Vertical Vane Clip with Living Hinge for Uniform Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vertical vane coverings for architectural openings lack a reliable and efficient mechanism for uniformly suspending and connecting vertical vanes to carriers, particularly in transitioning between extended and retracted positions, and in maintaining aesthetic uniformity during operation.
Innovation Solution
A semi-rigid but pliant clip with a movable design featuring a locking post and pin mechanism, allowing the clip to pivot between open and closed positions, and a neck for connection to the headrail, ensures secure attachment and detachment of vanes from carriers, facilitating uniform suspension and easy stacking for transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid clip structure is used to securely suspend vanes, then the reliability of vane suspension is improved, but the ease of operation for connecting and disconnecting vanes deteriorates
Solution Approach 1:
The clip is designed with a living hinge that allows it to dynamically change shape between open and closed positions. The semi-rigid but pliant material enables the clip to flex and return to its original shape, providing secure suspension when closed while allowing easy opening for connection and disconnection operations.
Solution Approach 2:
The clip's physical state changes between rigid (when closed for suspension) and flexible (when opening for connection). The semi-rigid but pliant material property allows the clip to change its rigidity parameter, providing both secure holding when closed and ease of manipulation when opening or closing.
2Ease of manufacture
If a simple clip design is used to reduce device complexity, then the ease of manufacture is improved, but the reliability of uniform vane suspension deteriorates
Solution Approach 1:
The clip is segmented into distinct functional parts: a neck for carrier connection, a living hinge for movement, and depending legs with locking mechanisms for vane retention. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity and manufacturability.
Solution Approach 2:
The living hinge provides self-service by automatically returning the clip to its closed position after opening, ensuring uniform suspension without requiring additional springs or complex mechanisms. The semi-rigid but pliant material itself provides the restoring force.
3Shape
If a fixed clip structure is used to maintain aesthetic uniformity, then the visual consistency is improved, but the ease of installation and removal deteriorates
Solution Approach 1:
The clip transitions from a static fixed structure to a dynamic structure that can open and close. When closed, it maintains a uniform aesthetic appearance consistent with fixed structures. When opened, it allows easy installation and removal operations through the living hinge mechanism.

AI summary
A removable clip for suspending a vane in a vertical vane covering for an architectural opening from a carrier in a control system comprises a neck for connection to the carrier and spaced downwardly projecting fixed and movable legs having a system for releasable interconnection. The movable leg is connected to the necks of the clip through a living hinge so as to be pivotal about the hinge between open and closed position. In the open position, a vane having a hole adjacent to the top edge thereof can be inserted into the clip connection thereto. The neck of the clip has an opening therethrough for suspension from a hook or ledge on the carrier.
