Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a consumable portion is directly provided in a durable portion, then device simplicity is improved, but device versatility and ease of repair worsen
Solution Approach 1:
The device is divided into three distinct portions: durable portion, semi-durable portion, and consumable portion. The semi-durable portion acts as an intermediate layer that can be replaced independently, allowing the durable portion to remain intact while enabling versatility through interchangeable consumable portions.
Solution Approach 2:
The semi-durable portion serves as an intermediary component between the durable portion and consumable portion. This mediator allows for easy replacement of consumable portions without affecting the durable portion, thereby improving both versatility and ease of repair while maintaining reasonable device simplicity.
2Adaptability or versatility
If a semi-durable portion is added to receive consumable portions, then device versatility and ease of repair are improved, but device complexity worsens
Solution Approach 1:
The device structure is segmented into three replaceable portions with clearly defined functions. The semi-durable portion is designed as a standardized interface that simplifies the replacement process, making the added complexity manageable through modular design.
Solution Approach 2:
The semi-durable portion is designed with universal compatibility to receive different types of consumable portions. This multi-functional interface allows a single semi-durable portion to work with multiple consumable variants, reducing overall system complexity while maintaining high versatility.
3Device complexity
If conventional electrospinning devices are used without grounding mechanisms, then device simplicity is improved, but user safety worsens
Solution Approach 1:
The device incorporates self-grounding mechanisms where the durable portion and semi-durable portion are designed with integrated grounding paths. The system automatically establishes safe grounding connections during normal operation, eliminating the need for additional complex safety devices while ensuring user safety.
