Sliding Window and Door Guide Adjustment for Perpendicular Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sliding windows and doors face issues such as thick frames, sealing problems due to high forces not being applicable to the window/door seal, and the need for seals to move over the seal when opening/closing, leading to usability and security concerns.
Innovation Solution
A mechanism for sliding windows/doors with adjustable upper and lower guides that allow the sliding sash to open or close perpendicular to the opening direction, using rollers that roll over a rail, pivoting, or parallel movement to minimize friction and enhance sealing, enabling easy operation and improved tightness without visible frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional sliding window mechanisms are used, then the window can be opened and closed, but thick frames are required to accommodate the rollers and mechanisms
Solution Approach 1:
The invention transitions from traditional horizontal sliding to vertical sliding motion, allowing the sash to move up and down within the frame. This dimensional change eliminates the need for thick side frames to accommodate horizontal rolling mechanisms, as the guide elements are integrated into the top and bottom rails instead
Solution Approach 2:
The invention extracts the rolling function from the side frames and relocates it to the top and bottom rails. The guide rollers are mounted on the sash and roll along the vertical guide rails, separating the guidance function from the side frame structure and enabling thinner overall framing
2Reliability
If traditional sliding seals are used, then sealing is provided, but high forces cannot be applied to the seal and the seal must move over the sealing surface causing friction and wear
Solution Approach 1:
Instead of the seal moving across the sealing surface during operation, the invention inverts the approach by having the seal remain stationary on the frame while the sash moves vertically. The seal is compressed between the stationary frame and the moving sash, creating effective sealing without the seal itself experiencing sliding friction
Solution Approach 2:
The invention introduces a compression-based sealing mechanism where the seal acts as a compliant intermediary between the rigid frame and sash. The seal deforms under compression to fill gaps and create a tight seal, rather than relying on friction-based contact during sliding motion
3Ease of operation
If traditional sliding mechanisms are used, then opening and closing is possible, but security against accidental opening is compromised
Solution Approach 1:
The invention incorporates a counterweight mechanism that balances the weight of the sash, allowing easy opening and closing operation. The counterweight offsets the gravitational force on the sash, reducing the effort needed to move it while maintaining controlled motion that prevents accidental opening
