Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual refilling of consumables is used in conventional robotic devices, then the device structure remains simple, but the operation becomes laborious and inefficient
Solution Approach 1:
The robotic device automatically replenishes its own consumables by docking with a base station that transfers water, cleaning solution, or other supplies without human intervention. The system uses automated mechanical connections and pumping mechanisms to transfer consumables from the base to the robot's reservoirs.
Solution Approach 2:
The base station pre-stores consumables in large reservoirs before the robot needs them. When the robot docks, the consumables are automatically transferred in advance, ensuring the robot is always ready for operation without requiring manual refilling during its working cycle.
2Loss of substance
If primitive navigation systems are used in conventional robotic devices, then the device complexity is reduced, but resource wastage increases due to inefficient path planning
Solution Approach 1:
The navigation system uses sensors to continuously detect obstacles, walls, and environmental features, feeding this information back to the control system. The robot adjusts its path in real-time based on this feedback, avoiding redundant movements and ensuring efficient coverage of the operating environment while minimizing consumable usage.
Solution Approach 2:
The sensor system serves multiple functions: obstacle detection, wall following, position localization, and environmental mapping. This multi-functional approach allows sophisticated navigation and resource efficiency without proportionally increasing system complexity, as the same sensors support multiple operational modes.
3Adaptability or versatility
If application-specific robotic devices are used, then the device is optimized for a single function, but the ability to switch between tasks is limited
Solution Approach 1:
The robotic device uses detachable functional cartridges that can be easily removed and replaced. Each cartridge is designed for a specific function (mopping, vacuuming, sweeping), and the robot's body contains universal mounting mechanisms and control systems that automatically recognize and adapt to different cartridge types, enabling task switching without complex reconfiguration.
Solution Approach 2:
The robot's body incorporates universal components including a standard mounting interface, common drive mechanism, and centralized control system that can operate with different functional cartridges. This universal design allows the same base unit to perform multiple functions by simply changing the attached cartridge, significantly enhancing adaptability while keeping overall system complexity manageable.
4Reliability
If conventional docking stations are used, then the charging function is provided, but reliable mechanical and electrical mating is difficult to achieve
Solution Approach 1:
The docking system uses sensor-based alignment and guidance to replace complex mechanical mating structures. Optical or proximity sensors detect the base station's position and guide the robot into proper alignment, while flexible electrical contacts and tolerant mechanical interfaces ensure reliable connection without requiring precision mechanical fit-up.
Solution Approach 2:
The docking mechanism incorporates dynamic adjustment capabilities where the robot and/or base can automatically adjust their positions and orientations during the docking process. This dynamic adaptation ensures reliable mechanical and electrical connections even with variations in positioning, reducing the need for overly complex fixed mechanical structures.
