Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bed pans are used for fluid collection, then fluid collection capability is provided, but discomfort and hygiene issues occur
Solution Approach 1:
The patent employs porous material within the fluid collection assembly to manage fluid distribution and absorption, reducing pooling and improving comfort while maintaining effective fluid collection capability
Solution Approach 2:
The fluid collection assembly utilizes a flexible, conformable structure that adapts to patient anatomy, reducing discomfort and improving hygiene compared to rigid bed pans
2Reliability
If urinary catheters are used for fluid collection, then fluid collection capability is provided, but discomfort, pain, and urinary tract infections occur
Solution Approach 1:
The device segments the fluid collection function from the urinary tract, using an external collection assembly that receives urine without requiring catheter insertion, thereby eliminating catheter-related discomfort and infection risks
Solution Approach 2:
The patent introduces an intermediary collection assembly positioned at the urethral opening that mediates between the urinary tract and collection container, avoiding direct catheter contact with the urinary system
3Reliability
If securement body with fibers is used, then movement limitation is improved, but device complexity increases
Solution Approach 1:
The securement body incorporates porous material that provides friction-based anchoring through interaction with skin texture, achieving effective movement limitation without complex mechanical structures
Solution Approach 2:
The porous securement material self-adjusts to patient anatomy and skin characteristics, automatically optimizing anchoring effectiveness without requiring complex adjustment mechanisms
