Sliding Window Assembly With Pivot Handle And Guide Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding window assemblies with jogged tracks are expensive to manufacture and prone to design defects, limiting the thickness of mobile elements to 2-6 millimeters, which complicates complete entry into the frame and results in poor sealing and noise/water infiltration.
Innovation Solution
A sliding window assembly with a pivot handle that allows for thicker mobile elements (2-18 mm) by using a frame with a track, a sliding window portion, and a handle pivotable between lock and slide positions, featuring guide pins and a locking assembly that enables flush closure and sealing, with transition regions guiding the pins into alignment with the track for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a jogged track is used for the sliding window assembly, then the window can be displaced to a flush configuration, but the manufacturing cost increases and the window closing becomes more difficult
Solution Approach 1:
The track is divided into multiple sections: a first section with a first inclination angle, a second section with a second inclination angle, and a third section with a third inclination angle. This segmentation allows each section to perform a specific function in the window closing sequence, simplifying the overall track design while maintaining ease of operation.
Solution Approach 2:
The curved guide surface is positioned to engage the guide pin before the window reaches the end of the track, preliminarily guiding the window into the correct alignment and orientation for flush closing. This preliminary action prevents misalignment and ensures smooth closing operation.
2Strength
If the mobile element thickness is increased beyond 6 millimeters, then the durability and functionality are enhanced, but the element cannot completely enter the frame opening during translation
Solution Approach 1:
A curved guide surface is introduced in the frame opening that follows a curved path to guide the guide pin. This curvature allows the thick mobile element to be rotated and repositioned during insertion, enabling complete entry into the frame opening while maintaining the strength benefits of increased thickness.
Solution Approach 2:
The system transitions from a static linear track to a dynamic multi-section track with varying inclination angles and a curved guide surface. This dynamic track configuration adapts during the insertion process, allowing the guide pin to follow a complex path that accommodates thicker elements while ensuring complete frame entry.
3Device complexity
If a linear track is used for the sliding window assembly, then the structure is simple, but the window cannot achieve flush closure and proper sealing
Solution Approach 1:
The track is segmented into multiple sections with different inclination angles, allowing the window to be guided through a precise sequence of movements that achieve both flush closure and proper sealing while maintaining a relatively simple overall structure.
Solution Approach 2:
The curved guide surface performs preliminary alignment and orientation of the window before it engages with the main track sections. This preliminary action ensures that the window is properly positioned to achieve flush closure and effective sealing without requiring a complex track design.

AI summary
A sliding window assembly includes a frame with a track, and a sliding window portion disposed in the frame and displaceable in the track between a closed position and an open position. The sliding window portion includes a handle pivotable between a lock position and a slide position, and a driving pin coupled with the handle and engaging the track. The driving pin defines a pivot axis for the handle. A guide pin spaced from the driving pin is selectively engageable with the track when the handle is pivoted from the lock position to the slide position. With the handle in the slide position, the sliding window portion is displaceable from its closed position to an open position.
