Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal testing methods for smartphones supporting CDMA standards are time-consuming and inefficient due to manual operation, requiring testers to manually conduct signal emitting/receiving tests across multiple frequency bands.
Innovation Solution
A signal testing system comprising a handheld device, a testing apparatus, and a computer device connected via USB and communication interfaces, which automates the testing process by controlling the handheld device to access signal testing states and receive power values, utilizing an electric shielding box and plate antenna to prevent noise interference, and employing testing software to manage testing parameters and sequences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for signal testing, then testing flexibility is maintained, but testing efficiency is low and time consumption is high
Solution Approach 1:
The testing system performs automatic signal emission and reception testing without requiring manual intervention. The computer device automatically controls the handheld device to enter testing modes, transmits test signals, receives responses, and processes results, enabling the system to serve itself and eliminate manual operation time.
Solution Approach 2:
The patent replaces manual mechanical operation with automated electronic control. The computer device uses software to automatically manage the testing process, including controlling signal transmission, receiving responses, and analyzing results, substituting human manual operations with electronic automation.
2Productivity
If automated testing is implemented, then testing efficiency is improved, but system complexity increases
Solution Approach 1:
The computer device serves multiple functions: it controls the handheld device to enter testing modes, transmits test signals, receives responses, processes data, and displays results. This multi-functionality consolidates what would otherwise require multiple separate devices into a single integrated system.
Solution Approach 2:
The computer device acts as an intermediary between the handheld device and the testing apparatus. It manages the communication and control protocols, coordinating the signal transmission and reception processes, and handling the data processing, thereby simplifying the overall system architecture.
3Adaptability or versatility
If multiple CDMA frequency bands are tested, then global compatibility is verified, but testing time increases
Solution Approach 1:
The automated testing system continuously cycles through multiple CDMA frequency bands without interruption. The computer device automatically sequences the testing of different frequency bands (820-900 MHz, 1850-1990 MHz, 1710-1755 MHz, 2110-2155 MHz), maintaining continuous useful action to verify global compatibility efficiently.
