Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical coupling elements in electric machines are not securely fastened during transport, leading to potential damage and loss, and their installation and removal are not ergonomically favorable.
Innovation Solution
A mechanical connection unit with a fixing means and a rotatably arranged receiving means that allows secure fastening and easy removal of electrical coupling elements to an interconnection ring, featuring snap-lock connections and ergonomic design for assembly and transport protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrical coupling element is left unfastened during transport, then it remains accessible for connection, but it cannot be securely stored and hangs freely movable causing damage risk
Solution Approach 1:
The receiving means is designed to be rotatable between a first position (transport position) for secure storage and a second position (operating position) for accessibility. This dynamic positioning allows the electrical coupling element to be protected during transport by rotating the receiving means to the first position, and easily accessible during operation by rotating to the second position, thus resolving the contradiction between protection and accessibility
Solution Approach 2:
The receiving means is pre-configured with a transport position that provides secure storage before the electrical coupling element is needed for operation. By preparing the receiving means in advance with this dual-position capability, the system ensures protection during transport while maintaining ease of operation when needed
2Reliability
If the electrical coupling element is securely fastened during transport, then damage is prevented, but installation and removal are not ergonomically favorable
Solution Approach 1:
The rotatable receiving means provides a mechanical advantage for ergonomic operation. The rotation mechanism allows the electrical coupling element to be easily installed and removed through simple rotational motion rather than complex fastening operations, maintaining ease of operation while achieving secure fastening in the transport position
Solution Approach 2:
The receiving means acts as an intermediary between the electrical coupling element and the fixing means. It provides a user-friendly interface for installation and removal while ensuring secure fastening when in the transport position, thus resolving the contradiction between secure fastening and ergonomic operation
3Reliability
If a fixed fastening mechanism is used, then secure storage is achieved, but easy removal for connection is lost
Solution Approach 1:
The rotatable receiving means transforms a static fastening mechanism into a dynamic one. In the first position, it provides secure storage equivalent to a fixed mechanism. In the second position, it enables easy removal for connection. The rotational movement allows seamless transition between these states, resolving the contradiction between secure storage and easy removal

AI summary
A mechanical connection unit for fastening an electrical coupling element to an interconnection ring of an electric machine. The connection unit includes a fixing component, which can be interlockingly and/or frictionally positioned on the interconnection ring, and a receiving component, which is rotatably mounted on the fixing component and is provided for releasably fixing the electrical coupling element. The receiving component can be rotated from a first position to a second position for removal of the electrical coupling element.
