Wire Fitting Bracket with Rotation Restricting Protrusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering apparatuses face issues with erroneous fitting of the wire fitting bracket when connecting the connecting wire to the steering column, leading to ineffective rotation restriction and potential disconnection.
Innovation Solution
The proposed solution incorporates a wire fitting bracket with rotation restricting protrusions and an erroneous fitting prevention protrusion, which are designed to prevent incorrect orientation and ensure proper fitting by engaging with the speed reducer housing, thereby preventing erroneous fitting and ensuring secure connection.

If the wire fitting bracket is designed with additional protrusions for erroneous fitting prevention, then fitting accuracy is improved, but device complexity increases
Solution Approach 1:
The wire fitting bracket is segmented into distinct functional elements: rotation restricting protrusions that prevent rotational movement, an erroneous fitting prevention protrusion that verifies orientation, and a bolt insertion hole for fastening. Each protrusion serves a specific function and is independently positioned on the bracket body. This segmentation allows the complex functionality to be achieved through simple, discrete geometric features rather than a monolithic complex structure, thereby minimizing overall device complexity while ensuring fitting accuracy.

AI summary
A steering apparatus includes a wire fitting bracket that is fitted to an end portion of a connecting wire for connecting an outer tube to an inner tube and that has a bracket body and a plurality of protrusions. The bracket body is fitted to a steering column-side member with a bolt, and has a bolt insertion hole through which the bolt is passed. The protrusions protrude from the bracket body, and are arranged around an axis of the bolt insertion hole. The protrusions are formed of rotation restricting protrusions that restrict rotation of the wire fitting bracket and an erroneous fitting prevention protrusion that prevents erroneous fitting of the wire fitting bracket.
