Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fresh-keeping bags are made into strips and rolled into tubes, then storage efficiency is improved, but ease of use deteriorates as bags must be torn out individually
Solution Approach 1:
The continuous strip of fresh-keeping bags is segmented into individual bags through automatic cutting. The cutting assembly includes a cutting blade that divides the continuous strip into separate usable bags, resolving the contradiction by providing both efficient strip storage and individual bag usability without manual tearing
Solution Approach 2:
The machine performs automatic cutting and folding of the fresh-keeping bags without requiring manual intervention. The cutting assembly automatically separates bags from the strip, and the folding mechanism automatically folds them into the storage box, eliminating the need for users to manually tear out individual bags
2Volume of moving object
If bags are transported in rolled tubes, then compactness is improved, but transport smoothness deteriorates causing inefficiency
Solution Approach 1:
The transport mechanism uses dynamic elements including a transport wheel with suction cups that actively engage with the bag strip. The suction cups create variable adhesion forces to maintain contact during transport, allowing smooth movement through the rolling mechanism without compromising compactness
Solution Approach 2:
The transport wheel incorporates suction cups that use vacuum pressure to hold and transport the plastic bag strip. This pneumatic mechanism ensures smooth transport through the rolling process while maintaining compact packaging, resolving the contradiction between compactness and transport smoothness
3Adaptability or versatility
If multiple independent mechanisms are used for folding, then folding capability is improved, but power consumption increases
Solution Approach 1:
The folding mechanism combines multiple folding functions into a single integrated assembly. The first and second folding assemblies work together with shared components to perform multiple folding operations simultaneously, reducing the number of independent mechanisms and lowering power consumption while maintaining comprehensive folding capability
Solution Approach 2:
The folding mechanism is designed as a multi-functional unit that can perform various folding operations on different types of fresh-keeping bags. The universal design allows a single mechanism to handle multiple folding tasks that would otherwise require separate dedicated mechanisms, reducing overall power consumption
4Device complexity
If folding devices lack storage boxes, then device simplicity is improved, but storage effectiveness deteriorates
Solution Approach 1:
The storage box is integrated into the folding device structure, with the folding mechanism positioned above the storage box. The folded bags are automatically deposited into the storage box, creating a nested arrangement where the storage function is embedded within the folding device without significantly increasing overall complexity
Solution Approach 2:
The storage box is pre-positioned and ready to receive folded bags before the folding operation completes. The cutting assembly and folding mechanism are arranged to automatically deposit finished bags into the storage box, eliminating the need for separate manual storage actions and improving storage effectiveness
