Elongate Profile Assembly With Frangible Section for Controlled Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elongate profiles with cutting patterns for bending are prone to incorrect bending during handling, storage, and manufacturing, leading to damage and increased production of defective products.
Innovation Solution
Incorporating a frangible separation section created by cutting lines that remain connected until intentionally broken, preventing unwanted bending and allowing for precise curvature adjustment after separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the profile is made bendable by creating notches, then the profile can be bent to desired curvature, but the profile becomes prone to incorrect bending during handling, storage, and manufacturing
Solution Approach 1:
The patent applies preliminary action by creating notches in advance during manufacturing while keeping the profile section connected via a frangible bridge. This allows the profile to be prepared for bending beforehand without actually becoming bendable until the bridge is broken, thus preventing incorrect bending during handling and storage while maintaining the capability to bend when needed.
Solution Approach 2:
The patent segments the profile into distinct sections connected by a frangible bridge that can be selectively broken. This segmentation allows the profile to maintain structural integrity during manufacturing and handling, while enabling controlled bending at specific locations after the bridge is broken, thus resolving the contradiction between bendability and resistance to incorrect bending.
2Ease of operation
If the profile section is removed to enable bending, then the profile can be bent without restriction, but the profile is vulnerable to damage during handling and storage before bending
Solution Approach 1:
The frangible bridge is prepared in advance during manufacturing, creating a controlled weakness that can be broken when needed. This preliminary preparation allows the profile to remain protected and rigid during handling and storage, while enabling easy bending operation after the bridge is broken, thus resolving the contradiction between ease of bending and vulnerability to damage.
Solution Approach 2:
The frangible bridge acts as an intermediary element between the profile sections. It provides a controlled mechanism that can be broken to enable bending, while its presence prevents incorrect bending during handling. This intermediary element resolves the contradiction by mediating between the need for bending capability and the need for protection against damage.
3Productivity
If the profile is made bendable during manufacturing, then bending can be performed immediately, but machines and equipment are at risk of damage from undesired bending
Solution Approach 1:
The notches are created in advance during manufacturing with the frangible bridge intact, preparing the profile for future bending without actually enabling bending at that moment. This preliminary action maintains profile rigidity during manufacturing operations, protecting machines from damage, while allowing quick bending later when the bridge is broken, thus resolving the contradiction between manufacturing speed and machine durability.

AI summary
The invention relates to an elongate profile extending in a longitudinal direction and having a first end and a second end, wherein between the first end and the second end the profile has at least one cutting line forming a cutting pattern for at least one profile section to be removed from the profile, wherein after removal of the at least one profile section from the profile the first end of the profile is bendable towards the second end of the profile and/or vice versa.
