Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional balance training methods (manual pushing, platform shaking, treadmill speed control) are used, then balance training can be provided, but the training is limited to specific environments and cannot be applied in various situations

Engineering Contradiction:
Improvetraining applicability in various environmentsVSAvoideffectiveness of balance training
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The wearable device integrates multiple training modes (irregular torque application, regular torque application, and hybrid mode) into a single system that can be worn by users in various environments. The device includes actuators that can apply different torque patterns to the user's body, enabling balance training whether the user is walking, standing, or performing other activities, thus providing universal applicability across different situations and locations.

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

Solution Approach 2:

The device autonomously generates irregular pattern torques through its controller and actuator system without requiring external intervention. The controller automatically determines when and how much torque to apply based on sensor feedback from the user's motion state, enabling the system to self-regulate and provide adaptive training in various environments without needing constant external control or specialized training facilities.

Inventive Principle:
Principle #25Self-service

2Reliability

If irregular pattern torque is applied to simulate unexpected forces, then balance and reaction capabilities are enhanced, but the device complexity increases

Engineering Contradiction:
Improvebalance and reaction capability improvementVSAvoidcontroller and actuator system complexity
Core Design Contradiction:

Solution Approach 1:

The controller varies the torque parameters (magnitude, duration, frequency, and pattern) applied by the actuators to simulate different unexpected force scenarios. By changing these parameters dynamically based on the user's response and training progress, the system can provide diverse balance training stimuli without requiring complex mechanical structures, achieving enhanced training effectiveness through parameter variation rather than structural complexity.

Inventive Principle:
Principle #35Parameter changes
