Vehicle Door Handle Inclination for Natural Hand Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle door handles disposed above the belt molding often require users to adopt unnatural postures, particularly when operating with the 'normal hand', leading to poor operability.
Innovation Solution
A vehicle door handle structure with the door handle inclined toward the front of the vehicle, allowing the pocket entrance to face diagonally rearward and diagonally upward, enabling easier operation with the 'normal hand' without raising the elbow high.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the door handle is disposed above the belt molding with the pocket entrance facing diagonally rearward and diagonally downward, then the design flexibility of the door main body is improved, but the operability for the user deteriorates
Solution Approach 1:
The patent changes the inclination angle parameter of the door handle. Specifically, the door handle is inclined toward the front of the vehicle such that the pocket entrance faces diagonally rearward and diagonally upward, with the inclination angle being 10 degrees or more and 45 degrees or less. This parameter change resolves the contradiction by making the door handle operable with normal hand posture while maintaining the design flexibility of placing it above the belt molding.
2Shape
If the pocket entrance faces diagonally rearward and diagonally downward, then the door handle can be positioned above the belt molding, but the user must raise the elbow high leading to unnatural posture
Solution Approach 1:
The patent modifies the orientation parameter of the pocket entrance by changing the inclination direction. Instead of facing diagonally rearward and diagonally downward, the pocket entrance now faces diagonally rearward and diagonally upward. This parameter change allows users to operate the door handle with natural hand posture without raising the elbow high, while maintaining the advantageous position above the belt molding.

AI summary
The vehicle door handle structure includes a door handle disposed above a belt molding on a side door of a vehicle and pulled by a user when the user opens the side door from an outside of the vehicle, and a pocket space disposed behind the door handle to receive fingers of the user, and the door handle is inclined toward the front of the vehicle with respect to the ground contact surface of the vehicle such that an entrance of the pocket space faces diagonally rearward and diagonally upward of the vehicle.
