Profile Rod Attachment via Beveled Overlaps and Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching profiles, particularly transoms, to rods in window frames are inefficient and lack a simple, effective means of ensuring a secure and aesthetically pleasing connection.
Innovation Solution
A method involving beveling overlaps on the profile and rod to facilitate precise alignment and connection, using beveled edges and notches to ensure a snug fit, followed by gluing or welding, which can include the use of Y-shaped or V-shaped heating elements for welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional connection methods are used to attach profile to rod, then the connection can be achieved, but the attachment process is complex and not easy to manufacture
Solution Approach 1:
The profile is inserted into a recess of the rod, creating a nested structure where one component fits within another. This nesting approach simplifies the attachment process by eliminating the need for separate fastening mechanisms, directly resolving the contradiction between ease of manufacture and device complexity
Solution Approach 2:
The recess is pre-formed in the rod with specific geometric features (beveled edges, notch) that guide and facilitate the insertion of the profile. This preliminary preparation of the receiving structure enables easy attachment without complex assembly steps, addressing the manufacturing ease versus complexity contradiction
2Reliability
If simple attachment methods are used, then the manufacturing is easier, but the connection is not secure and allows air and moisture penetration
Solution Approach 1:
The recess includes a notch specifically positioned to receive a sealing element, creating a localized sealing zone within the broader connection structure. This local quality enhancement ensures reliable sealing and prevents air/moisture penetration while maintaining overall manufacturing simplicity
Solution Approach 2:
A sealing element is introduced as an intermediary component between the profile and rod, filling the gap and preventing penetration. This mediator provides the necessary sealing function without complicating the basic attachment mechanism, resolving the contradiction between reliability and ease of manufacture
3Manufacturing precision
If overlaps are beveled to fit perfectly, then the connection precision is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The overlaps are pre-beveled during the profiling process to create complementary angles that naturally guide alignment during assembly. This preliminary geometric preparation ensures high precision connection without requiring complex alignment procedures or specialized tooling, resolving the contradiction between manufacturing precision and process complexity
