Roman Blind Batten Assembly for Secure Fabric and Line Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing batten assemblies for Roman blinds lack a secure and adjustable mechanism for guiding control lines, leading to inconsistent loop formation and potential fabric removal during operation.
Innovation Solution
A batten assembly with an elongate hollow body featuring axial slots, a transverse wall dividing the body into clip and fabric cavities, and deformable walls to grip fabric, along with clips that can be securely rotated into position to guide control lines, ensuring fabric retention and adjustable spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single hollow batten body with fabric slot is used, then the structure is simple, but the mechanism to securely guide and retain fabric folds and control lines is insufficient
Solution Approach 1:
The batten body is divided into two separate cavities by a transverse wall: a fabric cavity for accommodating fabric folds and a clip cavity for retaining control line clips. This segmentation allows each cavity to be optimized for its specific function, providing secure retention mechanisms for both fabric and control lines while maintaining a relatively simple overall batten structure.
2Reliability
If deformable walls are added to grip fabric, then fabric retention is improved, but manufacturing complexity increases
Solution Approach 1:
The batten walls are designed with deformable characteristics that allow them to flex and grip fabric folds when subjected to insertion forces. This parameter change in wall rigidity enables secure fabric retention through the natural deformation properties of the material, avoiding the need for complex mechanical gripping mechanisms and keeping the manufacturing process relatively straightforward.
3Reliability
If clips are made resilient metal to snap over batten, then clip retention is improved, but precision of line guidance deteriorates
Solution Approach 1:
The clips are designed with resilient metal properties that allow them to dynamically adapt to the batten body contours while snapping into place. The elasticity of the metal clips provides strong retention force while their flexible nature allows for precise positioning and alignment, resolving the contradiction between retention strength and guidance precision.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure and adjustable mechanism for guiding control lines, preventing fabric removal and allowing for consistent loop formation, enhancing the operational reliability and appearance of Roman blinds.
Implementation Method 1
The walls may be parallel with inturned flanges, but the purpose of both versions is to render the walls deformable so as to grip the inserted fabric and prevent its removal from the cavity.
Implementation Method 2
The insertable part may be a stem with a cam surface capable of engaging with the edges of the body which define the clip slot.
