Cooling box and analysis device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cooling boxes with a drawer structure, the slide rail is typically disposed inside the cooling space, which reduces cooling efficiency and can lead to deformation and breakage of the bridging part when a load exceeding the weight of the bridged article is applied.
Innovation Solution
The cooling box design includes a heat insulating box body with a nozzle insertion hole and a sliding member holder with a sliding member that contacts the bridging part, allowing the bridging part to slide and come into surface contact with the sliding member holder when a load is applied, preventing deformation and breakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slide rail is disposed inside the cooling space, then the cooling box structure is compact, but the cooling efficiency is reduced and the bridging part may deform or break under load
Solution Approach 1:
The slide rail is extracted from the cooling space and disposed outside, separating the mechanical support function from the thermal environment. This reduces the heat capacity inside the cooling space and improves cooling efficiency, while the bridging part remains protected outside the cooled region.
Solution Approach 2:
The slide rail is repositioned from a three-dimensional location inside the cooling space to a two-dimensional location on the outer surface of the cooling box. This spatial reconfiguration maintains structural support while eliminating the thermal loading issue.
2Loss of energy
If the slide rail is disposed outside the cooling space, then cooling efficiency is improved, but the bridging part may deform or break when load is applied due to cantilever structure
Solution Approach 1:
The slide rail is merged with the drawer door structure, creating an integrated assembly where the slide rail serves as both the support structure and the moving component. This eliminates the cantilever effect by providing direct support from the drawer door.
Solution Approach 2:
The drawer door is given multiple functions: it serves as both the access door and as the support structure for the slide rail. This multi-functionality allows the slide rail to be positioned outside the cooling space while maintaining structural integrity through the drawer door's support.
3Reliability
If the same number of aspiration nozzles as reagent containers are provided, then contamination is prevented, but the load for breaking through the film increases
Solution Approach 1:
The aspiration nozzles are extracted from the drawer door structure and positioned separately, allowing them to apply force directly to the reagent containers without transmitting the breaking force to the bridging part. This separates the contamination prevention function from the structural load path.

AI summary
This cooling box for storing reagents and the like in a cold state, becomes a cantilever structure where, when a slide rail is disposed outside a cooling space, an installation part is held only by a drawer door. When a heavy article is placed, the installation part is deformed and broken. This cooing box includes a sliding member holder provided with sliding members each including a compression coil spring, which is an elastic body inside a heat insulating box body. When a reagent container is installed in the installation part and drawn out, the installation part and the sliding members slide in contact with each other. When a load exceeding the weight of an installed article is applied to the installation part, the installation part and the sliding member holder come into surface contact with each other. Thus, deformation and breakage of the installation part can be prevented.
