Automated Workstation Fixture Adjustment for Operator Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current work stations for handling large workpieces, such as frame members or floor beams, require manual adjustments to accommodate different human operators, which are often limited and do not account for individual physiological differences, leading to potential operator fatigue.
Innovation Solution
An automated work station with a computer-implemented method that adjusts the height and orientation of a workpiece holding fixture based on operator-specific anatomical and physiological data, using actuators and a computer system to optimize the ergonomic position for each operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustments are used to accommodate different operators, then the workstation can be adapted to different physiological characteristics, but the adjustment process is time-consuming and requires operator intervention
Solution Approach 1:
The system stores anatomical data for multiple operators in advance in a database. When an operator arrives, their pre-stored anatomical data is automatically retrieved and used to configure the workstation, eliminating the need for manual measurements and adjustments during the work setup phase.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated computer-controlled system. The computer processor automatically calculates and commands the actuators to position the workpiece holding fixture based on retrieved anatomical data, substituting operator intervention with automated digital control.
2Ease of operation
If manual adjustments are made by operators, then the workstation can be configured for different operators, but operator fatigue occurs due to repetitive manual positioning
Solution Approach 1:
The workstation performs self-adjustment automatically based on the operator's identity. The system retrieves the operator's anatomical data, calculates optimal positioning parameters, and executes adjustments without requiring the operator to manually reposition components, making the system serve itself rather than requiring operator labor for configuration.
Solution Approach 2:
The patent replaces manual mechanical adjustment operations with automated computer-controlled actuation. The computer processor sends commands to actuators that automatically position the workpiece holding fixture, eliminating the need for operators to perform repetitive manual positioning tasks that cause fatigue.
3Adaptability or versatility
If the workpiece holding fixture is fixed in position, then the structure is simple and stable, but it cannot accommodate different operators' physiological characteristics
Solution Approach 1:
The patent transforms the fixed workpiece holding fixture into a dynamic, adjustable system. The fixture is equipped with actuators that enable it to change position and orientation automatically based on the operator's anatomical data, allowing a single fixture design to serve multiple operators with different physiological characteristics.
Solution Approach 2:
The automated workpiece holding fixture is designed to perform multiple functions: it can accommodate workpieces of different sizes, adjust to different operators' anatomical characteristics, and reposition itself automatically. This universal design allows one fixture to replace what would traditionally require multiple fixed fixtures for different operators.
4Ease of operation
If automated adjustment systems are implemented, then operator fatigue is reduced and ergonomics are improved, but the system complexity and initial cost increase
Solution Approach 1:
The patent replaces complex manual adjustment procedures with a computer-controlled automated system. The computer processor retrieves anatomical data, calculates optimal positioning, and commands actuators to adjust the fixture, substituting human judgment and manual operation with automated digital control and reducing long-term operational complexity.
Solution Approach 2:
The system performs self-configuration automatically based on operator identification and stored anatomical data. The computer processor independently calculates positioning parameters and executes adjustments without requiring external intervention or complex operator procedures, making the automation system self-sufficient and reducing operational complexity.
Data Source
AI summary
A method, automated workstation, and computer system for automatically adjusting a workpiece to suit a particular operator is provided. An operator can be identified by scanning an identification badge, using facial recognition, or voice recognition. A physiological profile for the identified operator is then retrieved. A work station holding a workpiece is then automatically adjusted to set the workpiece at a height and/or orientation that is ergonomically beneficial for the operator.
