Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple storage compartments are cooled independently with separate air supply systems, then temperature control precision is improved, but device complexity increases
Solution Approach 1:
The cooling device is divided into multiple independent storage compartments (first space, second space, third space), each with its own air supply duct and air flow control means. This segmentation allows each compartment to be cooled independently with precise temperature control, while the modular structure manages the complexity by creating repeatable units.
Solution Approach 2:
Each air supply duct is equipped with adjustable air flow control means (dampers) that can dynamically regulate the amount of cold air supplied to each space. This dynamic control capability enables precise temperature adjustment for different storage requirements without requiring a completely separate static cooling system for each compartment.
2Productivity
If air flow control means are provided on each air supply duct, then cooling efficiency is improved, but manufacturing cost increases
Solution Approach 1:
The cooling system uses multiple air supply ducts with individual air flow control means for each storage space. This segmented approach improves cooling efficiency by allowing optimized air distribution to each compartment based on its specific thermal requirements, while the repetition of standardised duct and control assemblies helps manage manufacturing costs through modular production.
Solution Approach 2:
The air flow control means on each duct allows adjustment of air flow parameters (volume, velocity) to optimize cooling efficiency for different storage conditions. This parameter adjustability enables a single duct design to serve multiple cooling scenarios, reducing the need for completely customised ductwork for each application.
3Measurement precision
If multiple fans are used to generate air flow in each inner guide, then air flow control precision is improved, but device complexity increases
Solution Approach 1:
When there are multiple inner guides in the cooling device, each inner guide is equipped with its own fan to generate and control air flow independently. This segmentation ensures that air flow precision is maintained in each section of the cooling system, while the modular fan integration into individual inner guides manages the overall system complexity.
