Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless communication protocols are used to minimize transmission time and power consumption, then power efficiency is improved, but data throughput and latency are worsened due to lower bitrates and frequent triggering
Solution Approach 1:
The communication channel is divided into discrete time slots, with each device allocated specific slots for transmission and reception. This segmentation allows devices to remain in low-power states between slots while maintaining structured communication, resolving the contradiction between power saving and data throughput by organizing traffic efficiently in time-domain segments.
Solution Approach 2:
The system employs periodic communication slots where devices alternately transmit and receive data at predetermined intervals. This periodic structure enables devices to enter sleep modes between active slots, reducing overall power consumption while maintaining consistent data throughput through regular communication cycles.
2Productivity
If wired communication protocols are used to provide high throughput and constant transmission, then data throughput is improved, but power consumption increases due to continuous reception and transmission
Solution Approach 1:
Instead of continuous transmission like wired protocols, the system uses periodic time-slotted communication where devices activate only during their assigned slots. This maintains high throughput during active periods while dramatically reducing average power consumption through structured idle periods between transmissions.
Solution Approach 2:
The communication system dynamically switches between active transmission states and low-power idle states based on predetermined schedules. This dynamic operation allows the system to achieve wired-like throughput during active slots while consuming far less power overall, adapting the transmission pattern to actual data needs rather than maintaining constant connectivity.
3Stability of the object's composition
If communication slots are assigned to synchronize multiple devices in a TDMA network, then device coordination is improved, but system complexity increases due to schedule management and timing alignment
Solution Approach 1:
Communication slots and timing schedules are predetermined and assigned to devices before communication begins. This preliminary configuration establishes fixed transmission and reception windows for each device, simplifying real-time operation while maintaining strong synchronization. Devices simply follow their pre-assigned schedule rather than dynamically negotiating timing, reducing operational complexity.
Solution Approach 2:
Each device independently follows its assigned time slot schedule without requiring continuous central coordination. The predetermined slot allocation allows devices to self-synchronize by activating only during their designated windows, reducing the complexity of centralized schedule management while maintaining network-wide synchronization.
4Measurement precision
If receivers are enabled constantly to time the start of reception, then reception accuracy is improved, but power consumption increases significantly
Solution Approach 1:
Receivers are enabled periodically only during predetermined reception slots rather than constantly. Each device knows in advance when it should be receiving, allowing it to enter low-power states between slots. This periodic activation maintains timing accuracy for receptions while dramatically reducing power consumption compared to constant receiver operation.
Solution Approach 2:
Reception timing schedules are predetermined and communicated to devices before operation begins. Each device knows exactly when to activate its receiver for upcoming slots, allowing it to sleep between activations without missing timing information. This preliminary scheduling maintains reception accuracy while enabling power-saving idle periods.
