Panelless Vehicle Cargo Screen with Flexible Wire Member

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing cargo screens for vehicles protrude when wound, reducing storage capacity and requiring additional space, due to the thickness of the knob panel member being greater than the screen member, leading to inefficiencies in space usage and manufacturing complexity.

Innovation Solution

A cargo screen design featuring a housing unit with a screen drawing groove and a screen unit with a flexible wire member coupled to the screen member, including protruding members and screen guide members, which allows the screen to be wound without protrusion by using a cylindrical rotation shaft system and flexible material, reducing the thickness and weight of the screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a panel member with a knob is used for the cargo screen, then the screen can be operated to deploy and wind, but the panel member protrudes when wound due to its greater thickness compared to the screen member

Engineering Contradiction:

Improveoperation of cargo screenVSAvoidprotruding portion when wound

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The cargo screen is divided into two distinct components: a thin screen member for blocking visibility and a separate panel member with a knob for operation. The screen member is designed to wind completely into the housing unit, while the panel member is positioned separately at the rear end, eliminating the protrusion problem by segmenting the functional elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A wire member is introduced as an intermediary element to connect the panel member to the screen member. This wire member transmits the operating force from the knob to the screen member, enabling remote operation while allowing the screen member to wind independently without the panel member protruding.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the cargo screen is designed with a thick panel member for operation, then it provides sufficient operating leverage, but it requires additional space when wound reducing storage capacity

Engineering Contradiction:

Improveoperating leverageVSAvoidstorage capacity of luggage room

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The operational function is separated from the screening function. The thin screen member handles the screening task and winds completely into the housing unit, maximizing storage capacity. The panel member with knob handles operation and is positioned separately, eliminating the need for additional winding space.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The panel member is repositioned from the front end to the rear end of the housing unit, utilizing the longitudinal dimension of the housing. This spatial reconfiguration allows the screen member to wind fully into the housing volume without the panel member occupying winding space, effectively using available space in a different dimension.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A cargo screen device for a vehicle may include a housing unit which has a screen drawing groove, and a screen unit which includes a screen member that may be wound in the housing unit, or deployed from the housing unit through the screen drawing groove, wherein the screen unit includes a wire member which may be made of a flexible material, and coupled to the screen member along a tip of the screen member.
