Electric Connector Coupling Structure for Human-Powered Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric connector devices for human-powered vehicles face challenges in easily connecting and disconnecting electric control cables without applying excessive force, leading to usability issues and potential size increases due to the need for additional structural elements.
Innovation Solution
The electric connector device incorporates a coupling structure with a connector base and a coupling member that attaches non-movably to an additional device, reducing force applied to the electric connection cables and utilizing the space between center axes for the coupling structure, thereby improving usability and preventing size increases.

Engineering Contradiction Analysis
1Ease of operation
If a coupling structure is added to reduce force on cables, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The coupling structure is nested within the connector base, utilizing the space between the first and second center axes. The coupling member is integrated into the connector base structure, allowing the coupling function to be embedded without adding external protrusions or separate components that would increase overall device complexity.
Solution Approach 2:
The coupling structure operates in a different spatial dimension by utilizing the area between the two center axes of the connection ports. This allows the coupling function to be achieved without increasing the device's external dimensions, effectively adding functionality in the unused internal space.

AI summary
An electric connector device for a human-powered vehicle comprises a connector base and a coupling structure. The connector base includes a first connection port and a second connection port. The first connection port defines a first center axis. The second connection port defines a second center axis. The second center axis is spaced apart from the first center axis as viewed in a predetermined direction. The coupling structure is configured to detachably attach the connector base to an additional device so that the connector base is non-movably attached to the additional device. The coupling structure is provided between the first center axis and the second center axis as viewed in the predetermined direction.
