Innovation Solution
A communication device with a control module and a built-in communication module, featuring a connecting port that allows users to selectively activate either the external or built-in communication module, or both, through a user interface, enabling flexible mode switching without the need for redundant hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-mode mobile phone installs two different system chips and related components on a circuit board to support both GSM and PHS systems, then the communication versatility is improved, but the physical size of the circuit board cannot be reduced and the manufacturing cost increases
Solution Approach 1:
The communication device uses a single communication module that can operate in multiple communication modes (GSM and PHS) by switching between different communication protocols. The control module enables this single module to perform the functions of what would traditionally require two separate modules, thereby reducing circuit board size while maintaining dual-mode capability.
Solution Approach 2:
The communication module is designed with dynamic switching capability, allowing it to adapt between GSM and PHS communication modes based on external signals from the control module. This dynamic reconfiguration enables one module to replace two static modules, reducing the overall hardware footprint.
2Adaptability or versatility
If dual-mode mobile phone installs two different system chips and related components on a circuit board to support both GSM and PHS systems, then the communication versatility is improved, but the manufacturing cost increases
Solution Approach 1:
By designing a single communication module capable of operating in both GSM and PHS modes under control of the control module, the device reduces the number of components that need to be manufactured and assembled. This universal module approach lowers manufacturing costs while maintaining the ability to support multiple communication systems.
Solution Approach 2:
The invention merges the functionality of two separate communication modules (GSM and PHS) into a single integrated communication module. This consolidation reduces component count, simplifies the bill of materials, and decreases manufacturing complexity, thereby reducing overall manufacturing cost.
3Adaptability or versatility
If dual-mode mobile phone installs two different system chips and related components on a circuit board to support both GSM and PHS systems, then the communication versatility is improved, but the lightweight and compact design cannot be achieved
Solution Approach 1:
The control module enables a single communication module to perform the functions of two separate modules by dynamically switching between GSM and PHS protocols. This eliminates the need for redundant hardware, reducing the overall weight of the device while maintaining the capability to support both communication systems.
