Vehicle Cargo Cover with Adjustable Intermediary Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo space covers for vehicles lack adaptability in intermediary position settings, which are fixed and not customizable to user requirements or loading situations.
Innovation Solution
A cargo space cover system featuring a roller blind with a tension rod and separate positioning drive, allowing for adjustable intermediary positions through a motor control system, enabling users to define opening widths based on personal convenience or loading needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a guide is used to move the cargo space cover into an intermediary position, then access to the cargo space is improved, but the intermediary position is fixed and not adaptable to user requirements
Solution Approach 1:
The patent applies the dynamics principle by replacing the fixed mechanical guide with an electric motor drive system that can dynamically position the cargo space cover at multiple adjustable intermediary positions. The motor drive allows the cover to be stopped at any position along its travel path, transforming the static intermediary position into a dynamic, user-adjustable feature that adapts to different access requirements and cargo configurations.
2Ease of operation
If a motor drive is used to tighten the cargo space cover, then the cover can be moved between positions, but the position is exactly defined by the guide rather than being user-selectable
Solution Approach 1:
The patent applies mechanics substitution by replacing the mechanical guide system that defines fixed positions with an electric motor drive system. This substitution eliminates the physical constraints of the guide and allows electronic control of the cover position, enabling users to select and adjust intermediary positions according to their specific needs rather than being limited to pre-defined mechanical stops.
3Reliability
If the cargo space cover is returned to cover position during hatch closing, then cargo coverage is maintained, but loading situations cannot be adapted without user intervention
Solution Approach 1:
The patent applies feedback by implementing an automated system that can detect loading situations and automatically adjust the cargo space cover position accordingly. The motor drive system receives control signals based on detected cargo configurations and autonomously positions the cover at appropriate intermediary positions, eliminating the need for user intervention while maintaining reliable cargo coverage when needed.

AI summary
A cargo space cover for vehicles including a roller blind which is fixated with a first edge at a winding shaft and which includes a tension rod at a second edge that is remote from the winding shaft; a winding shaft drive which acts against a pull out movement of the roller blind and which moves the roller blind from a pulled out position into a pulled in position; and a support device which cooperates with the tension rod and by which the roller blind is movable into an intermediary position that releases a vehicle cargo space at least partially, wherein a positioning drive is provided in addition to the winding shaft drive, wherein the positioning drive moves the tension rod which moves the roller blind into at least one intermediary position.
