Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional truck handles are fixed and cannot be adjusted to accommodate different user physical conditions, leading to inconvenience and instability when getting on or off the vehicle, affecting safety.
Innovation Solution
A variable handle device with a grip body assembly, grip body rotation assembly, and handle movement control mechanism that allows the grip handle to be adjusted in position, enabling customization for each user, enhancing convenience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the truck handle is fixed at a predetermined position and size, then the structure is simple and easy to manufacture, but it cannot accommodate different user physical conditions, leading to inconvenience and safety issues
Solution Approach 1:
The patent applies the dynamics principle by making the handle structure movable and adjustable rather than fixed. The grip body can rotate about the door hinge axis, and the grip handle can slide along the grip body, allowing the handle to dynamically adapt to different user needs and door positions while maintaining structural simplicity through controlled degrees of freedom
Solution Approach 2:
The handle is divided into multiple independent components: a grip body that rotates with the door, a grip handle that slides along the grip body, and a coupling mechanism. This segmentation allows each component to perform its specific function independently, achieving position adaptability without requiring complete structural complexity
2Ease of operation
If the handle is fixed in size and position, then the manufacturing precision requirements are low, but the user experience and safety are compromised due to inability to customize for different physical conditions
Solution Approach 1:
The dynamic adjustment capability allows users to optimize handle position for their specific physical conditions, significantly improving ease of operation. The rotation and sliding mechanisms provide continuous adjustability, enabling each user to find the most comfortable and safe grip position
Solution Approach 2:
The handle system enables users to self-adjust the position to suit their individual needs without requiring professional installation or complex setup. The intuitive rotation and sliding actions allow users to independently customize the handle position, improving usability while keeping the manufacturing precision requirements manageable

AI summary
A variable handle device for getting on and off a vehicle includes a grip body assembly installed to a vehicle body of a vehicle, the grip body assembly configured to be rotated and protruded to an outside of the vehicle body when a door is opened and to be pushed by the door to return to an inside of the vehicle body when the door is closed, a grip body rotation mechanism configured to generate a driving force for rotating the grip body assembly to the outside of the vehicle body when the grip body assembly returns to the inside of the vehicle body, and a grip handle assembled slidably to an outside surface of the grip body assembly along the grip body assembly.
