Vehicle Door Handle Rotation for Intuitive Open-Close Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle door opening/closing apparatus has a non-intuitive operation for the inner door switch, which reduces operability as it differs from the conventional manual door inner handle operation.
Innovation Solution
A door opening/closing detection apparatus with a handle that rotates from a neutral position to either a pull operation position for closing or a push operation position for opening, utilizing a detection unit to recognize these positions and control the door opening/closing drive unit accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a seesaw switch is used for the inner door switch, then the door opening/closing function can be achieved, but the operability is reduced because it differs from conventional manual door inner handle operation
Solution Approach 1:
The patent copies the operational characteristics of conventional manual door inner handles by designing the automatic door handle to rotate in the same direction (toward vehicle interior for opening, toward exterior for closing), making the operation intuitive and familiar to users while achieving automated door control
Solution Approach 2:
The patent inverts the conventional seesaw switch operation by making the handle rotate toward the vehicle interior to open the door (same as manual operation) rather than using a seesaw mechanism that requires pressing in opposite directions, thereby improving ease of operation

AI summary
The present application improves operability. In the door opening/closing detection apparatus, the handle is axially supported rotatably on the base with the axis direction in vertical direction. When the handle's gripping portion is rotated from the neutral position to the push operation position rotated toward the outside of the vehicle, the first switch is activated by the handle's switch operation portion. Meanwhile, when the handle's gripping portion is rotated from the neutral position to the pull operation position rotated toward the interior of the vehicle, the handle's cam surface activates the second switch. This allows detection of operations on the handle while keeping the direction of push and pull operations on the gripping portion of the handle in line with the opening/closing direction of the door D. This allows the passenger to intuitively recognize the operation to the handle when opening and closing the door D, leading to improved operability.
