Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal main boards are inefficient as they require separate designs and increased costs for manufacturing, as they need to accommodate both network locking and non-network locking functions, leading to hardware resource wastage and higher expenses.
Innovation Solution
A main board design with a configurable layout that includes pads for connecting a user identification unit, central processing unit, and encryption chip, allowing for network/card locking implementation by connecting the encryption chip only when required, thereby reducing unnecessary hardware and design costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the encryption chip is connected between the central processing unit and the user identification unit to implement network locking, then the network locking function is achieved, but hardware resources are wasted and costs are increased when network locking is not required
Solution Approach 1:
The patent implements a dynamic main board design where the connection between the central processing unit and user identification unit can be configured based on requirements. The main board includes a first pad connected to the user identification unit, a second pad connected to the central processing unit, and a third pad that can connect the encryption chip to both pads when network locking is needed. This dynamic configurability allows the system to adapt its hardware structure according to whether network locking functionality is required, thereby avoiding unnecessary hardware resource waste while maintaining the capability to implement network locking when needed.
2Device complexity
If the main board is redesigned to connect the central processing unit and user identification unit directly for terminals without network locking, then hardware resources are optimized, but design and testing expenses are increased
Solution Approach 1:
The patent creates a universal main board design that can serve both network-locked and non-network-locked terminal requirements through a single standardized structure. The main board includes configurable pads (first pad for user identification unit, second pad for central processing unit, and third pad for encryption chip connection) that allow the same main board design to be used across different terminal types. This multi-functionality eliminates the need for separate main board designs and testing processes for different terminal configurations, significantly reducing design and manufacturing expenses while optimizing hardware resource utilization.
3Adaptability or versatility
If the encryption chip is left unused in terminals without network locking requirement, then network locking capability is available for future use, but production costs are increased
