Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual adjustment by technicians is used for configuring orthopedic apparatuses, then the apparatus can be adjusted, but the process is inefficient and requires time without real-time data feedback
Solution Approach 1:
The patent implements real-time feedback by capturing movement data during patient gait cycles and immediately displaying it to technicians through a user interface. This allows technicians to observe actual movement patterns and make data-driven adjustments to the orthopedic apparatus during the same session, eliminating the need for separate analysis phases and significantly improving configuration efficiency.
Solution Approach 2:
The system performs preliminary data collection and analysis by capturing movement data during the patient's natural gait cycle before final adjustments are made. The processing unit analyzes this data in advance to identify optimal adjustment parameters, allowing technicians to make precise adjustments based on pre-analyzed information rather than trial-and-error methods.
2Loss of information
If real-time data superposition is implemented during movement, then immediate data analysis and adjustment are enabled, but the device complexity increases
Solution Approach 1:
The patent employs a multi-functional integrated system where a single computing unit performs multiple tasks: capturing movement data from sensors, processing and analyzing the data, generating visual representations, and displaying information through a user interface. This consolidation of multiple functions into one system reduces overall device complexity compared to having separate dedicated components for each function.
Solution Approach 2:
The patent introduces a processing unit as an intermediary between the movement data capture system and the display system. This intermediary component consolidates multiple complex operations (data filtering, analysis, visualization generation) into a single manageable module, simplifying the overall system architecture while enabling real-time data processing and feedback.
3Manufacturing precision
If manual adjustment without real-time data feedback is used, then the process is simpler, but fitting accuracy and movement pattern optimization are suboptimal
Solution Approach 1:
The system captures real-time movement data during patient gait cycles and provides immediate feedback to technicians through visual displays showing actual movement patterns. This real-time feedback enables technicians to make precise adjustments to the orthopedic apparatus based on observed performance, significantly improving fitting accuracy compared to manual adjustment without data guidance.
Solution Approach 2:
The patent replaces traditional manual trial-and-error adjustment methods with an automated data-driven system. Sensors automatically capture movement data, computing units process and analyze this data, and results are displayed for technician decision-making. This substitution of mechanical/manual processes with automated electronic systems improves precision while managing complexity through software-based solutions.
