Solution Overview

Problem

Existing carrying systems for portable outdoor furniture, such as foldable chairs and umbrellas, are cumbersome, prone to damage, and often require multiple trips due to their inability to securely accommodate multiple items simultaneously.

Innovation Solution

A flexible carrying strap system with adjustable loops and a padded sleeve that allows for the simultaneous transport of multiple items, including foldable furniture and personal items, and includes a charging module for electronic devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional storage bags are used to carry foldable chairs, then the chairs can be transported, but the bags are easily torn by sharp edges and corners, requiring frequent replacement

Engineering Contradiction:

Improvedurability of carrying systemVSAvoidcost of replacement

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The invention extracts the protective function from the traditional fabric bag and creates a separate rigid protective structure. The frame protector with receiving cavity encapsulates the folded chair, while the carrying bag only needs to contain this protected unit, reducing stress on the bag material from sharp edges and corners.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention applies beforehand cushioning by incorporating a rigid protective frame that prevents damage before the chair is placed in the carrying bag. The frame protector absorbs and distributes mechanical stresses, preventing the bag from being torn by sharp edges and corners during insertion and transport.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

2Productivity

If multiple items are carried separately, then each item can be transported, but multiple trips are required, increasing time and effort

Engineering Contradiction:

Improvetransport efficiencyVSAvoidtime for multiple trips

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The invention merges multiple items into a single integrated carrying system. The frame protector can accommodate the folded chair along with associated items like umbrellas and bags within its receiving cavity, while the carrying bag holds this consolidated unit, eliminating the need for multiple separate trips.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The carrying system is designed with multi-functionality to transport various combinations of items. The frame protector's receiving cavity and the carrying bag can accommodate different configurations of foldable furniture and related accessories, making the system universal for multiple transport needs in a single trip.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If foldable chairs are placed in carrying bags without protection, then they can be transported, but the sharp edges and corners damage the fabric sleeves

Engineering Contradiction:

Improveease of loadingVSAvoiddamage to carrying bag

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention introduces an intermediary protective structure (frame protector) between the sharp edges and corners of the folded chair and the fabric carrying bag. This mediator absorbs the mechanical stress and prevents direct contact between harmful elements and the bag material, eliminating fabric damage while maintaining ease of loading.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Adaptability or versatility

If traditional carrying bags are used, then single items can be carried, but multiple items cannot be accommodated simultaneously

Engineering Contradiction:

Improvecapacity for multiple itemsVSAvoidstructure of carrying system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention applies the nested doll principle by creating a hierarchical structure where the frame protector with its receiving cavity nests the folded chair and associated items, which are then nested within the carrying bag. This nested arrangement enables multiple items to be accommodated simultaneously while maintaining a compact, manageable system structure.

Inventive Principle:

Principle #7Nested doll (Nesting)
