Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile terminals are used as information processing devices in grid computing, then portability and accessibility are improved, but communication stability and reliability deteriorate due to movement causing communication status fluctuations
Solution Approach 1:
The system dynamically switches transmission routes based on real-time communication status. When the terminal moves and communication status deteriorates, the system transitions from a direct transmission route to a relay route through other terminals, making the communication path adaptive to movement conditions and maintaining reliability while preserving portability
Solution Approach 2:
Other mobile terminals serve as intermediaries or relay nodes when direct communication between the base station and moving terminal is poor. The relay terminal forwards data packets, enabling communication to continue despite movement-induced signal degradation, thus maintaining reliability without sacrificing the mobile terminal's portability
2Speed
If data is transferred in advance to mobile terminals, then processing speed is improved, but data transfer time increases when communication status is poor
Solution Approach 1:
The system dynamically adjusts the data transfer strategy based on communication status. When communication is good, data is transferred in advance to enable fast processing. When communication deteriorates, the system switches to relay routing to reduce transfer time, thus optimizing both processing speed and minimizing data transfer time losses
Solution Approach 2:
Relay terminals are used as intermediaries to forward data when direct transfer is too slow. This multi-hop approach through other mobile terminals reduces the time required to transfer large data sets compared to waiting for slow direct communication, enabling processing to start sooner while managing transfer time constraints
3Productivity
If direct transmission route is used, then transmission efficiency is improved, but reliability deteriorates when communication status fluctuates due to terminal movement
Solution Approach 1:
The system dynamically switches between direct transmission and relay transmission based on communication status. When the terminal is stationary or moving slowly with good signal, direct transmission provides high efficiency. When the terminal moves causing status fluctuations, the system transitions to relay transmission to maintain reliability, thus balancing transmission efficiency and operation reliability adaptively
Solution Approach 2:
When direct transmission becomes unreliable due to movement-induced communication fluctuations, other mobile terminals act as intermediary relay nodes. This relay mechanism ensures data can still be transmitted reliably even when direct communication is unstable, maintaining operation reliability while accepting some efficiency trade-off necessary for mobile conditions
