Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional containers with multi-layer inliner bags are used to protect the formulation, then the material is protected from diffusion of atmospheric oxygen, water and contaminants, but the formulation still has limited shelf life and quality deteriorates during storage and transport
Solution Approach 1:
The patent introduces an absorption material as an intermediary substance between the formulation and the external environment. This material actively absorbs harmful substances (oxygen, water, carbon dioxide) that penetrate through the container walls, providing an additional protective mechanism beyond passive barrier films.
Solution Approach 2:
The container system combines multiple protective elements: the physical barrier of multi-layer inliner bags with the chemical absorption capability of getter materials. This composite approach creates a multi-layered defense system that addresses both diffusion protection and active contaminant removal.
2Device complexity
If the formulation is stored in conventional containers without absorption material, then the container structure remains simple, but the quality of manufactured electronic devices becomes inconsistent after storage
Solution Approach 1:
The absorption material is pre-installed in the container before the formulation is filled or simultaneously during the filling process. This preliminary preparation ensures that the protective mechanism is in place before contamination can occur, maintaining formulation quality without requiring complex post-processing.
Solution Approach 2:
The absorption material provides self-active protection by automatically absorbing contaminants that penetrate the container. This passive yet effective mechanism requires no external power source or control system, maintaining simplicity while ensuring consistent formulation quality.
3Reliability
If absorption material is added to the container to protect the formulation, then shelf life and quality consistency are improved, but the container structure and filling process become more complex
Solution Approach 1:
The absorption material serves multiple functions simultaneously: it absorbs oxygen, water, and carbon dioxide; maintains formulation quality; extends shelf life; and provides protection during both storage and transport. This multi-functionality justifies the additional complexity by addressing multiple protection needs with a single component.
