Solution Overview
Problem
Current roller skates are limited in traversing various terrains, particularly inclines, and lack safety mechanisms to address abnormal usage scenarios, making them unsuitable for long-distance travel and safe use.
Innovation Solution
A motorized roller skate system with two skateboards and a hand device, each equipped with sensors and signal devices that transmit detection signals to a control center, allowing for adaptive control of speed and safety features based on user input and terrain conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If roller skates are designed for recreational and sports activities, then they can provide good performance for these activities, but they are unsuitable for long distance travel and difficult terrains
Solution Approach 1:
The roller skate system automatically detects user status through sensors (foot presence, body tilt, hand gestures) and autonomously controls motor activation to provide power assistance for climbing inclines, eliminating the need for manual motor control while adapting to various terrains
Solution Approach 2:
The system continuously monitors user status through multiple sensors and adjusts motor power output in real-time based on detected conditions such as foot presence on skateboards, body tilt angle, and hand gestures, creating a closed-loop control system that adapts to terrain changes
2Ease of operation
If power assistance is added to roller skates to enable long distance travel, then traversing terrains becomes easier, but the learning curve becomes steeper and safety risks increase
Solution Approach 1:
The control system automatically interprets sensor data and activates motors without requiring user input or learning complex controls, with the system self-regulating based on detected user status and terrain conditions
Solution Approach 2:
The system divides control into independent functional modules: sensor detection modules (foot sensors, body tilt sensors, hand gesture sensors), processing modules, and motor control modules, allowing each component to function independently and simplifying the overall system architecture
3Ease of operation
If automatic motor control is implemented to reduce learning curve, then ease of operation improves, but safety mechanisms are insufficient for abnormal usage scenarios
Solution Approach 1:
The system preemptively activates safety features by detecting abnormal conditions (falls, abrupt acceleration, excessive speed) before they become dangerous, automatically activating alarms, emergency brakes, or reducing motor power to prevent accidents from occurring
Solution Approach 2:
The system continuously monitors operational parameters through sensors and adjusts behavior in real-time based on detected conditions, creating a closed-loop safety system that responds to abnormal usage scenarios and continuously adapts to ensure safe operation
