Fastening system and window shade including the same
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening systems for window shades often fail to securely hold panels, can cause tearing, and lack flexibility in use.
Innovation Solution
A fastening system comprising two clipping bases and two clipping plates, which can be configured to hold either two adjacent panels or a single panel, using teeth and holes for secure attachment and resilient hooks for easy assembly, allowing for flexible use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fasteners are used to attach panels to hangers, then the panels can be held and controlled, but the fasteners may not securely hold the panels and can cause tearing
Solution Approach 1:
The fastening system is divided into separate functional components: clipping bases attached to hangers, clipping plates that contact the panel, and resilient hooks that engage with slots. This segmentation allows each component to perform its specific function optimally without concentrating stress on a single attachment point, thereby securing the panel without causing tearing.
Solution Approach 2:
The resilient hooks are designed to be flexible and dynamic, allowing them to engage and disengage from the slots in the clipping plates. This dynamic characteristic enables the fastening system to adapt to panel movement and positioning adjustments while maintaining secure holding, and prevents rigid stress concentration that could cause panel tearing.
2Adaptability or versatility
If conventional fasteners are used, then panel attachment is achieved, but the system lacks flexibility in use
Solution Approach 1:
The resilient hooks can be easily engaged and disengaged from the slots, allowing users to quickly reconfigure the window shade by adding or removing panels. This dynamic engagement mechanism provides flexibility in use while maintaining ease of operation, as users can simply manipulate the resilient hooks to achieve desired configurations without complex tools or procedures.
Solution Approach 2:
The fastening system is designed to accommodate multiple panels through identical clipping bases and clipping plates, each capable of independent panel attachment. This universal design allows the same components to serve multiple functions across different panel positions, enabling flexible configuration while maintaining consistent ease of operation throughout the system.
3Reliability
If multiple clipping bases and clipping plates are used to hold adjacent panels, then secure attachment is achieved, but the device complexity increases
Solution Approach 1:
The fastening system uses identical, standardized clipping base and clipping plate components for each panel attachment point. This segmentation into modular, repeatable units provides secure attachment for multiple panels while keeping individual component complexity low. Each module is simple in design but collectively provides robust multi-panel securing capability.
Solution Approach 2:
The system maintains consistent geometric parameters and attachment mechanisms across all clipping bases and clipping plates. By standardizing component dimensions, slot positions, and engagement geometries, the patent achieves secure attachment for multiple panels without increasing the complexity of individual components, as each remains identical and simple in design.

AI summary
A fastening system for a window shade includes a first and a second clipping base, and a first and a second clipping plate. In a first configuration, the first and second clipping bases are attached to each other with each of the first and second clipping plates respectively disposed between and in contact with the first and second clipping bases, whereby a first panel can be held between the first clipping base and the first and second clipping plates and a second panel can be held between the second clipping base and the first and second clipping plates. In a second configuration, the first and second clipping bases are attachable to each other without the first and second clipping plates, whereby a single panel of a window shade can be held between the first and clipping bases.
