Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a gas sensor is installed in the cavity of a handheld device, then the device can perform gas sensing function, but installation space and circuit contacts must be reserved in advance, making it difficult to install if not reserved and requiring expertise for disassembly
Solution Approach 1:
The patent combines the gas sensing function with the SIM card, integrating the gas sensor, circuit board, and SIM card components into a single modular unit. This merging allows the gas sensing functionality to be added without requiring separate installation space or circuit contacts, as the SIM card slot already provides the necessary interface.
Solution Approach 2:
The SIM card is designed to serve multiple functions: traditional subscriber identification and gas sensing. By making the SIM card multi-functional, the patent enables gas sensing capability to be added to existing handheld devices without requiring additional dedicated components or modification of the device structure.
2Adaptability or versatility
If a gas sensor is installed in the cavity of the handheld device, then gas sensing function is achieved, but users lose the warranty by disassembling the device
Solution Approach 1:
By merging the gas sensor with the SIM card, the patent allows users to install gas sensing functionality by simply replacing or inserting a SIM card, which is a non-invasive operation that does not require disassembling the device. This preserves the device warranty while achieving gas sensing capability.
3Volume of moving object
If handheld devices become thinner, then portability is improved, but installation space and circuit contacts for gas sensor become unavailable
Solution Approach 1:
The patent merges the gas sensor with the SIM card, utilizing the existing SIM card slot and interface. This approach requires no additional installation space within the device body, allowing thin handheld devices to maintain gas sensing capability through the SIM card interface without increasing device thickness.
4Adaptability or versatility
If external gas sensor is equipped to wireless communication device, then gas sensing function is achieved, but device structure and hardware must be altered
Solution Approach 1:
The SIM card is designed to provide both traditional communication functions and gas sensing functionality. This multi-functional design eliminates the need for external gas sensors and hardware modifications, as the SIM card interface already exists in all wireless communication devices.

AI summary
The present invention provides a wireless communication device and a subscriber identity module card in a wireless communication device. The subscriber identity module card comprises a flat plate carrier, a subscriber identity module circuit and a gas sensing chip. The flat plate carrier comprises a first surface where the subscriber identity module circuit is disposed, a second surface where the gas sensing chip is disposed, a through hole, and an electrical contact portion passing through the through hole and extending to reach the first surface and the second surface. The electrical contact portion is electrically connected to the subscriber identity module circuit and the gas sensing chip. The gas sensing chip is disposed on a portion of the subscriber identity module card where not occupied by the subscriber identity module circuit. Thus, the wireless communication device provides gas sensing function without additionally equipping with an external gas sensing element.
