Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional material input method is used, then the input speed may be sufficient, but material scattering occurs causing work area contamination
Solution Approach 1:
The patent introduces an intermediary device (the specialized input apparatus with sealed flow path) between the material source and the work area. This intermediary contains the material during transfer, preventing scattering while maintaining efficient input through the structured flow path design.
Solution Approach 2:
The patent employs a sealed flow path structure that acts as a flexible containment shell. This sealed pathway guides the material from the input part through the main body to the output part without exposure to the external environment, thus preventing contamination while allowing rapid material flow.
2Productivity
If material is input rapidly, then productivity increases, but material scattering and contamination worsen
Solution Approach 1:
The sealed flow path structure contains the material during high-speed transfer, preventing scattering even when input speed is increased. The sealed pathway ensures material remains confined throughout the transfer process.
Solution Approach 2:
The input apparatus is segmented into distinct functional parts (input part, main body, output part) with a sealed flow path connecting them. This segmentation allows controlled material flow through each section, maintaining containment during rapid transfer.
3Object-affected harmful factors
If a sealed flow path system is implemented, then contamination is prevented, but device complexity increases
Solution Approach 1:
The apparatus is divided into three main segments (input part, main body, output part) connected by a sealed flow path. This segmentation provides a systematic approach to containment without requiring overly complex internal structures within each segment.
Solution Approach 2:
The sealed flow path structure serves multiple functions simultaneously: it contains the material, guides its flow, and prevents contamination. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.
