Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bendable body is passed through the control element and base body, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The bendable body is passed through the inner channel of the control element and the inner channel of the base body, with the transmission guiding body also routed through these channels. This nesting arrangement allows multiple components to occupy the same spatial pathway, enabling compact construction while maintaining operational ease through straightforward assembly and disassembly of the bentable body.
Solution Approach 2:
The inner channels in the control element and base body serve as intermediaries that guide and protect the bendable body and transmission guiding body during insertion and operation. These channels mediate between the external environment and the internal mechanisms, facilitating easy handling while organizing the complex internal structure.
2Manufacturing precision
If the transmission guiding body is made elongate and passed through channels, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The transmission system is segmented into distinct components: the elongate transmission guiding body, the control element with inner channel, and the base body with inner channel. This segmentation allows each component to be manufactured and assembled separately, improving manufacturing precision through specialized production while the modular nature helps manage the overall device complexity.
Solution Approach 2:
The transmission guiding body is nested within the inner channels of the control element and base body, creating a hierarchical structure where components are contained within one another. This nesting arrangement ensures precise alignment and transmission of deflection movements while consolidating multiple functions into a compact configuration.
3Ease of operation
If the control element and base body have concentric inner channels, then ease of operation is improved, but stability is worsened
Solution Approach 1:
The inner channels are designed with specific local qualities: the control element's inner channel has a funnel-shaped insertion opening to facilitate easy insertion of the bendable body, while the channels are positioned concentrically to maintain structural balance. This localized optimization of channel geometry and positioning improves ease of operation while preserving overall device stability through careful structural design.
