Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual application methods are used for wound care dressings, then the application process is simple, but leakage occurs due to improper attachment and skin irregularities
Solution Approach 1:
A roller device with protrusions is introduced as an intermediary tool between the applicator and the barrier product. The roller applies uniform pressure and mechanical deformation to the barrier compound, ensuring proper adhesion to irregular skin surfaces without requiring complex manual manipulation techniques.
Solution Approach 2:
The roller device changes the physical state of the barrier compound by applying pressure and heat through rolling action. This transforms the compound from a soft, moldable state to a more firmly adhered state, improving attachment reliability while maintaining simple operation.
2Reliability
If sharp implements or heat sources are used to enhance adhesion, then attachment strength improves, but safety risks increase
Solution Approach 1:
The invention replaces dangerous mechanical methods (sharp implements) and thermal methods (heat sources) with a safer mechanical rolling system. The roller with protrusions provides controlled pressure and deformation without the risks associated with sharp tools or open flames.
Solution Approach 2:
The roller device converts the potential harm of excessive manual pressure into a beneficial controlled rolling action. The protrusions on the roller distribute pressure uniformly and create beneficial mechanical deformation that enhances adhesion without causing skin trauma or other harm.
3Area of stationary object
If barrier products are applied to irregular skin surfaces, then coverage is achieved, but adhesion becomes uneven leading to leakage
Solution Approach 1:
The roller device applies different local actions to different areas of the barrier product. The protrusions create localized pressure points and deformation zones that adapt to skin irregularities, ensuring uniform adhesion across the entire coverage area despite surface variations.
Solution Approach 2:
The roller's curved surface and protrusions allow it to conform to irregular skin topography. The spherical/curved geometry enables the roller to maintain consistent contact and pressure distribution across uneven surfaces, achieving uniform adhesion while covering the entire required area.
