Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the robot drives on uneven surfaces or encounters obstacles, then the robot can navigate complex environments, but shock is transferred to the loaded food causing potential overflow
Solution Approach 1:
The patent applies beforehand cushioning by providing a suspension system with shock absorbers and a stabilizer with damping plates before the robot encounters uneven surfaces or obstacles. The suspension system is pre-configured to absorb shocks and vibrations, protecting the loaded food from overflow when the robot navigates complex environments.
Solution Approach 2:
The patent uses the suspension system and stabilizer as intermediary elements between the robot's driving device and the loading member. These intermediaries absorb and dampen shocks transferred from the uneven terrain or obstacles, preventing direct transmission of harmful forces to the loaded food.
2Speed
If the robot accelerates or decelerates rapidly to respond to unexpected obstacles, then the robot can react quickly, but shock is transferred to the serving robot and loaded food
Solution Approach 1:
The suspension system with shock absorbers and the stabilizer with damping plates provide beforehand cushioning that absorbs shocks generated during rapid acceleration or deceleration. This allows the robot to respond quickly to obstacles while protecting the loaded food from overflow caused by shock.
Solution Approach 2:
The patent employs adjustable damping parameters in the stabilizer system, where the damping coefficient can be modified based on driving conditions. This allows optimization of shock absorption characteristics during different phases of motion, enabling quick response while minimizing shock transmission to the food.
3Object-affected harmful factors
If the robot uses a stable suspension system, then shock is reduced, but the robot's ability to adapt to different driving conditions is limited
Solution Approach 1:
The patent implements a dynamic stabilizer system where the damping coefficient can be adjusted based on driving conditions, food type, and robot state. This dynamic adjustment capability allows the suspension system to optimize shock absorption for different scenarios while maintaining adaptability to various driving conditions through active control.
Solution Approach 2:
The patent changes the damping parameter of the stabilizer based on detected driving conditions and food characteristics. By dynamically adjusting the damping coefficient, the system maintains effective shock reduction across different scenarios while adapting to varying driving conditions, resolving the contradiction between stability and adaptability.
