Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If WIFI mode is used for email transmission, then data transmission rate is improved, but standby duration is reduced and power consumption increases
Solution Approach 1:
The system dynamically switches between WIFI and WAN network interfaces based on real-time conditions. The mobile terminal evaluates network status, mail priority, and size to determine the optimal interface for each email transmission task, making the network selection dynamic rather than static.
Solution Approach 2:
The email transmission process is segmented into different strategies based on mail characteristics. High-priority or large emails are transmitted via WIFI when available, while low-priority or small emails use WAN interface, dividing the transmission workload across different network interfaces with distinct characteristics.
2Speed
If WIFI mode is used for email transmission, then data transmission rate is improved, but power consumption increases
Solution Approach 1:
Different network interfaces are assigned different qualities based on their characteristics. WIFI interface is used for high-speed transmission requirements, while WAN interface is used for power-saving scenarios. The system evaluates local conditions (network availability, mail characteristics) to select the appropriate interface quality.
Solution Approach 2:
The power consumption management is dynamic, adjusting the active network interface based on real-time conditions. The system monitors WIFI availability and switching status to dynamically control power consumption, switching to WAN interface when WIFI is unavailable or not needed.
3Duration of action of moving object
If WAN mode is used for email transmission, then standby duration is improved, but data transmission rate is reduced
Solution Approach 1:
The transmission task is segmented by priority and size. Critical or large emails that require fast transmission are sent via WIFI, while non-critical or small emails are sent via WAN interface, segmenting the workload to optimize both speed and power consumption.
Solution Approach 2:
The system changes transmission parameters (network interface selection) based on mail characteristics. By evaluating mail priority and size parameters, the system adjusts the transmission method to match the requirements, using high-speed WIFI for important emails and power-efficient WAN for less critical ones.
4Duration of action of moving object
If power-saving protocols are added to WIFI, then standby duration is extended, but device complexity increases
Solution Approach 1:
The complex power-saving protocol management is extracted from the WIFI implementation. Instead of modifying WIFI protocols to achieve power saving, the system uses a simpler approach: evaluating network conditions and mail characteristics to decide whether to use WIFI or WAN interface, avoiding complex protocol modifications.
Solution Approach 2:
The system uses a simple, lightweight decision-making mechanism based on predefined thresholds and real-time conditions rather than implementing complex long-term power-saving protocols. The strategy is simple and can be easily implemented without modifying core WIFI functionality.

AI summary
A method for pushing email in heterogeneous networks as well as a mobile terminal and a server are disclosed. The method comprise steps of: sending a mail notification including at least mail priority and mail size of the email from a mail-pushing server to a mobile terminal; determining, by the mobile terminal, a download strategy for the email based on at least one predefined threshold, said mail priority and said mail size; and downloading said email from the mail-pushing server based on the determined download strategy. With the above solutions, it is possible to seamlessly integrate the long standby duration in the WAN mode with free-of-charge and high speed in the LAN mode and thus give a full play to these advantages. Moreover, the mobile terminal can select automatically the most suitable mail access strategy based on network condition and mail size for the simultaneous realization of effective power saving and efficient transmission.
