Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robots are designed with fixed preset services, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The robot system is divided into a base unit and interchangeable service modules. Each service module is an independent functional unit that can be detached and replaced. This segmentation allows the robot to maintain reliable operation of the proven base unit while adapting to different services through module replacement, resolving the contradiction between reliability and adaptability.
Solution Approach 2:
The base unit is designed with universal interfaces and standardized mounting mechanisms that can accommodate multiple types of service modules. This multi-functionality enables a single robot platform to perform diverse services (cleaning, delivery, inspection, etc.) by simply changing modules, thereby achieving both reliability through a proven platform and adaptability through modular versatility.
2Ease of operation
If service modules are made interchangeable and detachable, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The service modules are designed with self-aligning features and automatic connection mechanisms. When a module is attached to the base unit, electrical contacts, mechanical linkages, and communication interfaces automatically engage without requiring manual configuration or complex alignment procedures. This self-service capability simplifies the replacement operation while the standardized interfaces manage the underlying complexity.
Solution Approach 2:
The system employs standardized interface parameters (connection protocols, mechanical dimensions, electrical pinouts) that remain constant across different modules. This parameter standardization allows modules with different functions to be interchangeably mounted on the same base unit. The complexity is encapsulated within the module design parameters rather than affecting the overall system operation simplicity.
3Adaptability or versatility
If the head display unit is made rotatable, then adaptability is improved, but device complexity increases
Solution Approach 1:
The head display unit is equipped with a rotation mechanism that allows it to dynamically change its orientation angle. This dynamic capability enables the display to adapt to different viewing positions and operational contexts (facing forward, backward, or at angles). The rotation mechanism is integrated into the modular head unit, concentrating the complexity within a single replaceable component rather than the entire robot system.
Solution Approach 2:
The rotation mechanism is nested within the head display unit structure. The rotary actuator, gears, and mounting interfaces are all contained within the modular head assembly. This nesting approach allows the complex rotation functionality to be packaged within a compact form factor that fits within the overall robot dimensions, and the entire head unit can be replaced as a single module if needed.

AI summary
A robot includes a main body provided with a traveling unit, a body display unit disposed on an upper portion of a front side of the main body and elongated in a vertical direction, a head display unit rotatably connected to an upper portion of the body display unit, a rotary motor disposed inside the body display unit, a rotational shaft elongated in a vertical direction and rotated by the rotary motor to rotate the head display unit, and a speaker disposed inside the body display unit, spaced apart from the rotary motor, and overlapping the rotational shaft in a horizontal direction. The robot selectively receives various types of service modules to provide different services.
