Flexible Plastic Strip with Fold Lines for Profile Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional plastic profiles are bulky, difficult to store and handle, require complex cutting and gluing, and offer too many standardized options, leading to user confusion and inefficiencies in storage and installation.
Innovation Solution
A flexible, elongated strip with fold lines along its longitudinal axis, made of plastic material, that can be cold-deformed to form stable profiles of various shapes and sizes, including adhesive coverage for easy attachment, reducing material waste and maintaining mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If profiles are produced with large longitudinal dimensions, then they can cover longer distances, but they become bulky and difficult to store and handle
Solution Approach 1:
The profile is segmented into multiple straight sections connected by flexible joints, allowing the long profile to be divided into manageable segments that can be easily stored and handled while still covering long distances when assembled
2Adaptability or versatility
If profiles are produced in many different shapes, then they can meet diverse user needs, but it requires developed storage and referencing logistics and confuses users
Solution Approach 1:
A single universal strip design with integrated fold lines can be folded into multiple different profile shapes (L-shape, U-shape, Z-shape, etc.), allowing one product to serve multiple functions and eliminating the need for separate products for each profile type
3Ease of manufacture
If profiles are provided without adhesive, then the material remains pure plastic, but a complex gluing step is necessary for installation
Solution Approach 1:
The adhesive function is merged with the plastic strip itself by applying an adhesive layer directly onto the strip surface, combining the structural element and the bonding element into a single integrated component that simplifies installation
