Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional fixed pegboard is used for rehabilitation training, then the device structure is simple, but the adaptability for different patient needs and training stages is insufficient

Engineering Contradiction:
Improveadaptability for different patient needsVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The pegboard is divided into multiple independent modules, each capable of being independently configured. This segmentation allows different regions to serve different training purposes while maintaining overall system flexibility, resolving the contradiction between adaptability and complexity by organizing functionality into manageable units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a static fixed pegboard to a dynamic reconfigurable system where modules can be moved, added, or removed based on patient progress and training requirements. This dynamic capability enables the board to adapt to different patient needs without requiring complete system replacement.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If a conventional pegboard without feedback mechanisms is used, then the device complexity is low, but the capability to provide real-time guidance and evaluate training progress is insufficient

Engineering Contradiction:
Improvetraining process informationVSAvoiddevice structure
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Sensors are integrated into the pegboard modules to detect peg insertion events and provide real-time feedback to the control system. This feedback mechanism captures training process information, enabling progress tracking and guidance while the control system processes data to provide meaningful feedback to patients.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Traditional mechanical feedback mechanisms are replaced with electronic sensors and digital processing systems. This substitution enables more precise detection and analysis of training actions, providing richer information about patient progress without significantly increasing physical device complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If a conventional pegboard with limited configuration options is used, then the manufacturing cost is low, but the ability to develop various patient senses and provide effective treatment is insufficient

Engineering Contradiction:
Improvetraining method varietyVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The modular design enables each module to serve multiple training functions depending on its configuration and positioning. A single module type can be used in different locations and arrangements to create various training scenarios, providing training method variety without requiring completely different components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables variation in training parameters such as module positions, spacing, and configurations without changing the fundamental module design. This approach allows customization of training difficulty and type by adjusting parameters rather than manufacturing entirely different components.

Inventive Principle:
Principle #35Parameter changes
