Vehicle Sliding Door Handle Assembly for Manual-Electric Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuating assemblies for displaceable door elements in vehicles struggle to provide both manual and electrical actuation, especially when electrically actuated door elements require manual operation, and there is a need for a cost-effective solution.
Innovation Solution
An actuating assembly with a handle that can be manually operated to unlock both the door lock and door holding lock in opposite directions, and can be electrically actuated by holding the handle, featuring a blocking mechanism with a blocking pin and locking device for the actuating lever to convert between manual and electric operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is provided for manual operation to unlock both door lock and door holding lock, then manual operation capability is improved, but the complexity of the actuating assembly increases due to additional blocking mechanisms and locking devices
Solution Approach 1:
The handle is designed to serve multiple functions: it can manually unlock both the door lock and door holding lock through bidirectional movement, and it can also be held to enable electrical actuation of the door element. This multi-functionality reduces the need for separate mechanisms for manual and electrical operation.
Solution Approach 2:
The actuating assembly incorporates dynamic blocking mechanisms that can switch between locked and unlocked states based on the operational mode. The blocking pin can be displaced to block or release the handle, and the locking device can secure or release the actuating lever, allowing the system to dynamically adapt between manual and electrical operation modes.
2Reliability
If blocking mechanisms and locking devices are added to enable manual operation, then the reliability of manual operation is improved, but the device complexity increases
Solution Approach 1:
The blocking pin is pre-positioned to automatically block the handle when the actuating lever is in the electrically actuated state, ensuring reliable manual operation only when needed. Similarly, the locking device is pre-configured to secure the actuating lever in the appropriate position for electrical operation, preventing unintended manual actuation.
Solution Approach 2:
The blocking pin and locking device act as intermediary elements that mediate between the handle and the door locks. These intermediaries control the transmission of manual forces to the locking mechanisms, ensuring reliable operation by enabling or disabling the connection based on the operational mode.
3Productivity
If the actuating assembly is designed for electrical actuation, then the productivity of door operation is improved, but the ease of manual operation deteriorates
Solution Approach 1:
The blocking pin is designed to be displaceable to dynamically change the operational state. When displaced to the blocking position, it prevents manual operation and enables electrical actuation for high-speed door closure. When returned to the unblocking position, it restores manual operation capability for emergency or auxiliary use.
Solution Approach 2:
The actuating assembly is segmented into distinct functional zones: a blocking mechanism for controlling manual access, a locking device for securing the actuating lever, and the handle for user interaction. This segmentation allows independent optimization of electrical and manual operation modes without compromising either.
