Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If biocompatible adhesives are used to improve adhesion to organs, then adhesion strength is improved, but inflammation and tissue damage occur due to adhesive penetration
Solution Approach 1:
The patent removes adhesives entirely from the system by using a self-adhering structure with incision portions that physically interlock with organ tissue through mechanical engagement, eliminating the harmful adhesive substance while maintaining strong adhesion
Solution Approach 2:
The device structure itself provides the adhesion function through its geometric design with incision portions that automatically engage with tissue contours without requiring external adhesive materials
2Reliability
If implantable-type devices are used to avoid detachment, then adhesion stability is improved, but tissue damage and inflammation occur due to Young's modulus mismatch
Solution Approach 1:
The patent employs a flexible support structure with incision portions that can conform to organ surfaces, providing stable adhesion through mechanical interlocking while the flexibility prevents stress concentration and tissue damage
Solution Approach 2:
The device incorporates flexible supports that can dynamically adapt to organ movement and deformation, maintaining reliable adhesion stability while accommodating physiological changes without causing tissue damage
3Area of stationary object
If planar-type devices are used to cover entire organ surfaces, then treatment coverage is improved, but detachment occurs under physical activity or impact
Solution Approach 1:
The patent divides the planar support into multiple flexible support segments with incision portions, allowing each segment to independently conform to surface contours and maintain adhesion stability under physical stress while covering the entire organ surface
4Device complexity
If planar-type devices are applied to curved surfaces, then device simplicity is maintained, but adhesion completeness is reduced leading to decreased therapeutic effectiveness
Solution Approach 1:
The patent introduces curvature through incision portions in the flexible support, enabling the device to conform to curved organ surfaces and achieve complete adhesion while maintaining relatively simple structural composition
