Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manufacturing apparatus and mold are used to produce cabinets with thermal insulation partition plates, then thermal insulation structure can be formed, but the manufacturing apparatus is complex, costly, and prone to damage
Solution Approach 1:
The cabinet is divided into a frame structure and separate thermal insulation boards. The thermal insulation boards are detached from the cabinet body during transportation and can be assembled later, eliminating the need for complex manufacturing apparatus to integrate these components during production.
Solution Approach 2:
The thermal insulation boards are pre-formed as separate components before cabinet assembly. This preliminary preparation allows the boards to be manufactured independently using simpler processes, avoiding the need for complex integrated manufacturing apparatus.
2Reliability
If thermal insulation partition plates are integrated into cabinet design, then thermal insulation function is achieved, but large manufacturing apparatus and mold are required
Solution Approach 1:
The thermal insulation system is segmented into separate thermal insulation boards that can be produced independently using simple molding processes, rather than requiring large integrated manufacturing apparatus to produce the entire cabinet with embedded insulation.
Solution Approach 2:
The thermal insulation boards act as intermediary components between the cabinet frame and the thermal insulation function. These boards can be manufactured separately and then attached to the frame, eliminating the need for complex integrated manufacturing.
3Ease of manufacture
If mold is damaged during production, then replacement is required, but replacement requires lot of manpower and financial resources
Solution Approach 1:
The manufacturing process is segmented into simple board production using durable molds, followed by separate assembly. The molds used for producing thermal insulation boards are simpler and more durable, reducing replacement costs and manpower requirements.
4Productivity
If semi-finished refrigerators are transported with all components assembled, then complete product is delivered, but lot of space is occupied causing resource waste
Solution Approach 1:
The refrigerator components are segmented into the frame structure and separate thermal insulation boards. During transportation, the insulation boards are detached and stored separately, significantly reducing the space occupied by semi-finished refrigerators and improving transportation efficiency.
Solution Approach 2:
The thermal insulation boards are designed to be thin and flat, allowing them to be stacked and stored in a compact manner during transportation. This dimensional optimization reduces the space required for transporting semi-finished refrigerators.
