Solution Overview

Problem

Conventional towels lack effective wind protection during use, especially in windy conditions at beaches or pools, where they fail to isolate users from wind and sand.

Innovation Solution

A towel with an internal structure of hollow cylindrical pieces and strings that can be rearranged to form a rigid structure, allowing parts of the towel to be positioned vertically, creating a barrier against wind and sand, while maintaining flexibility for standard use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a towel is made flexible for standard use, then it is comfortable for drying and lying, but it cannot protect users from wind

Engineering Contradiction:
Improvecomfort for drying and lyingVSAvoidwind protection
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The towel incorporates a transformable internal structure that can switch between a collapsed flexible state for comfort and an expanded rigid state for wind protection. The hollow cylindrical pieces connected by strings can be compressed into a compact bundle within the towel fabric, then expanded upon activation to form a rigid barrier, allowing the same structure to serve both comfort and protection functions at different times

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rigid protective structure is nested within the flexible towel fabric. The hollow cylindrical pieces and string mechanism are contained inside the towel in a compressed state, allowing the towel to maintain its soft, flexible characteristics during normal use while housing the capability for rigid wind protection when activated

Inventive Principle:
Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If a rigid structure is added to provide wind protection, then wind resistance is improved, but the towel loses flexibility for standard use

Engineering Contradiction:
Improvewind resistanceVSAvoidflexibility for drying and lying
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The structure transitions from a flexible compressed state during normal towel use to a rigid expanded state when wind protection is needed. The hollow cylindrical pieces can be easily compressed into a compact form that flexes with the towel, then expanded by pulling the string mechanism to form a rigid barrier against wind

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rigid protective structure is divided into multiple hollow cylindrical pieces connected by strings. These segmented components can be individually compressed and stored within the towel fabric, then assembled into a rigid configuration when needed, allowing the structure to be both compact during storage and rigid during use

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If an internal structure is inserted to form a rigid barrier, then wind protection is achieved, but the device complexity increases

Engineering Contradiction:
Improvewind protectionVSAvoidinternal structure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The hollow cylindrical pieces serve multiple functions: they form the rigid protective barrier when expanded, and simultaneously compress into a compact form that can be stored within the towel fabric during normal use. The string mechanism both connects the cylindrical pieces and serves as the activation mechanism for expansion, eliminating the need for separate control systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The complex rigid structure is extracted from the towel as a separate insertable component rather than being permanently integrated into the fabric. The hollow cylindrical pieces and string mechanism can be removed from the towel and stored separately when not in use, simplifying the towel's construction and allowing the complex structure to be added only when wind protection is needed

Inventive Principle:
Principle #2Taking out (Extraction)
