Solution Overview
Problem
Existing detachable connections for cable ducts and similar sections face challenges such as requiring tools for assembly, difficulty in reaching awkward spaces, limited detachability due to material tolerances and elasticity, and inability to connect with rigid materials, leading to insecure or overly tight connections.
Innovation Solution
A system featuring first and second insertion ribs forming grooves, with resilient material between sections, allowing for tool-free assembly and detachment without deformation, ensuring secure yet loose connections suitable for various materials and environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap connections are used to enable tool-free assembly, then ease of operation is improved, but connection reliability deteriorates due to tolerances and material elasticity
Solution Approach 1:
A resilient intermediate element is introduced between the first section and connecting parts to mediate the connection. This resilient element absorbs dimensional tolerances and material elasticities, enabling reliable detachable connections without requiring precise manufacturing tolerances or special tools for assembly.
2Reliability
If resilient material is added to accommodate tolerances, then connection reliability is improved, but device complexity increases
Solution Approach 1:
A resilient element in the form of a flexible strip or film is used to accommodate dimensional variations and material elasticities. This simple flexible component effectively absorbs tolerances without requiring complex adjustment mechanisms or multiple parts, thus improving connection reliability while adding minimal structural complexity.
3Strength
If rigid materials are used for durability, then strength is improved, but adaptability deteriorates due to inability to deform for connection
Solution Approach 1:
The connection system is segmented into three independent components: rigid first section, rigid connecting parts, and a separate resilient intermediate element. This segmentation allows the main structural components to be made from durable rigid materials while the dedicated resilient element provides the necessary flexibility and adaptability for connection, thus resolving the conflict between strength and adaptability.
4Reliability
If sealing elements are added to ensure tight connection, then connection reliability is improved, but ease of operation deteriorates due to difficulty in detachment
Solution Approach 1:
The resilient element provides a dynamic connection that automatically adjusts to dimensional variations and material elasticities during both assembly and detachment. This dynamic characteristic enables the connection to maintain reliable sealing under normal conditions while remaining easily detachable when force is applied, as the resilient element can deform to facilitate removal.
