Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart terminals rely on WIFI hotspot for wireless network access, then network connectivity is achieved in areas with WIFI coverage, but network access becomes impossible in areas without WIFI hotspot availability
Solution Approach 1:
The casing apparatus integrates multiple communication modules including WIFI communication module and digital communication module (supporting LTE, UMTS, EVDO, TD-SCDMA, EDGE, GSM, CDMA) into a single device, enabling it to provide network access through multiple communication standards and networks, thus making the smart terminal adaptable to different network environments and eliminating dependency on a single communication system
Solution Approach 2:
The casing apparatus acts as an intermediary device between the smart terminal and the communication network. It receives WIFI signals from the tablet computer, processes them through the communication PCBA, and transmits them via antenna to connect to cellular networks, thereby mediating network access when direct WIFI hotspot availability is absent
2Reliability
If a casing apparatus integrates communication PCBA, antenna, and battery to enable wireless communication without WIFI hotspot, then network access availability is improved, but device structure and power management complexity increase
Solution Approach 1:
The patent combines the communication PCBA, antenna, and battery into an integrated casing apparatus that attaches to the smart terminal. This merging of multiple functional components into a single unified structure reduces the overall complexity compared to modifying the terminal itself, while ensuring reliable network access through integrated power and communication subsystems
Solution Approach 2:
The casing apparatus is designed as a nested structure where the communication PCBA is integrated within the casing body, the antenna is embedded in the casing, and the battery is housed within the same structure. This nested arrangement optimizes space utilization and simplifies the overall device architecture while maintaining all necessary functions for wireless communication
3Adaptability or versatility
If digital communication module supports multiple communication standards (LTE, UMTS, EVDO, TD-SCDMA, EDGE, GSM, CDMA), then network compatibility is improved, but module complexity and power consumption increase
Solution Approach 1:
The digital communication module is designed to dynamically select and activate only the necessary communication standards based on network availability and requirements. Instead of continuously operating all communication interfaces, the system adapts its power consumption by enabling only the required modules (LTE, UMTS, EVDO, TD-SCDMA, EDGE, GSM, or CDMA), thus reducing overall power usage while maintaining compatibility across multiple standards

AI summary
The present invention relates to a casing apparatus having the wireless communication function for a mobile terminal, comprising a casing apparatus body, and an antenna, a communication PCBA, and a battery supplying power to the communication PCBA that are arranged in the casing apparatus body; the communication PCBA is integrated with a digital communication module and a WIFI communication module, and the antenna and the battery are respectively connected to the communication PCBA. The casing apparatus according to the present invention transmits a WIFI signal from a tablet computer through the antenna to the WIFI communication module for processing, then transmits the processed signal to the digital communication module for modulation, and finally radiates the modulated signal through the antenna to access a wireless communication network. In this way, the WIFI signal from the tablet computer gets to access the network, thereby realizing the wireless access to the network even though there is no WIFI hotspot available.
