Solution Overview

Problem

Existing suitcases lack convenient access to personal items like cups, magazines, and mobile phones, and the addition of cup holders can compromise the aesthetic appeal and overall design.

Innovation Solution

A draw bar structure with a multifunctional bracket that includes a foldable design with a fork frame, bottom support, and elastic mechanisms, allowing for the creation of functional surfaces for item placement without affecting the suitcase's appearance, featuring adjustable and retractable components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If cup holders and similar structures are added on the suitcase body, then personal items can be conveniently placed and accessed, but the overall aesthetic appearance and sense of line of the suitcase is affected

Engineering Contradiction:

Improveconvenience of accessing personal itemsVSAvoidaesthetic appearance and sense of line

Core Design Contradiction:

Ease of operationVSShape

Solution Approach 1:

The bracket is divided into multiple functional parts: a first bracket portion fixed to the drawbar, a second bracket portion that can rotate relative to the first, and a third bracket portion that can rotate relative to the second. This segmentation allows each part to perform specific functions while maintaining overall aesthetic appearance when folded.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bracket employs dynamic elements including rotation joints between different bracket portions, allowing the bracket to change its configuration between folded (aesthetic) and unfolded (functional) states. The rotation capability enables the bracket to adapt between maintaining appearance and providing accessibility.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a multifunctional bracket with functional surfaces is added to the drawbar, then storage and placement functions are improved, but the structural complexity of the suitcase increases

Engineering Contradiction:

Improvestorage and placement functionalityVSAvoidstructural complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The bracket is designed as a multifunctional component that can: (1) support personal items on its functional surfaces, (2) rotate to different positions, (3) fold to maintain aesthetic appearance, and (4) integrate with the drawbar structure. This multi-functionality consolidates multiple features into a single component.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The bracket portions are nested within each other when folded - the second bracket portion rotates to be positioned within or alongside the first, and the third bracket portion rotates to be positioned within or alongside the second, creating a compact nested configuration that minimizes visual impact.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Shape

If the bracket is designed as a foldable structure, then the aesthetic appearance is maintained when not in use, but the ease of operation for deploying and folding increases complexity

Engineering Contradiction:

Improveaesthetic appearance when not in useVSAvoidease of deploying and folding

Core Design Contradiction:

ShapeVSEase of operation

Solution Approach 1:

The bracket employs elastic mechanisms that automatically push the bracket portions into their folded positions, reducing the effort required by the user. The elastic force provides automatic return-to-fold functionality, making the operation simpler despite the multiple rotation joints involved.

Inventive Principle:

Principle #25Self-service
