Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a user manually cuts the protection plate using scissors, then the user can attempt to form a through hole, but it is difficult to form a through hole with a certain size and precision is poor
Solution Approach 1:
The patent replaces the manual scissoring operation with a punching device that uses a punch and die mechanism. The user simply positions the protection plate and activates the punching mechanism, which automatically creates a precisely sized through hole. This substitutes complex manual cutting mechanics with a specialized punching mechanism that ensures consistent, accurate hole formation without requiring manual dexterity or skill.
Solution Approach 2:
The patent employs interchangeable punches with different diameters to accommodate various stoma sizes. By changing the punch parameter (diameter) rather than changing the cutting method, the system can precisely adapt to different patient requirements. This parameter-based approach allows for precise hole size control while maintaining ease of operation through a standardized punching process.
2Adaptability or versatility
If a user manually marks and cuts the protection plate, then the user can attempt to customize the hole position, but the operation is inconvenient for users with no skills or hand motion limitations
Solution Approach 1:
The patent replaces manual marking and cutting operations with a positioning and punching system. The device includes positioning features that guide the punch to the correct location on the protection plate, eliminating the need for manual marking and freehand cutting. Users with limited hand mobility can easily position the plate and activate the punching mechanism without requiring fine motor skills or complex hand motions.
Solution Approach 2:
The punching device incorporates self-positioning features and guides that automatically align the punch with the desired hole location. The system performs its own positioning function rather than relying on manual marking and measurement by the user. This self-service capability ensures accurate hole placement while simplifying the user's task to merely positioning the protection plate and activating the mechanism.
3Object-affected harmful factors
If the protection plate is frequently replaced due to leakage and skin irritation, then skin health can be maintained, but the loss of time for replacement increases
Solution Approach 1:
The patent employs a spring-loaded punching mechanism where the spring stores mechanical energy and releases it to drive the punch through the protection plate. This elastic energy storage and release mechanism enables rapid, forceful hole creation without requiring sustained manual pressure or complex actuation systems, thereby reducing the time needed for each replacement while maintaining proper hole formation to prevent leakage and skin irritation.
