Polyhedral Clip Holder for Fast Roofing Hook Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage and presentation devices for hooks used in roofing elements are inefficient due to misalignment issues, preventing automation and causing significant time wastage in disentangling hooks during storage and extraction.
Innovation Solution
A polyhedral profile device with rigid faces that can be positioned within the hooks' loops, featuring a movable face that changes from a smaller space position for insertion to a holding position, allowing for automatic alignment and easy extraction of hooks, formed from a grooved blank that can be folded to create a rigid polyhedron.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hooks are stored in bulk without a specific storage device, then storage space is utilized, but hooks become entangled and cannot be extracted individually without manual disentanglement
Solution Approach 1:
The storage device divides hooks into individual compartments or slots, separating them from bulk storage. Each hook can be individually accessed and extracted without disturbing others, eliminating the need for manual disentanglement and significantly improving extraction speed.
Solution Approach 2:
The storage device acts as an intermediary between bulk hook storage and individual hook usage. It provides a structured interface that holds hooks in an organized manner, allowing quick individual extraction while maintaining efficient space utilization.
2Ease of operation
If a storage device is introduced into the hook loop, then individual extraction is enabled, but misalignment occurs during device introduction preventing automation
Solution Approach 1:
The device features an asymmetric profile with a specific geometric shape that matches the hook loop geometry. This asymmetric design ensures proper orientation during automated insertion, preventing misalignment issues while enabling individual hook extraction.
Solution Approach 2:
The device incorporates a movable face that can change position, allowing the device to adapt its geometry during the insertion process. This parameter change enables proper alignment with the hook loop even during automated operation, resolving the misalignment problem.
3Extent of automation
If a polyhedral profile with movable face is used, then automatic positioning is enabled and individual extraction is rapid, but device complexity increases
Solution Approach 1:
The polyhedral profile incorporates a movable face that can dynamically change position between a retracted state for automated insertion and an extended state for hook holding. This dynamic element enables automatic positioning functionality while maintaining a relatively simple overall device structure.
Solution Approach 2:
The device uses a polyhedral profile with a movable face that operates in a specific dimension, allowing automatic positioning through geometric transformation rather than complex mechanical mechanisms. This dimensional approach simplifies the device structure while achieving automation.

AI summary
The invention relates to a device for the storage and presentation of hooks (1) for fixing roofing elements, each hook (1) being formed of two divergent branches (2A, 2B) originating from a spring-like loop (3) tending to bring the branches (2A, 2B) together when they are under tension. This device is characterized in that it is in the form of a polyhedral profile (4) with rigid faces (5, 6, 7, 8), positionable in the loop (3) of the hook(s) (1) to be stored and presented, this profile (4) being provided with a movable face (7) between a position of least bulk of positioning of the profile (4) in the loop (3) of said hook(s) (1) and a position, called of holding of the hook(s) (1), in which the movable face (7) cooperates by support contact with the free edge of another face, called closing face (8) of the profile (4), to form a rigid polyhedron.
