Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ergonomic workstation designs fail to provide objective, individualized measurements for optimal spinal posture, leading to back pain, leg pain, neck pain, and other disorders due to reliance on anthropometric landmark data and subjective adjustments.
Innovation Solution
The use of mobile computing devices with accelerometers to measure hip-spine position and leg strength, providing objective metrics through tools like HIPINDIX and HIPTORQUE, which analyze chair height and workstation configuration to align the lumbar spine with gravity, reducing stress and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If anthropometric landmark data and subjective adjustments are used to design ergonomic workstations, then the design process is simple and accessible, but the measurement precision and objective evaluation of spinal posture are insufficient
Solution Approach 1:
The patent replaces complex mechanical measurement systems with mobile computing devices equipped with accelerometers, gyroscopes, and cameras. These sensors objectively measure spinal posture parameters without requiring complex mechanical apparatus, thereby improving measurement precision while avoiding device complexity
Solution Approach 2:
The patent uses photographic capture and image processing to create a digital model of the user's posture. The camera captures visual information of the user's body position, and software algorithms process these images to extract precise spinal alignment data, replacing the need for complex physical measurement tools
2Adaptability or versatility
If adjustable chairs and desks are used to accommodate individual users, then adaptability to different body types is improved, but the ease of operation increases due to multiple adjustment requirements
Solution Approach 1:
The patent implements automated feedback systems where the mobile device captures real-time posture data, processes it through algorithms, and provides immediate feedback to the user about optimal chair and desk heights. This automated feedback loop eliminates the need for users to manually trial-and-error adjust multiple components, maintaining adaptability while simplifying operation
Solution Approach 2:
The system enables users to independently determine their optimal workstation configuration through automated posture analysis. The mobile application guides users through simple positioning tasks and automatically calculates the ergonomic parameters, allowing users to self-adjust their workstations without requiring expert intervention or complex adjustment procedures
3Loss of time
If trial and error methods are used to adjust workstation components, then the device complexity remains low, but the loss of time for achieving optimal ergonomic configuration increases
Solution Approach 1:
The patent performs preliminary ergonomic assessment by capturing user posture data immediately upon setup using the mobile device. The system pre-calculates optimal workstation parameters based on the captured anthropometric data, eliminating the need for time-consuming trial and error adjustments later. This preliminary measurement and calculation phase significantly reduces setup time
Solution Approach 2:
The patent replaces manual trial-and-error adjustment processes with automated sensor-based measurement and calculation systems. The mobile device's accelerometers, gyroscopes, and cameras rapidly capture posture data and compute optimal configurations, reducing setup time from potentially hours of adjustment to minutes of automated assessment

AI summary
Aspects of this invention include new measures of hip-torso posture and strength of the legs. These new measures are made using new tools. Measurement of hip-torso posture can be made using simple tools. One such tool can be applied to the hips, and indicates relative angle of the spine. Photographic tools can be used to analyze posture relative to vertical references. Measurement of leg strength can be made using a device incorporating accelerometers and computer implemented instructions to quantify forward/backward, left/right, or rotational acceleration when the legs are challenged. Other aspects include devices with computer implemented instructions to quantify leg strength. Using the new devices and methods, one can objectively determine postures that are ergonomically appropriate for persons sitting and working at workstations.
