Solution Overview
Problem
Conventional window shades with multiple cells have complex constructions and are not cost-effective to manufacture, and they often fail to collapse and expand properly, affecting thermal insulation and appearance.
Innovation Solution
A window shade panel assembly featuring a support sheet with elongate strips that form cells, where each strip has folding lines for easy collapse and expansion, and bonding techniques allow for simple construction and cost-effective manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional window shades use multiple cells formed by overlapping transversal strips, then thermal insulation performance is improved, but construction complexity increases and manufacturing cost-effectiveness deteriorates
Solution Approach 1:
The panel is divided into multiple cells formed by longitudinal and transversal strips that are bonded to the support sheet. Each strip is segmented with folding lines that allow independent collapse and expansion, simplifying the overall construction while maintaining thermal insulation through the multi-cell structure.
Solution Approach 2:
The patent combines longitudinal and transversal strips into a unified panel assembly where both types of strips are bonded to the same support sheet. This merging approach reduces construction complexity compared to separate overlapping strip assemblies while achieving equivalent thermal insulation through the integrated cell structure.
2Shape
If conventional window shades use complex multi-strip constructions, then cell formation is achieved, but manufacturing cost-effectiveness deteriorates
Solution Approach 1:
The strips are pre-formed with folding lines before being bonded to the support sheet. This preliminary action simplifies the manufacturing process by pre-preparing the strips for easy assembly and collapse/expansion, reducing the complexity of on-site construction while maintaining proper cell formation.
Solution Approach 2:
The patent uses flexible strips with folding lines that can be easily bonded to the support sheet and collapsed/expanded as needed. This use of flexible, pre-scored strips simplifies manufacturing compared to rigid multi-layer constructions, making the process more cost-effective while achieving the required cell structure.
3Stability of the object's composition
If cells are rigidly constructed, then structural stability is maintained, but ability to collapse and expand deteriorates
Solution Approach 1:
The strips are constructed with folding lines that allow dynamic collapse and expansion while maintaining structural stability during the shaded position. The folding lines enable the cells to transition between expanded and collapsed states, providing adaptability without compromising the stability of the panel in its normal operational state.
Solution Approach 2:
The folding lines are strategically positioned at specific locations along the strips to provide localized flexibility. This local quality approach allows the cells to collapse and expand at designated points while maintaining overall structural stability, achieving both adaptability and stability simultaneously.

AI summary
A panel assembly for a window shade includes two elongate strips made of a single material layer that are bonded to a support sheet having a multilayer structure. Each elongate strip has a first and a second edge, and a main strip portion between a first and a second margin, the first and second margin respectively adjoining the main strip portion along a first and a second folding line, the first margin extending between the first folding line and the first edge, the second margin extending between the second folding line and the second edge and including a third folding line. The first margin of each elongate strip is bonded to the support sheet, and the second margin of a first elongate strip is bonded to a second elongate strip at a first margin portion between the third folding line and the second edge of the first elongate strip.
