Solution Overview

Problem

Existing neck supports fail to individually adapt to the unique anatomical properties and head shapes of users, leading to discomfort and muscle tension during long overhead work.

Innovation Solution

A neck support system featuring elastically bendable legs connected by cross struts, adjustable joints, and a textile cover, allowing for flexible adaptation to the user's head shape and neck length, with a body connection that can be secured to the upper body via a holding device and rail system for precise adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed or height-adjustable curved structures are used to support the head, then the neck support provides basic structural support, but it cannot adapt to individual anatomical features and head shapes

Engineering Contradiction:
Improveadaptation to individual anatomyVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by replacing fixed curved structures with elastically bendable legs that can dynamically adapt to different head shapes and anatomical features. The legs are made of elastomeric material that allows them to bend and conform to the user's head contours, providing customized support without requiring complex adjustment mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by using elastomeric legs whose physical properties (flexibility, elasticity) allow them to change shape in response to applied forces. The legs can be bent to different degrees and angles, changing their geometric parameters to match individual anatomical variations, thus achieving adaptability through material property utilization rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the head support is made rigid to provide stable support, then structural stability is improved, but comfort and adaptation to head shape are reduced

Engineering Contradiction:
ImprovecomfortVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies flexible shells and thin films by using elastically bendable legs made of elastomeric material instead of rigid structures. These flexible legs can conform to the contours of the user's head, providing comfort through close contact and customization, while still maintaining structural stability through the elastic properties of the material and the geometry of the leg assembly with cross struts.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent utilizes composite materials by combining elastomeric material with a textile cover. The elastomeric legs provide the necessary flexibility and elastic support, while the textile cover adds comfort, friction reduction, and aesthetic qualities. This composite construction achieves both comfort and structural integrity.

Inventive Principle:
Principle #40Composite materials

3Force

If the neck support is made lightweight for comfort, then ease of wearing is improved, but the ability to provide sufficient support force is reduced

Engineering Contradiction:
Improvesupport forceVSAvoiddevice weight
Core Design Contradiction:
ForceVSWeight of moving object

Solution Approach 1:

The patent applies mechanics substitution by replacing heavy rigid mechanical structures with elastic deformable elements. The elastomeric legs utilize elastic deformation and spring-back forces to provide support, eliminating the need for heavy mechanical actuators or rigid support structures. The support force is generated through the elastic properties of the material rather than through mechanical force application.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
