Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the complexity of walking routes and cognitive tasks is increased to improve physical and cognitive performance, then the effectiveness of the training system is improved, but the difficulty of operation and user adherence may deteriorate
Solution Approach 1:
The system dynamically adjusts the complexity of walking routes and cognitive tasks based on real-time sensing of user load, walking speed, and cognitive performance. The processor continuously monitors these parameters and modifies task difficulty to maintain optimal challenge without overwhelming the user, thereby improving adherence while enhancing performance.
Solution Approach 2:
The system incorporates multiple sensors to detect user load, walking speed, and cognitive task performance, feeding this information back to the processor. The processor uses this feedback to adjust the complexity of subsequent tasks, creating a closed-loop system that adapts to user capability and maintains engagement without excessive difficulty.
2Productivity
If the walking route complexity is adjusted to set physical task intensity, then physical performance improvement is enhanced, but the system complexity increases
Solution Approach 1:
The walking support robot integrates multiple functions including physical walking support, cognitive task presentation, performance monitoring, and adaptive task adjustment within a single system. The processor coordinates all these functions, managing route complexity, cognitive task difficulty, and real-time parameter adjustment through a unified control architecture.
3Productivity
If cognitive tasks are presented during walking to prevent dementia, then cognitive attentiveness is improved, but the overall task complexity and difficulty of operation increase
Solution Approach 1:
The system merges physical walking tasks with cognitive tasks into a unified training program. The processor coordinates both types of tasks simultaneously, adjusting their relative intensities based on user performance. This integration allows cognitive training to occur naturally during walking without requiring separate sessions or overly complex independent task management.

AI summary
A walking support robot is presented by the present disclosure. The walking support robot moves in accordance with a handle load while guiding a user to walk along a walking route. The walking support robot includes a body, a handle on the body, a sensor that senses a load applied to the handle, and a moving device that moves the walking support robot by controlling rotation of a rotating member in accordance with the load. Guide information is generated for guiding the user to walk along the walking route. Presented information is presented for guiding the user based on the guide information. A physical task is set by adjusting complexity of the walking route. A degree to which the user follows the walking route is calculated, and the physical task is adjusted based on the degree.
