Window Profile Guide Groove Lateral Rod Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door fitting systems require lengthy assembly times and are uncomfortable to install, especially with long transmission rods, and suffer from instability and weak fixing mechanisms.
Innovation Solution
A window or door profile with a longitudinal guide groove and transmission rod design where the rod can be inserted from the front and is securely housed, eliminating the need for additional clipping and allowing symmetrical assembly, along with a fixing mechanism like screws for easy adjustment and enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transmission rod is inserted from the longitudinal end and driven in translation, then the rod can be installed completely in the groove, but the assembly time becomes relatively long and the installation becomes uncomfortable
Solution Approach 1:
Instead of inserting the rod from the longitudinal end and driving it in translation, the invention inverts the insertion direction by introducing the rod from the lateral side through the insertion space between the flanges and inner side walls. This allows the rod to be installed completely in the groove in a single straightforward motion, significantly reducing assembly time and improving installation comfort.
2Device complexity
If the rod and accessory have an asymmetrical shape for front mounting, then the assembly is simplified, but part of the rod must protrude from the guide groove and the fitting becomes unstable
Solution Approach 1:
The invention inverts the conventional front mounting approach by enabling lateral insertion of the rod while maintaining symmetry. The rod has identical lateral ends that are fully housed inside the guide groove between the bottom wall and lower internal surfaces, eliminating the need for protrusion and ensuring stability without sacrificing assembly simplicity.
Solution Approach 2:
While the rod itself is symmetrical, the invention uses asymmetrical positioning of the insertion space and flange configuration to enable unidirectional lateral insertion. The insertion space is defined by specific geometric relationships between flanges and inner side walls, creating an asymmetrical access path that guides the rod into proper position while maintaining overall symmetrical appearance and stability.
3Reliability
If clipping is provided on the accessory to prevent tearing, then the fitting is fixed on the groove, but the fixing remains relatively weak and requires additional components
Solution Approach 1:
The invention extracts and eliminates the need for additional clipping components by designing the guide groove structure itself to provide inherent retention. The flanges with lower internal surfaces and the insertion space geometry work together to securely hold the rod's lateral ends, providing strong fixing without requiring separate clipping elements.
Solution Approach 2:
The guide groove structure serves itself by using its own geometric features (flanges, inner side walls, and insertion space) to provide the retention function. The rod is retained by the natural configuration of the groove components rather than requiring external clipping mechanisms, making the system self-sufficient and more reliable.
4Ease of operation
If the transmission rod is inserted from the longitudinal end, then the rod can be installed, but the number of accessory references must be multiplied for left and right configurations
Solution Approach 1:
The invention uses asymmetrical design of the insertion space and flange configuration to enable unidirectional lateral insertion that works for all orientations. The specific geometric arrangement of flanges and inner side walls creates a universal interface that accommodates both left and right configurations with a single rod design, eliminating the need for multiple reference-specific accessories.
Solution Approach 2:
The rod with identical lateral ends and the symmetrical guide groove structure create a universal fitting system that can be installed in any orientation without requiring different rod configurations. This multi-functional design allows the same rod and groove assembly to serve both left and right applications, reducing the number of accessory references needed.
