Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigeration devices often experience deformation of horizontal beams during transportation due to impact and lower strength, especially in wider units.
Innovation Solution
A refrigeration device design featuring a beam with a reinforcing member between the bottom wall and inner liner, encasing a cavity filled with thermal insulation material, which enhances the beam's strength and distributes impact forces to prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a beam connects the lower housing plate and inner liner in wider refrigeration devices, then the structural span is increased, but the beam is more prone to deformation due to impact and bumping during transportation
Solution Approach 1:
The beam bottom wall is constructed as a composite structure combining the original beam material with a reinforcing member (such as a steel plate or aluminum plate) affixed to its outer surface. This composite construction significantly enhances the bending resistance and impact strength of the bottom wall, preventing deformation during transportation while maintaining the required width span for wider refrigeration devices.
Solution Approach 2:
The reinforcing member is pre-affixed to the beam bottom wall before the beam is installed in the refrigeration device. This preliminary reinforcement ensures that the beam is already strengthened against impact and bumping forces before it encounters transportation stresses, preventing deformation proactively rather than reactively.
2Strength
If a reinforcing member is affixed on the beam to enhance strength, then the beam resistance to deformation is improved, but the device complexity increases
Solution Approach 1:
The reinforcement solution is segmented into discrete reinforcing members (such as individual plates or strips) that are affixed to specific high-stress areas of the beam bottom wall, rather than reinforcing the entire beam structure uniformly. This targeted segmentation enhances strength where needed while minimizing the overall complexity and material usage.
Solution Approach 2:
The reinforcing members are strategically positioned at the bottom wall of the beam where impact and bumping forces are most concentrated during transportation. This local reinforcement approach provides maximum strength enhancement at the critical deformation zone without unnecessarily complicating the entire beam structure or adding weight to non-critical areas.

AI summary
A refrigeration device has a housing with an inner liner, a lower housing plate, and a beam connecting the inner liner and the lower housing plate. A reinforcing member is fixed on the beam for enhancing a strength of a bottom wall. A cavity is formed between the reinforcing member and a front wall. Thermal insulation material formed by foaming is disposed inside and outside the cavity. The reinforcing member and the front wall of the beam enclose the cavity, so that the thermal insulation material enables the beam and the reinforcing member to form a whole for bearing a force. The assembly is thus improved for preventing deformation of the bottom wall due to impact.
