Drapery Track Splice Structure for Precise Section Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Long drapery tracks are typically shipped in sections rather than as a single piece, requiring a reliable and easy-to-install splice structure to ensure proper operation and movement of master and auxiliary cars along the track length.
Innovation Solution
An elongated rectangular splice structure with circular holes and screws that align and secure track portions together, providing longitudinal force and preventing rotation, allowing for easy assembly and alignment of drapery system components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drapery track is shipped as a single pre-assembled piece, then the operational reliability is improved, but the shipping cost and storage requirements increase significantly
Solution Approach 1:
The drapery track is divided into multiple modular sections that can be shipped separately and assembled on-site using the splice structure. This segmentation reduces shipping volume and storage requirements while maintaining the functionality of the complete track system.
Solution Approach 2:
The splice structure acts as an intermediary component that connects separate track sections together. This mediator enables the assembly of multiple sections into a continuous track, achieving the same operational reliability as a pre-assembled track while allowing for compact shipping.
2Volume of stationary object
If the drapery track is shipped in sections requiring assembly, then the shipping cost and storage requirements are reduced, but the alignment precision and operational reliability deteriorate
Solution Approach 1:
The splice structure includes pre-formed alignment features such as guide channels and positioning surfaces that ensure accurate alignment of track sections during assembly. This preliminary preparation of alignment mechanisms eliminates the need for complex field adjustments and ensures precise connection between sections.
Solution Approach 2:
The splice structure incorporates self-aligning features where the geometry of the splice channels and positioning surfaces automatically guides the track sections into correct alignment during assembly. This self-service alignment mechanism reduces dependency on external alignment tools and skilled labor.
3Strength
If the splice structure uses multiple fastening points, then the connection strength is improved, but the device complexity increases
Solution Approach 1:
The splice structure combines multiple fastening points and alignment features into a single integrated component. This merging of functions into one splice piece maintains high connection strength through multiple attachment points while avoiding the complexity of assembling multiple separate fastening components.

AI summary
A drapery system comprises an elongated track having two track portions and an elongated rectangular splice structure for coupling the two track portions together. Each track portion has a splice channel and at least one track hole located in the splice channel. The splice structure has at least two splice holes extending through the splice structure and is adapted to be received within the splice channels. Screws are received through the splice holes and extend into the track holes in a direction perpendicular to the splice structure. The distance between the two splice holes is less than the distance between the two track holes when the two track portions are aligned adjacent each other and the screws are not installed. Each of the screws contacts an edge of the respective track hole to provide a longitudinal force on the respective track portion when the screws are installed in the splice holes and track holes, such that the track portions are forced together.
