Solution Overview

Problem

Conventional head supports for chairs lack the ability to provide adjustable head support in three dimensions, failing to accommodate varying user needs such as different body types, impairments, or specific comfort requirements.

Innovation Solution

An adjustable head support system featuring an articulating arm with multiple members that rotate about perpendicular axes, allowing for three-dimensional adjustment, including a swivel joint and height adjustment mechanism, to position a head support pad effectively for users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional head supports are used, then the structure is simple, but the adjustability in three dimensions is limited

Engineering Contradiction:

ImproveadjustabilityVSAvoidstructure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The head support device is divided into multiple independent members (first member, second member, third member) that can rotate relative to each other about perpendicular axes. Each member provides adjustment in a specific dimension, enabling three-dimensional positioning while maintaining modular simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from conventional single-axis or two-axis adjustment to three-dimensional adjustment by adding rotation about perpendicular axes. The first member rotates about a first axis, the second member about a second axis perpendicular to the first, and the third member about a third axis, providing comprehensive spatial adjustability

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If fixed head support position is used, then the structure is stable, but it cannot accommodate varying user needs

Engineering Contradiction:

ImprovecustomizabilityVSAvoidadjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The head support device employs dynamic adjustment capabilities through rotatable members that can be positioned at various angles. The swivel joint and rotation mechanisms allow users to dynamically adjust the head support to different positions and orientations, accommodating varying user needs while maintaining operational simplicity

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If multi-axis rotation mechanism is added, then three-dimensional adjustment is enabled, but the device complexity increases

Engineering Contradiction:

Improvethree-dimensional adjustmentVSAvoidarticulating arm mechanism

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each member in the articulating arm is designed to perform multiple functions: providing structural support, enabling rotation about a specific axis, and positioning the head support in three-dimensional space. The swivel joint serves as a universal connection point that facilitates rotation in multiple directions, reducing the need for separate mechanisms for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An adjustable head support includes an articulating arm that has a plurality of members, at least one of the members is attached to a consecutive member and configured to rotate about a first axis. At least another of the members is attached to a consecutive member and configured to rotate about a second axis, the first axis and the second axis being perpendicular. A head support assembly is pivotally coupled to the articulating arm.
