Adjustable Vehicle Assist Grip for Height Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assist grips for vehicles are difficult to use for passengers of varying heights and sizes, particularly short children and tall adults, as they are not adjustable and can be slippery when grip strength is weak, making it hard to get in and out of the vehicle.
Innovation Solution
An adjustable assist grip with a grip head portion that can be attached at different heights along the vehicle door opening, featuring a supporting member with a horizontal and upwardly-extending portion, allowing easy force application and adaptable to individual physical sizes, and a design that facilitates easy grasping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the assist grip has a fixed installation height, then the structure is simple, but it is hard to use for passengers of different heights (short children and tall adults)
Solution Approach 1:
The assist grip transitions from a fixed installation height to an adjustable height system. The supporting member can be positioned at multiple heights along the grip main body through the height adjustment unit, allowing the grip to adapt dynamically to different passenger sizes while maintaining structural simplicity through standardized adjustment mechanisms.
Solution Approach 2:
The assist grip is divided into modular components: the grip main body, the supporting member, and the height adjustment unit. This segmentation allows independent adjustment of the supporting member's position along the grip main body, enabling adaptability to different heights without complicating the overall structure.
2Ease of operation
If the assist grip has a smooth surface, then it is easy to manufacture, but it becomes slippery when grip strength is weak
Solution Approach 1:
The grip head portion features a locally modified surface with increased roughness compared to the smooth grip main body. This local quality change provides enhanced friction and grip ability where needed (at the contact point) while maintaining the simplicity of smooth surface manufacturing for the majority of the structure.
3Ease of operation
If the grip head portion is positioned close to the grip main body, then the structure is compact, but it is difficult to grasp
Solution Approach 1:
The supporting member extends horizontally from the grip main body, creating a spatial separation between the grip head portion and the main vertical structure. This dimensional arrangement allows the grip head to be positioned at an optimal grasping distance while maintaining a compact overall volume through efficient spatial utilization.

AI summary
An assist grip for a vehicle to which a force can be easily applied from above when a passenger gets in and out of the vehicle, facilitating the movement of the passenger at that time. The assist grip includes a grip main body 4 vertically provided along a door opening of a vehicle2. The grip main body 4 includes the grip head portion 6. The passenger can vertically apply a force to the grip head portion 6 when getting in and out of the vehicle, and thus he/she is allowed to easily get in and out of the vehicle. Moreover, a supporting member 5 is provided in the grip head portion 6 and an attachment position of the grip head is adjustable in relation to the grip main body 4, enabling the attachment position to be adjusted according to a passenger's physical size, further improving its convenience.
