4Ease of repair
If maintenance work is performed inside the chamber, then the door mechanism can be serviced, but the risk of additional contamination increases
Solution Approach 1:
By extracting the door pivoting mechanism from the chamber interior and mounting it on the exterior, the patent enables maintenance and servicing to be performed outside the chamber. This resolves the contradiction by providing easy access to the door mechanism for repair while eliminating the contamination risk associated with opening the chamber and exposing samples to the external environment during maintenance activities.
