Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple molds are arranged in a single metal mold structure with shared Peltier elements, then device complexity is reduced, but temperature uniformity deteriorates due to thermal conductivity variations across different filling holes
Solution Approach 1:
The patent divides the metal mold structure into multiple independent mold units, each with its own Peltier element for temperature control. This segmentation allows each mold to be controlled independently, preventing temperature interference between adjacent molds while maintaining uniform temperature distribution within each mold's filling holes.
Solution Approach 2:
The patent introduces thermally insulating members positioned between adjacent metal molds to prevent heat transfer between them. These insulating members act as intermediaries that block thermal interference, allowing each mold to maintain its designated temperature without being affected by neighboring molds.
2Adaptability or versatility
If Peltier elements are used for temperature control, then temperature adjustment capability is improved, but temperature interference between adjacent molds occurs due to thermal conductivity
Solution Approach 1:
The patent introduces thermally insulating members positioned between adjacent metal molds to prevent heat transfer between them. These insulating members act as intermediaries that block thermal interference, allowing each mold to maintain its designated temperature without being affected by neighboring molds.
Solution Approach 2:
The patent applies different thermal properties to different regions of the system: high thermal conductivity within each mold for uniform temperature distribution, and low thermal conductivity between molds for isolation. This local differentiation of thermal properties enables both temperature control capability and prevention of temperature interference.
3Productivity
If molds are cooled during mass production, then productivity is improved, but temperature control difficulty increases due to larger heat dissipation requirements
Solution Approach 1:
The patent divides the temperature control system into multiple independent units, each with its own Peltier element. This allows each mold to be cooled independently according to its specific heat dissipation requirements, making temperature control during mass production more manageable and efficient.
Solution Approach 2:
The patent provides dedicated cooling capacity for each mold through individual Peltier elements, ensuring that each mold receives sufficient cooling power even during mass production. This partial allocation of cooling resources to each unit prevents temperature control difficulty from arising.
