Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic protection device is used to protect the guide wire tip, then the tip is protected from damage, but the device becomes costly and time-consuming to produce
Solution Approach 1:
The patent applies this principle by replacing expensive plastic protectors with a disposable paper-based protection device. The paper material is significantly cheaper to produce, eliminating the need for complex mold designing and manufacturing while maintaining the protective function for the guide wire tip during the procedure.
Solution Approach 2:
The patent changes the material parameter from plastic to paper, which fundamentally alters the manufacturing approach. Paper materials can be produced through simple cutting and folding processes without requiring injection molding or complex fabrication methods, thereby reducing production costs and time.
2Reliability
If a solid plastic protector structure is used, then the tip is protected, but the device is not environmentally friendly and causes pollution
Solution Approach 1:
The patent employs disposable paper materials that are biodegradable and environmentally friendly, replacing persistent plastic waste. The paper protectors can be safely disposed of after use without causing long-term environmental harm, aligning with eco-friendly medical device practices.
3Reliability
If a solid plastic protector is designed for a specific guide wire specification, then the tip is protected, but a new protector must be designed and manufactured for each different specification
Solution Approach 1:
The patent creates a universal paper-based protector design that can accommodate multiple guide wire specifications through its foldable, adjustable structure. The protective device adapts to different guide wire diameters and configurations without requiring separate designs, achieving multi-functionality across various medical applications.
Solution Approach 2:
The patent introduces dynamic adjustability through foldable paper structures that can be configured to fit different guide wire specifications. The protective device transitions from a static solid plastic form to a dynamic paper structure that can be folded and shaped to match various guide wire dimensions, enhancing versatility.
4Ease of operation
If the guide wire is taken out by removing the plastic protector first, then the guide wire can be removed, but the tip is prone to damage during removal
Solution Approach 1:
The patent segments the protective device into a paper-based structure that can be easily folded and removed without putting stress on the guide wire tip. The foldable paper protector allows the tip to be accessed and removed gently, avoiding the damage risk associated with solid plastic protectors that require forceful removal.
5Ease of manufacture
If additional mold designing and mold making is performed for plastic protectors, then the protective device can be manufactured, but the process becomes costly and time-consuming
Solution Approach 1:
The patent eliminates the need for expensive mold designing and manufacturing by using disposable paper materials. The simple paper-based structure can be produced through basic cutting and folding processes, completely avoiding the time-consuming mold fabrication required for plastic injection molding.
