Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireway systems require tools for secure connection and may not maintain the connection effectively over time, leading to potential disconnection of abutting wireway sections.
Innovation Solution
A wireway connector with a snap-fit component that automatically locks into a corresponding snap-fit component on the wireway section, providing a quick and secure connection without the need for additional tools, using a combination of threaded fasteners and snap-fit connections to ensure stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wireway connectors are used with screws and slots, then the connection can be secured, but tools are required and the connection process is time-consuming
Solution Approach 1:
The wireway connector is designed with a self-aligning mechanism where the connector body automatically guides the wireway section into proper alignment during insertion. The tapered leading edge and guide surfaces enable the connector to self-position without requiring alignment tools or manual adjustment, making the connection process self-service and tool-free
Solution Approach 2:
The connector incorporates pre-formed engagement features including recesses and protrusions that are预先 shaped to automatically engage with corresponding features on the wireway section during insertion. The deformation elements are pre-configured to deform and lock into place automatically, eliminating the need for post-installation tool operations
2Reliability
If conventional wireway connectors are used with screws, then the connection can be made secure, but the connection may not maintain effectiveness over time
Solution Approach 1:
The connector employs deformation elements that undergo controlled elastic deformation during insertion and then maintain a constant locking force. The spring-like deformation elements continuously exert pressure against the wireway section, automatically compensating for any settling or thermal expansion/contraction that may occur over time, thereby maintaining connection effectiveness throughout the service life
Solution Approach 2:
The connector design includes built-in compliance features such as flexible deformation elements and cushioning recesses that absorb shocks and vibrations before they can compromise the connection. These elements provide beforehand cushioning against mechanical stresses, preventing connection failure from transient loads or vibrations during operation
3Ease of operation
If wireway sections are connected using traditional methods, then the connection can be made, but the risk of disconnection over time exists
Solution Approach 1:
The connector features a nested structure where the connector body is inserted into the wireway section, and deformation elements are nested within recesses. The connector body contains guide surfaces that lead the wireway section into proper positioning, while internal deformation elements are nested within the connector body walls. This nested arrangement ensures that all components work together to prevent disconnection while maintaining installation simplicity
Solution Approach 2:
The deformation elements serve as intermediary components between the connector body and the wireway section. These elements deform during insertion to create a mechanical interlock, then maintain a continuous locking force that prevents disconnection. The intermediary deformation elements transfer and distribute loads, ensuring reliable connection without requiring complex multi-step installation procedures
