Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to create a portable terminal that can reduce costs without increasing size, while maintaining the performance of wireless communication modules, which is difficult due to the integration of external wireless communication devices like LTE and 3G devices.
Innovation Solution
A portable terminal design with a slot on its side surface for a wireless communication module, featuring a module base with an antenna and a housing baffle for support, allowing the module to be inserted without increasing the terminal's size, and using a laser direct structuring antenna to minimize space, along with elastic connections for electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external wireless communication devices (LTE, 3G) are integrated into the portable terminal, then wireless communication functionality is improved, but the terminal size increases
Solution Approach 1:
The wireless communication module is separated from the main terminal body and placed in an external slot. This segmentation allows the terminal to have wireless communication capability through the removable module without permanently increasing the terminal's internal volume, resolving the contradiction between functionality and size.
Solution Approach 2:
The wireless communication module is designed to be inserted into a slot on the terminal body, creating a nested configuration where the module fits within the terminal's external dimensions. This allows the terminal to maintain its compact size while accommodating the additional wireless communication functionality when needed.
2Reliability
If wireless communication modules are integrated into the portable terminal, then communication performance is improved, but manufacturing cost increases
Solution Approach 1:
The wireless communication module is designed to be removable and replaceable, allowing users to upgrade or change modules based on needs. This dynamic configuration enables manufacturers to offer base models without expensive wireless modules, reducing initial manufacturing costs while allowing performance upgrades through user-selected modules.
Solution Approach 2:
The terminal slot is designed to accommodate different types of wireless communication modules (LTE, 3G, etc.), making the slot universal. This allows the terminal body to be manufactured once without integrated wireless functionality, then paired with different modules as needed, reducing overall manufacturing costs while maintaining communication performance options.
3Length of moving object
If the terminal thickness is reduced, then portability is improved, but space for wireless communication components is reduced
Solution Approach 1:
The wireless communication components are extracted from the terminal's internal structure and placed in an external removable module. This extraction allows the terminal body to be made thinner without sacrificing wireless communication capability, as the components reside in the external module rather than consuming internal thickness.

AI summary
A portable terminal and a wireless module are disclosed. The portable terminal comprises a terminal body and a wireless module. The terminal body comprises a front surface and a back surface opposite to each other, side surfaces connected to the front surface and the back surface, and a terminal circuit board disposed in a space defined by the front surface, the back surface and the side surfaces together; and a display region is disposed on the front surface. The terminal body is provided on one of the side surfaces thereof with a slot for the wireless module to be inserted therein. Disposed on a module circuit board of the wireless module is an SIM card that is electrically connected to the module circuit board. In this way, the present disclosure can selectively reduce the cost of the portable terminal and substantially not increase the size of the portable terminal.
