Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot is designed with a seat and support structures for human riding, then the robot's versatility and service capability are improved, but the device complexity and structural burden increase
Solution Approach 1:
The robot integrates multiple functions including human transportation, cargo carrying, and service provision through a unified platform. The seat structure serves both as a human support element and as part of the overall vehicle body, while the foot supporter and arm supporters provide both structural support and functional interfaces for human interaction, eliminating the need for separate dedicated components for each function.
Solution Approach 2:
The support structure is divided into distinct modular components: a seat for human sitting, a foot supporter for foot placement, and arm supporters for arm rest. Each component is independently configured and can be adjusted or removed as needed, reducing overall structural complexity while maintaining versatility.
2Ease of operation
If the foot supporter is made movable through a moving mechanism, then user comfort and adaptability are improved, but the device complexity increases
Solution Approach 1:
The foot supporter is designed with movable capability through a simple moving mechanism that allows it to adjust position along the longitudinal direction. This dynamic adjustment enables the foot supporter to adapt to different user leg lengths and seating positions, improving comfort without requiring complex multi-degree-of-freedom mechanisms.
3Ease of operation
If the seat is elevated using an elevation mechanism, then user comfort and accessibility are improved, but the device complexity and energy consumption increase
Solution Approach 1:
The seat is configured to be elevatable along the vertical direction through an elevation mechanism, allowing it to adjust height to accommodate different user sizes and improve accessibility. The mechanism enables smooth vertical movement while maintaining stability, and can be controlled to move only when necessary, minimizing energy consumption.
4Shape
If the robot maintains a compact design, then the aesthetic appearance and space efficiency are improved, but the accommodation space for mechanisms and components is reduced
Solution Approach 1:
The support structures are integrated into the robot's body in a nested arrangement where the seat, foot supporter, and arm supporters are positioned to utilize the same vertical and lateral space. The foot supporter extends forward from beneath the seat area, while arm supporters are positioned laterally, allowing all components to coexist within a compact footprint without requiring separate dedicated volumes.
