Pivotable Securing Handle with Pre-loaded Latch Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles lack a reliable and user-friendly securing device for openable side windows that clearly defines locked and unlocked positions, making it difficult for users to confirm the window is securely locked.
Innovation Solution
A pivotable securing handle with a pre-loaded latch arm and functional element, such as a pin, that interacts with a latch counterpart, featuring a spring device and specific path of travel, along with a sliding plate and ramp sections to ensure clear definition of the locked position and low operation forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional securing device is used, then the side window can be locked, but the locked position cannot be clearly recognized by the user
Solution Approach 1:
The patent employs visual indicators (such as colored elements or positional visibility changes) on the securing handle to clearly indicate when the locked position has been achieved. This allows users to immediately recognize the locked state without ambiguity, resolving the contradiction between reliable locking and clear position recognition.
2Ease of operation
If a simple securing mechanism is used, then the device is easy to operate, but the locking position is not clearly defined
Solution Approach 1:
The patent incorporates feedback mechanisms including visual indicators and tactile stops that provide immediate confirmation to the user when the locked position is reached. The securing handle includes indicators that change position or visibility state, giving real-time feedback on the locking status while maintaining simple operation.
3Ease of operation
If a pre-loaded functional element is added to clearly define the locked position, then position recognition is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the pre-loaded functional element (such as a spring-loaded indicator or positioning mechanism) directly into the securing handle structure, merging multiple functions into a single integrated component. This reduces overall device complexity while still providing clear locked position recognition through the pre-loaded element's engagement state.

AI summary
An openable side window for a motor vehicle is provided having an openable side window which covers a lateral vehicle opening when in its closed position and can be locked by a securing device, the securing device comprising a pivotable securing handle which can be pivoted between an unlocked position and a locked position and has an operating arm and a latch arm which, when in the locked position, interacts with a latch counterpart, wherein the latch arm comprises a functional element which is pre-loaded radially outward with respect to a pivot axis of the securing handle.
