Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current test techniques for wireless communication apparatuses are inefficient as they can only test one side of the circuit board at a time, leading to increased manufacturing costs due to low test efficiency.
Innovation Solution
A measuring system with first and second probes arranged on opposite sides of a double-sided circuit board, connected to a control module, allowing simultaneous measurement of test points on both sides, including power supply, ground, and wireless signal points, and optionally featuring a shielding enclosure to reduce electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single-sided test technique is used, then test setup is simple, but test efficiency is low
Solution Approach 1:
The patent transitions from single-sided testing to double-sided testing by adding probes on both sides of the circuit board. This dimensional change allows simultaneous measurement of multiple test points, effectively doubling the testing capacity and resolving the contradiction between test efficiency and system complexity.
Solution Approach 2:
The patent combines multiple test operations into a single simultaneous testing process. By coordinating first probes and second probes to measure multiple test points at the same time, the system merges sequential testing into parallel operation, significantly improving productivity.
2Loss of time
If multiple test points are measured sequentially, then measurement accuracy is maintained, but test time increases
Solution Approach 1:
The patent enables continuous simultaneous measurement of multiple test points without interruption. The control module coordinates all probes to operate continuously and concurrently, eliminating the idle time between sequential measurements while maintaining signal integrity through proper synchronization.
Solution Approach 2:
The control module pre-configures the testing sequence and coordinates probe activation before actual measurement begins. This preliminary setup ensures that all probes are ready to measure simultaneously, reducing setup time and ensuring measurement accuracy is maintained from the start of the testing process.
3Productivity
If access to test machine is required multiple times, then comprehensive testing is achieved, but manufacturing cost increases
Solution Approach 1:
The testing system is designed with universal capability to test multiple different types of signals simultaneously using the same hardware platform. The control module can configure the probes to measure various signal types without requiring separate specialized equipment, reducing manufacturing costs while maintaining comprehensive testing capability.
