Curtain-blind
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curtain-blind systems face issues such as inadequate light blocking, cumbersome installation, and difficulty in replacing individual sections for maintenance, as well as offering minimal privacy in the light condition.
Innovation Solution
A curtain-blind system comprising adjustable sections with releasable connectors that allow for independent hanging and removal, featuring a hanger system with rotatable axes and a light-permeable third surface for optimal light control, enabling easy assembly, maintenance, and improved privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If blackout strips are spaced by translucent strips as in GB2549637, then privacy is improved in dark condition, but installation time increases and repair complexity increases
Solution Approach 1:
The curtain-blind is divided into multiple independently replaceable sections, each section being a self-contained unit that can be installed and removed separately. This segmentation allows faster installation compared to custom-made blinds and enables individual section replacement without removing the entire blind.
Solution Approach 2:
The standardized sections can be universally applied across different window sizes by simply adding or removing sections. The same section design serves multiple functions: light blocking, privacy provision, and easy replaceability, eliminating the need for custom measurements and assembly.
2Object-affected harmful factors
If blackout strips are spaced by translucent strips as in GB2549637, then privacy is improved in dark condition, but device complexity increases
Solution Approach 1:
The curtain-blind is divided into multiple independently replaceable sections, each section being a self-contained unit that can be installed and removed separately. This segmentation simplifies the overall system by breaking down the complex assembly into manageable, identical modules.
Solution Approach 2:
The system allows easy adjustment of the blind's overall dimensions by adding or removing sections, changing the parameter of coverage area without altering the fundamental design or requiring complex custom assembly.
3Ease of repair
If individual slats of Venetian blinds are replaced for cleaning or repairs, then maintenance is possible, but operation complexity increases and specialist assistance may be required
Solution Approach 1:
The curtain-blind is divided into multiple independently replaceable sections, each section being a self-contained unit that can be installed and removed separately. This segmentation enables individual section replacement without affecting other sections, simplifying maintenance operations.
Solution Approach 2:
Individual sections can be extracted from the overall blind assembly and replaced independently. This extraction capability allows users to remove only the soiled or damaged section for cleaning or repair, leaving the rest of the blind in place and operational.
4Object-affected harmful factors
If made-to-measure blinds are used to mitigate light haloing, then light blocking is improved, but manufacturing cost increases
Solution Approach 1:
The curtain-blind is divided into multiple independently replaceable sections, each section being a self-contained unit that can be installed and removed separately. This segmentation allows for standardized manufacturing of sections that can be configured to fit various window sizes, reducing custom manufacturing costs.
Solution Approach 2:
The system allows easy adjustment of the blind's overall dimensions by adding or removing sections, changing the parameter of coverage area without altering the fundamental design or requiring expensive custom manufacturing.

AI summary
A curtain-blind system has hangers which hang multiple sections thereof. Each section has a first surface, a second surface, a first connector clamping the first surface, and a second connector clamping the second surface. The first connector is releasably hung on a first hanger and the second connector is releasably hung on a second hanger. The sections are arranged side-by-side on respective hangers with the first connector of one section being independently releasable from an adjacent section whilst remaining clamped to the first surface. A hanger has a head portion received in a head-rail and a hanger portion depending below the head portion. The hanger portion is configured to releasably hold independent connectors of first and second sections such that the sections are hung adjacently on the hanger portion in a side-by-side arrangement.
