Refrigerated Case Foot Adjustment for Easy Leveling Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The vertical adjustment of refrigerated display cases is often difficult to perform due to lack of accessibility and stability in existing designs.
Innovation Solution
The refrigerated display case features vertically adjustable front and rear feet with a rotating threaded bolt mechanism accessible from above, supported by C-shaped side frames and intermediate frames with internal threads, allowing easy height adjustment and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the feet are attached to the bottom assembly without accessible adjustment mechanisms, then the structure is simpler, but the vertical adjustment becomes difficult to perform
Solution Approach 1:
The adjustment mechanism is designed to be accessible from the vertical dimension (from above through the bottom assembly) rather than requiring access from the horizontal dimension (from the side or bottom). The threaded bolt extends vertically through the bottom assembly with its head accessible from above, allowing adjustment in the vertical direction without compromising structural simplicity.
Solution Approach 2:
The threaded bolt mechanism allows the feet to be adjusted using a simple tool (such as an Allen key) that can be inserted from above. The operator can perform the adjustment themselves without requiring disassembly or complex tools, making the system self-serviceable through the existing vertical access provided by the bottom assembly structure.
2Ease of operation
If the feet are made vertically adjustable with accessible mechanisms, then the ease of operation improves, but the stability of the structure may be compromised
Solution Approach 1:
The adjustment mechanism is segmented into distinct functional parts: the threaded bolt for adjustment, the nut for locking, and the foot for support. This segmentation allows the adjustment function to be isolated from the main structural load-bearing paths. The threaded bolt and nut assembly is contained within the bottom assembly structure, separating the adjustment mechanism from the critical support structure while maintaining both adjustability and stability.
Solution Approach 2:
The threaded bolt acts as an intermediary element between the adjustment operation and the foot position. By using the threaded mechanism as a mediator, the connection between the adjustment action and the foot movement is indirect and controlled, allowing precise adjustment without compromising the direct load-bearing connection between the bottom assembly and the foot. The nut serves as a locking intermediary that secures the adjusted position while maintaining structural integrity.
