Solution Overview

Problem

Users often fail to adjust office chairs ergonomically, leading to health issues like poor posture, musculoskeletal disorders, and increased healthcare costs due to lack of understanding on how to configure chairs for optimal ergonomic positions.

Innovation Solution

A programmable ergonomic chair system that wirelessly communicates with a mobile device application to calculate and adjust chair components based on user body measurements, using motorized actuators and ergonomic principles for optimal seating.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment mechanisms are provided for chair components, then the chair offers multiple adjustment options for ergonomic positioning, but users lack understanding of how to properly adjust the chair, resulting in poor ergonomic configuration

Engineering Contradiction:

Improveadjustment optionsVSAvoiduser understanding

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system uses sensors to automatically detect user body dimensions and automatically adjusts chair components to ergonomic positions, eliminating the need for users to manually understand and operate multiple adjustment mechanisms. The chair serves itself by making intelligent adjustments based on detected user characteristics.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment operations with an automated electronic control system that uses sensors, processors, and actuators to automatically position chair components, substituting complex mechanical user interactions with intelligent automated control.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If automated adjustment systems are implemented, then ergonomic optimization is achieved, but device complexity increases

Engineering Contradiction:

Improveergonomic optimizationVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

A single controller integrates multiple functions including sensing user body dimensions, processing ergonomic data, and controlling various chair components (seat height, backrest angle, armrest positions, lumbar support), consolidating complex automated adjustment capabilities into one unified control system.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system combines sensors, processors, memory devices, and actuators into an integrated automated adjustment system that works as a cohesive unit, merging detection, computation, and execution functions to achieve ergonomic optimization without proportionally increasing overall system complexity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method of controlling an adjustable chair comprising the steps of measuring the height of a person, entering the height of the person into a software application on a mobile device, taking a photograph of the person with a mobile device, analyzing the photograph to determine physical measurements of the person, storing the measurements in the mobile device; calculating optimum ergonomic adjustment of the chair based upon the stored measurements; and, transmitting signals to a controller in the chair to control actuators and adjust various components in the chair to achieve optimum ergonomic adjustment. The technology also includes the ergonomic task chair adjusted by the aforementioned method.
