Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile device operates continuously to complete maintenance tasks, then productivity is improved, but the battery charge depletes leading to device downtime
Solution Approach 1:
The control unit performs preliminary estimation of the charge level and predicts whether the battery will be sufficient to complete the working cycle before the cycle begins. This allows proactive management of battery resources, enabling the device to plan its operations to avoid depletion and downtime.
Solution Approach 2:
The system continuously monitors the actual charge level during operation and compares it with the estimated level. This feedback mechanism allows the control unit to adjust operations in real-time, ensuring the device can complete its working cycle without unexpected battery depletion and subsequent downtime.
2Reliability
If the mobile device returns to docking station for recharging, then battery charge is restored, but operating time is lost and productivity decreases
Solution Approach 1:
The control unit estimates the charge level in advance and determines whether it will be sufficient to complete the current working cycle. This preliminary assessment allows the device to commit to completing its current tasks before returning for recharging, maximizing productive operating time.
Solution Approach 2:
The system dynamically adjusts operational parameters such as speed and workload based on the estimated charge level. When charge is limited, the device optimizes its performance to complete essential tasks with available energy, thereby extending operating time before recharging is necessary.
3Productivity
If the mobile device operates with higher speed and workload, then productivity increases, but energy consumption increases leading to faster battery depletion
Solution Approach 1:
The control unit dynamically adjusts operational parameters including speed and workload based on real-time or estimated charge level. This dynamic adaptation allows the device to optimize the balance between productivity and energy consumption, maintaining high performance when charge is sufficient and adjusting downward when charge is limited.
Solution Approach 2:
The system changes operational parameters such as movement speed and task intensity according to the estimated charge level. By modulating these parameters, the device can extend its operating duration without sacrificing too much productivity, or complete tasks faster when energy is abundant.
