Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neck warmers lack the ability to effectively isolate smog and prevent the product from falling off the chin during physical activity, failing to provide adequate protection against external harmful environments such as haze.
Innovation Solution
A neck warmer with adjustable functionality, made of seamless high-stretch fabric, featuring ear accommodating holes for single or double-layer wear, elastic bands for secure fit, and ventilation fabric parts with KF filter paper for enhanced protection and filtration, allowing for customizable wear based on environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cylindrical buff structure is used to cover the neck and face, then ease of wearing is improved, but the product easily falls off during vigorous physical movement
Solution Approach 1:
The neck warmer is divided into multiple functional segments: a first warmer body for basic warmth, a second warmer body with KF filter paper for filtration, and elastic bands for securing. This segmentation allows each part to perform its specific function while working together to prevent the product from falling off during physical activity.
Solution Approach 2:
The invention combines different materials with complementary properties: high-stretch fabric for flexibility and fit, KF filter paper for particle filtration, and elastic bands for secure attachment. This composite structure maintains ease of wearing while significantly improving product stability during vigorous movement.
2Device complexity
If a simple cylindrical buff is used, then device complexity is reduced, but the ability to isolate smog and harmful environments is insufficient
Solution Approach 1:
The second warmer body with KF filter paper is nested within or alongside the first warmer body. This nesting arrangement allows the filtration function to be added without significantly increasing overall structural complexity, as the filter layer is integrated into the existing cylindrical buff structure.
Solution Approach 2:
KF filter paper is introduced as an intermediary layer between the user and the external environment. This mediator effectively isolates smog and harmful particles while maintaining the simple cylindrical structure, as the filtration function is achieved through material selection rather than complex mechanical design.
3Manufacturing precision
If the warmer body is made with fixed single-layer structure, then manufacturing precision is simplified, but adaptability to varying environmental conditions is reduced
Solution Approach 1:
The neck warmer employs a dynamic structure where the second warmer body can be adjusted relative to the first warmer body. Users can modify the layering configuration based on environmental conditions such as temperature and pollution levels, allowing the product to adapt to varying environments while maintaining standardized manufacturing processes for each component.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The neck warmer provides multi-layer protection and improved fit, ensuring effective heat retention, filtration, and respiratory protection, adaptable to varying environmental conditions through adjustable wear and replaceable filter paper.
Implementation Method 1
a first edge elastic band and a second edge elastic band, which are arranged at the end on both sides of the warmer fabric part and have stronger elastic elasticity than the warmer fabric part; a central elastic band which has stronger elastic elasticity in the middle part of the warmer fabric part than the warmer fabric part
Implementation Method 2
a first ventilation fabric part and a second ventilation fabric part are respectively formed between the central elastic band, the first edge elastic band and the second edge elastic band, the first ventilation fabric part and the second ventilation fabric part have a lower density than the warmer fabric part, and are just at the positions corresponding to the respiratory organs of a wearer

AI summary
A neck warmer with adjustable function comprises a warmer body with first opening and second opening; and a first ear accommodating hole and a second ear accommodating hole, which can be hung on the ear so that the warmer body adopts single-layer waring form, or fold the warmer body in half, hang the first and second ear accommodating holes on the ears, so that the warmer body adopts a double-layer wearing form. The warmer body is made of seamless and comfortable high-stretch fabric. A certain number of ear accommodating holes are formed on both sides and middle of the warmer body. In order to cope with the external environment including air temperature and severe haze weather, the warmer body adopts a design structure that can be worn in a single layer or folded in half to form a double-layer structure, so as to achieve the purpose of multi-layer protection.
