Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of refrigerating sales furniture is time-consuming and expensive due to the large number of components involved.
Innovation Solution
The design includes a simplified structure with fewer components, utilizing injection-molded side members that incorporate a metal frame for stability and a bar structure for rigidity, along with features like cable channels and injection gates for easy assembly and insulation, reducing the complexity and cost of production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional multi-component structure is used, then structural stability is achieved, but assembly time and cost increase
Solution Approach 1:
The patent combines multiple separate components (side wall, metal frame, insulation layer, bar structure) into a single injection-molded side member. This merging of components directly reduces assembly time and the total number of parts while maintaining the structural stability that would otherwise require multiple separate elements to provide collectively.
Solution Approach 2:
The side member uses composite construction with a polyurethane matrix containing embedded metal frame elements and bar structures. This composite approach allows a single component to achieve the structural stability of multiple separate components while simplifying the overall assembly process and reducing the number of parts needed.
2Ease of manufacture
If traditional assembly process is used, then component stability is ensured, but production cost increases
Solution Approach 1:
The metal frame and bar structures are pre-integrated into the side member during the injection molding process itself. This preliminary action of embedding structural elements before final assembly eliminates the need for separate attachment operations, reducing both assembly time and production costs while ensuring structural stability is built-in from the start.
3Device complexity
If simplified structure with fewer components is used, then assembly process is simplified, but structural stability may be compromised
Solution Approach 1:
The single side member component achieves structural stability through composite construction, embedding a metal frame and bar structures within the polyurethane matrix. This allows the simplified single-component design to maintain the structural integrity that would otherwise require multiple separate components working together.
Solution Approach 2:
The side member features localized reinforcement with metal frame elements and bar structures positioned at specific locations within the polyurethane matrix. This local quality approach ensures structural stability is provided exactly where needed within the simplified single-component design, maintaining strength without requiring additional overall complexity.
