Refrigerated sales cabinet
Solution Overview
Problem
Wide and fully loaded refrigerated sales furniture often sag, compromising appearance and cooling efficiency, and existing solutions for plug-in units do not reliably prevent this sagging, which can lead to deformation or damage.
Innovation Solution
A refrigerated sales furniture design featuring a machine unit space below the refrigerated sales space with an intermediate support extending downwardly between side walls, a movable machine unit support plate with an elongate opening, and laterally extending guiding and support projections to prevent sagging and enhance stability, allowing for easy service access without altering the machine unit dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If an intermediate support is added to prevent sagging, then stability is improved, but device complexity increases
Solution Approach 1:
The support structure is segmented into multiple independent supports: two lateral supports positioned at the side walls and one intermediate support positioned at the middle of the refrigerated sales space bottom plate. This segmentation allows each support to independently bear specific loads, with the intermediate support specifically preventing sagging of the middle portion while lateral supports provide overall structural stability.
2Ease of operation
If the machine unit support plate is made movable for service access, then ease of operation is improved, but reliability worsens
Solution Approach 1:
The machine unit support plate transitions from a static structure to a dynamic one, capable of moving between a slid-in position (for normal operation) and a drawn-out service position (for maintenance). The elongate opening in the intermediate support enables this dynamic movement while maintaining structural integrity during operation.
Solution Approach 2:
The elongate opening acts as an intermediary element between the intermediate support and the movable machine unit support plate. It provides guidance and constraint for the support plate's movement while allowing sufficient travel distance for service access, mediating between the need for stability and the need for mobility.
3Area of stationary object
If the machine unit support plate extends fully between side walls, then machine unit space is maximized, but the intermediate support cannot prevent sagging
Solution Approach 1:
The intermediate support introduces a new spatial dimension to the structure by extending vertically downward from the refrigerated sales space bottom plate to the floor. This vertical extension creates an additional support point at the middle of the machine unit support plate, preventing sagging without reducing the horizontal area available for the machine unit.

AI summary
A refrigerated sales furniture, comprises a furniture body having a refrigerated sales space (6) for storing goods to be presented therein and a machine unit space (8) positioned below the refrigerated sales space (6), and separated from the refrigerated sales space (6) by a refrigerated sales space bottom plate (10); the machine unit space (8) being enclosed laterally by side walls (12, 14), the undersides of which are for supporting the refrigerated sales furniture (2) against a floor; an intermediate support (16) extending downwardly from an intermediate position of the refrigerated sales space bottom plate (10) between the side walls (12, 14), for supporting the refrigerated sales space bottom plate (10) against a floor; wherein a machine unit support plate (18) is provided forming the underside of the machine unit space (8); the machine unit support plate (18) extending between a left outermost position adjacent the left side wall (12) and a right outermost position adjacent the right side wall (14); the machine unit support plate (18) being movable between a slid-in position and a drawn-out service position; the machine unit support plate (18) comprising an elongate opening (20) through which the intermediate support (16) extends, the length of the elongate opening (20) allowing a movement of the machine unit support plate (18) between the slid-in position and the drawn-out service position.
