Solution Overview

Problem

Existing flexible containers, such as sacks, struggle to snugly fit objects due to protruding bays and cumbersome closure mechanisms, especially when transporting irregularly shaped items like people, where external belts are uncomfortable and ineffective.

Innovation Solution

A flexible container with a tapering mechanism featuring zigzag-shaped cable pulls that guide through spaced cable guides, allowing the container to adjust its circumference by pulling the sides together, creating a snug fit and facilitating easier retrieval.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If external belts are used for closure, then the container can be closed, but the closure becomes cumbersome and uncomfortable

Engineering Contradiction:

Improveclosure operationVSAvoidclosure mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The closure function is extracted from external belts and integrated into the container structure itself through internal cable pulls that run through channels in the container walls, eliminating the need for separate external closure components

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cable pull mechanism is nested within the container structure, with cables running through internal channels and guides embedded in the container walls, creating a compact integrated closure system

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If flexible material is used for the container, then the container can adapt to objects, but protruding bays prevent snug fitting

Engineering Contradiction:

Improveadaptation to objectVSAvoidcontainer surface

Core Design Contradiction:

Adaptability or versatilityVSShape

Solution Approach 1:

The container surface is modified with localized cable guide channels and narrowing surfaces at specific locations where closure is needed, allowing the flexible material to maintain its overall adaptability while providing localized structural features for snug fitting

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The container incorporates dynamic cable pull mechanisms that can be adjusted to different tension levels, allowing the narrowing surface to dynamically adapt its shape to match the object being enclosed

Inventive Principle:

Principle #15Dynamics

3Productivity

If the container is made tight-fitting, then transportation efficiency improves, but retrieval becomes difficult

Engineering Contradiction:

Improvetransportation efficiencyVSAvoidretrieval operation

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The cable pull mechanism is designed to be easily accessible from the outside, allowing users to quickly release the tension and open the container without needing to access internal components or perform complex operations

Inventive Principle:

Principle #25Self-service

AI summary

The invention relates to a container (1) with a tapering mechanism (2), the container (1) being designed to be flexible and intended to enclose an object in its interior, the tapering mechanism (2) having at least two pulling sides (21, 22 ) a tapering surface (23) of the container (1) by means of at least one cable (31, 32) to reduce the circumference of the interior of the container (1) can be pulled towards one another, the cable of the cable (31, 32) being alternately is guided on the opposite pulling sides (21, 22) by cable guides (33) arranged next to one another along the pulling sides (21, 22) and spaced apart from one another.
