Adjustable Vehicle Assist Handle for Small-Stature Occupants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assist handles are not suitable for individuals with small sitting heights or children, as they require a predetermined sitting height to be used effectively, leading to potential balance issues and risk of falling during driving.
Innovation Solution
A height adjustable assist handle is designed with a partitioned adjustment part and support parts, allowing extension members to be pulled out from guide holes for height adjustment, enabling users with small sitting heights to conveniently use the handle by gripping and pulling down the adjustment part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the assist handle is mounted at a fixed position on the head liner, then the structure is simple and stable, but users with small sitting heights cannot reach or use it effectively
Solution Approach 1:
The assist handle is divided into multiple segments: a fixed support part mounted on the head liner and a movable adjustment part that can be pulled down. The extension member connects these parts, allowing the adjustment part to move independently downward while the support part remains fixed, enabling users with small sitting heights to reach and use the handle effectively.
Solution Approach 2:
The assist handle transitions from a static fixed position to a dynamic adjustable position. The extension member allows the adjustment part to move downward when pulled by the user, providing height adaptability. After use, the return spring restores the adjustment part to its original position, enabling dynamic adaptation to different user needs.
2Adaptability or versatility
If the assist handle is made height-adjustable with extension members, then usability for various sitting heights is improved, but the device complexity increases
Solution Approach 1:
The assist handle is divided into multiple segments: a fixed support part mounted on the head liner and a movable adjustment part that can be pulled down. The extension member connects these parts, allowing the adjustment part to move independently downward while the support part remains fixed, enabling users with small sitting heights to reach and use the handle effectively.
Solution Approach 2:
The system uses a return spring that automatically restores the adjustment part to its original position after use, eliminating the need for manual resetting or complex control mechanisms. The extension member's flexible connection allows automatic engagement and disengagement during adjustment, reducing the need for additional locking or securing devices.

AI summary
By separating a middle portion of a handle body to be divided into an adjustment part and support parts formed at both sides of the adjustment part and allowing the adjustment part to be connected to the support parts with extension members, it allows the extension members to get out of the support parts when only the adjustment part is gripped and pulled down to allow the adjustment part to move down so that an occupant with a small sitting height can also conveniently use the assist handle. In particular, by allowing the extension members to be integrally formed with the adjustment part at both ends of the adjustment part, when the adjustment part is formed, it is possible to easily manufacture the assist handle without undergoing a separate manufacturing process so that an occupant can conveniently use the assist handle by conveniently adjusting a height of the assist handle.
