Vehicle Handle Cable Connection Guide Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional handle device for vehicles faces challenges in easy engagement and assembly of the inner cable with the engagement portion, leading to reduced ease of operation and increased complexity.
Innovation Solution
A handle device with a connection aid that restricts the movement of the inner cable's connection section into a cable connection hole, forming a closed circular hole to prevent falling and reduce clanking, and includes a guide hole to stabilize the cable's posture, allowing for easier and more reliable connection and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inner cable is engaged with the engagement portion in a conventional manner, then the cable connection is secure, but the ease of engagement and assembly is reduced
Solution Approach 1:
A guide member is introduced as an intermediary component between the connection section and the cable connection hole. The guide member includes a guide hole that receives the connection section and guides it into the cable connection hole, making the engagement process easier while maintaining secure connection through the guide structure.
Solution Approach 2:
The guide member is prepared in advance with the guide hole positioned and oriented correctly before the assembly process. This preliminary positioning ensures that the connection section can be easily guided into the cable connection hole without requiring precise manual alignment during assembly.
2Ease of manufacture
If a cut-out portion is used for cable connection, then the connection process is simpler, but clanking occurs causing stroke loss
Solution Approach 1:
The guide member acts as a flexible guiding structure that allows the connection section to move smoothly into the cable connection hole. This eliminates the need for cut-out portions while preventing clanking, as the guide hole provides a continuous path for the connection section.
3Ease of operation
If the cable connection hole is open with a cut-out, then assembly is easier, but wind can enter the vehicle interior
Solution Approach 1:
The guide member serves as a covering structure that encloses the cable connection hole while still allowing the connection section to pass through the guide hole. This eliminates the need for open cut-out portions, preventing wind from entering the vehicle interior while maintaining assembly ease.

AI summary
A handle device for a vehicle is provided with: an operating section rotatably connected to a handle base; a cable device formed by inserting in a slidable manner an inner cable, which has a connection section provided at the front end thereof, into an outer cable, the cable device being configured in such a manner that the connection section of the inner cable is fitted to a cable connection hole, which is formed in the operating section, to enable operating force applied to the operating section to be transmitted to a door lock device on the vehicle side; and a connection aid connected to the front end of the outer cable and mounted on the handle base while holding the connection section of the inner cable in a movable manner.
