Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the joint section is made with sufficient mechanical strength to withstand repeated attachment and detachment from the hanger, then the durability against attachment/detachment is improved, but the device complexity increases
Solution Approach 1:
The joint section is divided into multiple partition structural members (first, second, third partition structural members) that are coupled together. This segmentation allows each member to bear specific loads during attachment/detachment operations, distributing the mechanical stress and enhancing durability without requiring a monolithic complex structure.
Solution Approach 2:
The partition structural members are arranged in different spatial dimensions (longitudinal direction along the treatment tool channel, lateral direction perpendicular to it). This multi-dimensional arrangement provides mechanical strength in multiple directions simultaneously, addressing the complexity of withstanding various forces during hanger attachment and detachment.
2Strength
If the joint section is designed to withstand mechanical loads during rotation and sway operations, then the mechanical strength during operation is improved, but the ease of operation deteriorates
Solution Approach 1:
The joint section is segmented into multiple partition structural members that can move relative to each other, allowing rotation and sway operations while maintaining overall structural strength. Each partition member can accommodate operational movements independently.
Solution Approach 2:
The joint section incorporates dynamic characteristics by allowing the partition structural members to move and adjust during rotation and sway operations. This dynamic design maintains mechanical strength while facilitating ease of operation.
3Reliability
If the frame with partition structural members is added to enhance mechanical strength, then the durability during various endoscopic operations is improved, but the device complexity increases
Solution Approach 1:
The frame is divided into multiple partition structural members that are coupled together, creating a modular structure. This segmentation provides enhanced durability during endoscopic operations while keeping the structural complexity manageable through standardized coupling mechanisms.
Solution Approach 2:
The frame structure combines multiple partition structural members into a composite framework that provides enhanced mechanical strength and durability. This composite structure distributes loads effectively during various endoscopic operations.
