Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional endoscopic plication sutures are used to reduce gastric volume, then the procedure is less invasive, but the sutures become undone in a short while and do not present permanent treatment
Solution Approach 1:
The closing wall is configured with an inclined surface that forms an angle between 20° and 80° with the longitudinal axis of the chamber. This curved/angled configuration allows the suction force to be applied at an optimal angle to the tissue, enhancing the approximation and pressing effect on the sutured tissues, thereby ensuring permanent merging while maintaining the less invasive endoscopic approach
Solution Approach 2:
The device utilizes suction (negative pressure) applied through the closing wall to create a pressing effect on the sutured tissues. The suction force, combined with the inclined closing wall geometry, ensures continuous and effective approximation of the tissue edges, preventing suture failure and achieving permanent treatment results
2Ease of operation
If conventional endoscopic plication sutures are used, then the procedure can be performed endoscopically, but internal lesions may occur leading to patient death
Solution Approach 1:
The device incorporates a visual inspection mechanism through the endoscope that allows real-time monitoring of the suturing process and tissue approximation. The operator can observe the tissue handling and adjust the suction force or suture placement to prevent excessive tension or damage, thereby reducing the risk of internal lesions while maintaining the endoscopic approach
Solution Approach 2:
The device allows controlled adjustment of suction parameters (pressure level) and suture tension to optimize tissue approximation without causing damage. By dynamically adjusting these parameters, the procedure achieves effective suturing while minimizing the risk of internal lesions and complications
3Volume of moving object
If conventional endoscopic plication sutures are used, then the procedure can reduce intragastric volume, but the sutures do not present sufficient approximation under pressure
Solution Approach 1:
The inclined closing wall configured at 20°-80° creates an optimized force transmission path from the suction source to the tissue. This angular geometry ensures that the suction force is effectively converted into radial pressing action on the sutured tissues, achieving sufficient approximation and strong holding effect to maintain intragastric volume reduction
Solution Approach 2:
The device employs controlled suction (negative pressure) that is transmitted through the closing wall to the sutured tissues. This pneumatic force, combined with the mechanical suture structure, provides sufficient approximation strength to maintain effective intragastric volume reduction without requiring excessive mechanical force that could cause tissue damage
