Foldable Vehicle Cargo Screen With Roller Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing cargo screens for vehicle luggage rooms lack adequate storage space, leading to difficulties in separately storing the screen when loaded with cargo, which hinders efficient cargo stacking and loading.
Innovation Solution
A cargo screen design featuring a foldable housing with a rotatable roller and cut central portion, allowing the screen to be wound around the roller and selectively unwound, with foldable left and right screen panels and fixing members to prevent winding into the housing, enabling the screen to be easily folded and stored within the luggage room.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cargo screen is detached and stored separately, then the cargo screen can be kept clean and organized, but there is no adequate storage space in the luggage room
Solution Approach 1:
The cargo screen is wound around the roller like a nested structure, with the screen panel inserted into the housing. This nesting arrangement allows the cargo screen to be compactly stored within the housing when not in use, eliminating the need for separate storage space while keeping the screen organized and protected.
Solution Approach 2:
The cargo screen transitions from a static, fixed structure to a dynamic, movable one. The screen can be wound around the roller for storage and unwound for use, allowing flexible adaptation between storage and operational states. This dynamic capability resolves the contradiction by enabling the screen to occupy minimal space during storage while maintaining full functionality during use.
2Ease of operation
If the cargo screen is left hanging or placed in any space, then it remains accessible, but it interferes with cargo stacking and loading efficiency
Solution Approach 1:
The cargo screen is extracted from its traditional fixed or hanging position and integrated into a dedicated storage system (roller within housing). This extraction allows the screen to be completely removed from the cargo space when not in use, eliminating interference with cargo stacking while maintaining accessibility when needed through the winding/unwinding mechanism.
Solution Approach 2:
The dynamic winding mechanism allows the cargo screen to transition between deployed and retracted states. When retracted into the housing, it clears the cargo space entirely, maximizing loading efficiency. When deployed, it provides the necessary screening function. This dynamic behavior resolves the contradiction between accessibility and loading efficiency.
3Volume of stationary object
If the cargo screen is made foldable with cut central portion, then space utilization is improved, but the structural complexity increases
Solution Approach 1:
The cargo screen is segmented into multiple components: the screen panel, the roller, and the housing. The screen panel itself is divided with a cut central portion that allows it to be folded and inserted into the housing. This segmentation enables compact storage while keeping each individual component relatively simple in structure, balancing space utilization with structural complexity.
