Foldable Covering Curtain Structure for Compact Trunk Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covering curtains for automobile interiors protrude when rolled up, disturbing rear trunk space, especially when large luggage is placed, and are difficult to store when detached.
Innovation Solution
A foldable and retractable covering curtain design featuring two outer tubes connected by a rotating structure, with a zipper mechanism and side tube plugs, allowing the curtain to be folded along the length direction of the tubes for compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the covering curtain is rolled up, then the curtain can be retracted, but the handle part and curtain body protrude forward disturbing rear trunk space
Solution Approach 1:
The curtain body is nested within the telescopic tube structure, with the handle part and curtain body contained inside the tube when retracted, eliminating protrusion and allowing compact storage in the rear trunk
Solution Approach 2:
The telescopic tube structure allows dynamic adjustment of the curtain length, enabling the curtain to be extended when needed and retracted to a compact size for storage, transforming the static curtain into a dynamically adjustable system
2Adaptability or versatility
If the covering curtain is detached for larger luggage, then the curtain can be removed, but the detached curtain is difficult to store due to its length
Solution Approach 1:
The detached curtain can be stored by nesting it within the telescopic tube structure, which provides a compact storage container that accommodates the full-length curtain when not in use, eliminating the storage difficulty of long detached curtains
Solution Approach 2:
The curtain system is segmented into modular components including the telescopic tube, handle part, and curtain body, allowing the curtain to be detached and stored within the tube structure, providing flexibility for luggage space while maintaining easy storage capability
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
Enables the retracted curtain to occupy a small space, making it easy to store and reducing obstruction in the rear trunk, while maintaining aesthetic and practical functions.
Implementation Method 1
a spring (13) arranged between an inner end face of the gear end cover (14) and an inner wall end face of the inner cavity
Implementation Method 2
the first round mounting boss is provided with a first annular gear groove structure in a position corresponding to the inner cavity, and the second round mounting boss is provided with a second annular gear groove structure in a position corresponding to the inner cavity, the first and second annular gear groove structures are centrally arranged in forward and backward directions to form an integral annular gear groove, a gear end cover is engaged in the annular gear groove, the gear of the gear end cover is meshed with the gear groove of the annular gear groove

AI summary
A foldable and recyclable covering curtain, that can be folded along a length direction, which includes outer tubes and inner ends of the outer tubes connected by a rotating structure. The outer tubes are folded or opened into a straight line by the rotating structure, and one side of each outer tube is provided with an interval groove. The curtain includes a curtain fabric provided inside each outer tube, and the curtain fabrics extend outward to the outer tube by the interval groove. When the curtain fabric is unfolded, opposite sides of the curtain fabrics are closed using a zipper mechanism. When the curtain fabric is folded, the zipper mechanism is opened. Two sides of the outer end of each curtain fabric in the unfolded state are provided with a pair of side tube plugs, and each pair of side tube plugs is inserted with a corresponding side tube.
