Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual propulsion is used in existing mobility systems, then the system structure remains simple, but user speed and comfort are limited
Solution Approach 1:
The patent combines a motor assembly with a skate platform to create a powered mobility system. The motor assembly includes a motor, bushing, and drive shaft that work together to rotate the drive wheel, enabling automated propulsion while maintaining a compact integrated structure.
Solution Approach 2:
The mobility system is divided into distinct functional modules: a powered skate with motor assembly for propulsion, a non-powered skate for balance and weight distribution, and a platform with straps for user support. This segmentation allows each component to perform its specific function while keeping the overall design manageable.
2Ease of operation
If automated propulsion is added to increase speed, then user comfort improves, but energy consumption increases
Solution Approach 1:
The motor assembly is designed to be activated by user input (such as leaning or pressing a trigger) and automatically propels the user without requiring continuous manual effort. The system self-regulates based on user input, providing comfortable automated propulsion while minimizing unnecessary energy consumption.
3Stability of the object's composition
If a single powered skate is used, then the system is simple, but user support and stability are insufficient
Solution Approach 1:
The system combines a powered skate and a non-powered skate into a unified mobility system. The powered skate provides propulsion and motorized movement, while the non-powered skate provides additional stability and weight distribution, creating a balanced and stable platform for the user.
Solution Approach 2:
The non-powered skate serves multiple functions: it provides structural support, distributes the user's weight, enhances stability during movement, and allows the user to perform tricks. This multi-functionality justifies its inclusion despite adding a component to the system.
4Productivity
If motor assembly components are added to automate propulsion, then productivity increases, but device complexity increases
Solution Approach 1:
The motor assembly integrates multiple components (motor, bushing, drive shaft) into a compact unified unit that directly powers the drive wheel. This merging reduces the number of separate parts needed while maintaining efficient automated propulsion capability.
