Solution Overview

Problem

Existing hairbands and hair ties are separate items, leading to inconvenience in carrying and increased loss, and existing combined designs suffer from material discomfort, environmental issues, and high production costs.

Innovation Solution

A hairband with an elastic loop band made of elastic fabric strip, featuring a joint portion that allows one end to function as a hairband and the other as a hair tie, reducing production complexity and cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a general inelastic fabric is used as the hairband with elastic bands sewn on both sides, then the product can function as both a hairband and hair tie, but the inelastic fabric is not elastic and inconvenient to use, and multiple sizes are needed for different head circumferences, increasing production complexity and cost

Engineering Contradiction:

Improvedual function as hairband and hair tieVSAvoidconvenience of use

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies universality by designing a single elastic loop band that can serve multiple functions: it can be worn as a hairband around the head and also used to tie hair into ponytails or buns. The elastic loop band integrates the functions of both the hairband and hair tie into one universal accessory, eliminating the need for separate items and multiple sizes.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a plastic headband is used with an elastic band set between the two ends, then the product can be used as a headband or hair bundle, but the plastic material is hard in texture and causes discomfort to the head and cheeks, and has environmental protection issues

Engineering Contradiction:

Improvedual function as headband and hair bundleVSAvoiddiscomfort and environmental harm

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies parameter changes by switching from rigid plastic material to soft elastic fabric material. This material parameter change transforms the product from hard and uncomfortable to soft and comfortable, while also improving environmental compatibility. The elastic fabric provides both comfort against the skin and flexibility for multiple uses.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If separate hairband and hair tie items are used, then each item can perform its specific function, but they cause trouble in carrying and are often lost, affecting their use

Engineering Contradiction:

Improvefunctional performanceVSAvoidconvenience of carrying

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies merging by combining the hairband and hair tie into a single integrated elastic loop band. This unified design eliminates the need to carry separate items, reducing the risk of loss while maintaining both functions. The elastic loop band can be configured in different ways to achieve both headband and hair-tying functions.

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If multiple elastic fabric strips of the same or different colors and patterns are sewn together to form the elastic loop band, then the product offers more design options, but the production complexity increases

Engineering Contradiction:

Improvedesign varietyVSAvoidproduction complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies segmentation by allowing the elastic loop band to be constructed from multiple separate elastic fabric strips that are sewn together. This segmentation approach enables different colors and patterns to be combined creatively while maintaining a relatively simple production process. Each strip can be prepared independently and then joined to form the complete loop band.

Inventive Principle:

Principle #1Segmentation

AI summary

A hairband with hair-binding function that uses an elastic loop band made of an elastic fabric strip, and forms a joint portion in the middle of the elastic loop band, so that a corresponding elastic band is formed on each of both sides of the joint portion, so that one elastic band can be used as a hairband, and the other elastic band can be used to tie the hair to form a ponytail or bun.
