Sliding Window Stabilization for Rattle-Free Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window stabilization mechanisms for work vehicles fail to effectively suppress windowpane rattling and ensure smooth locking, particularly due to inadequate sealing and support mechanisms when the window is closed.
Innovation Solution
A window stabilization mechanism comprising a rail, sliding member, seal mechanism, and lock mechanism, where the seal mechanism includes an elastic body with an internal space and additional elastic bodies strategically positioned to manage pressure and prevent backlash, and a window support member that presses the windowpane obliquely to enhance locking and reduce rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional elastic bodies are provided in the seal mechanism, then sealing performance is improved, but pressure builds up near the lock mechanism causing locking issues
Solution Approach 1:
The patent extracts (removes) the additional elastic body from the region adjacent to the lock mechanism. This creates a pressure relief zone that prevents excessive pressure buildup during window closing, ensuring smooth locking operation while maintaining sealing effectiveness in other regions through the remaining elastic body configurations.
Solution Approach 2:
The patent applies different sealing configurations to different regions of the seal mechanism. The additional elastic bodies are strategically positioned in regions away from the lock mechanism to provide enhanced sealing where needed, while leaving the lock-adjacent region with reduced elasticity to maintain low pressure and ensure reliable locking.
2Device complexity
If the window stabilization mechanism is simplified, then device complexity is reduced, but windowpane rattling suppression becomes inadequate
Solution Approach 1:
The window support member is designed to perform multiple functions simultaneously: it supports the windowpane weight, suppresses rattling through strategic positioning, and assists in guiding the window during closing. This multi-functionality achieves effective stabilization without adding complex separate components.
Solution Approach 2:
The seal mechanism acts as an intermediary element that provides both sealing and stabilization functions. By incorporating additional elastic bodies in specific regions, the seal mechanism mediates between the windowpane and cabin frame to suppress rattling while maintaining the primary sealing function, avoiding the need for separate stabilization components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism effectively suppresses windowpane rattling and ensures smooth locking by strategically placing additional elastic bodies in the seal mechanism and using a window support member to restrict movement, improving the overall stability and operation of the window when closed.
Implementation Method 1
The seal mechanism includes a seal frame body and a first additional elastic body. The seal frame body is an elastic body and has an internal space.
Implementation Method 2
The first additional elastic body is provided in the internal space of the seal frame body
Implementation Method 3
The window support member is configured to abut on the windowpane when the window is closed, and to press the windowpane in an oblique direction from the windowpane toward the rail

AI summary
A window stabilization mechanism includes a rail provided on a first cabin frame provided on one side of a window, and has a first end and a second end opposite to the first end in the lengthwise direction of the rail. A sliding member is provided on a windowpane and is configured to slide on the rail. The sliding member is located at a first end when the window is opened and at a second end when the window is closed. A lock mechanism is configured to lock the windowpane to the first cabin frame when the window is closed. A window support member is configured to abut on the windowpane when the window is closed, and to press the windowpane in an oblique direction from the windowpane toward the rail and from the second end toward the first end when the windowpane is locked by a lock mechanism.
