Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigeration appliances face challenges in efficiently assembling and disassembling compressors due to complex fastening mechanisms, which are difficult to access and require multiple steps, leading to increased manufacturing costs and reduced ease of repair.
Innovation Solution
A refrigeration appliance design featuring a single securing means that connects with both first and second fastening devices, utilizing a tab with specific cutouts and contours for a form-fitting connection, simplifying assembly and disassembly by reducing the number of parts and allowing for easier access during maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate securing means are used for each fastening device, then the compressor can be firmly fastened to the compressor carrier, but the assembly and disassembly process becomes complex and time-consuming
Solution Approach 1:
The patent combines multiple separate securing means into a single integrated securing means that can simultaneously engage with multiple fastening devices (first and second fastening projections). This single securing means features a body with multiple securing elements that can fasten the compressor to the carrier in one operation, eliminating the need to individually secure each fastening device separately, thus reducing assembly and disassembly time while maintaining firm fastening.
Solution Approach 2:
The single securing means is designed with multi-functionality to perform multiple fastening operations simultaneously. It can engage with different types of fastening devices (first and second fastening projections) through its multiple securing elements, making it a universal fastening solution that replaces several specialized securing means, thereby simplifying the overall assembly process.
2Reliability
If multiple separate securing means are used for each fastening device, then each fastening point can be independently secured, but the number of parts increases leading to higher manufacturing costs
Solution Approach 1:
The patent merges multiple separate securing means into one integrated component that provides equivalent or superior fastening security. This consolidation reduces the total number of parts that need to be manufactured, stored, and assembled, thereby lowering manufacturing costs while maintaining the reliability of the fastening system through its multi-element design that engages with multiple fastening projections.
3Reliability
If rear fastening devices are used for compressor mounting, then the compressor can be securely attached, but technicians cannot access them for maintenance without disassembling the entire unit
Solution Approach 1:
The patent introduces a dimension of accessibility by designing the single securing means with a configuration that allows front-side access to control rear fastening. The securing means extends from the front of the compressor, allowing technicians to manipulate and disengage the securing elements from the front, thereby gaining access to rear fastening devices without disassembling the entire compressor unit.
4Reliability
If complex fastening mechanisms are used, then the compressor can be firmly secured, but the assembly process becomes difficult and requires multiple steps
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated securing means that appears simple in structure but performs complex fastening operations. By consolidating multiple securing elements into one component, the patent reduces the number of assembly steps required while maintaining firm securing through the coordinated action of its multiple elements engaging with different fastening projections.
