Modular Anechoic Chamber for Wireless Signal Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal throughput testing for wireless devices requires multiple anechoic chambers and equipment to simulate various environments, increasing costs, manpower, and test time, as well as occupying significant configuration space.
Innovation Solution
A modular signal test system with a first chamber and a removable second chamber, where the first chamber has wave-absorbing walls and the second chamber has wave-reflecting walls, allowing for simulation of different environments by moving the second chamber in and out of the first, with a testing computer and antenna setup for wireless testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple anechoic chambers are used to simulate various test environments, then test environment diversity is improved, but cost, manpower, and configuration space increase
Solution Approach 1:
The test system is divided into two separate chambers: a first anechoic chamber for absorbing electromagnetic waves and a second chamber that can be configured with either wave-absorbing or wave-reflecting inner walls. This segmentation allows each chamber to have specialized functionality while working together to simulate different test environments, eliminating the need for multiple complete anechoic chambers.
Solution Approach 2:
The second chamber is designed with dual functionality: it can be configured with wave-absorbing inner walls to simulate open space environments or with wave-reflecting inner walls to simulate crowded urban areas. This multi-functionality allows a single chamber structure to replace what would traditionally require multiple specialized chambers, reducing configuration space requirements.
2Adaptability or versatility
If multiple anechoic chambers are used to simulate various test environments, then test environment diversity is improved, but cost and equipment requirements increase
Solution Approach 1:
The system merges the functionality of multiple test environments into a single integrated setup. The first anechoic chamber combined with the configurable second chamber creates a unified system that can simulate both open space and crowded urban area environments, eliminating the need for separate complete anechoic chambers for each test scenario.
Solution Approach 2:
The second chamber serves multiple purposes by being configurable with different inner wall types. It can function as an extension of the anechoic chamber for open space testing or as a separate environment for urban area simulation, reducing the total equipment quantity needed.
3Adaptability or versatility
If multiple anechoic chambers are used to simulate various test environments, then test environment diversity is improved, but test time and manpower increase
Solution Approach 1:
The system introduces dynamic reconfigurability through the second chamber, which can be quickly adjusted between wave-absorbing and wave-reflecting configurations. This dynamic capability allows test environments to be changed without building or moving entire chambers, significantly reducing the time and manpower required for environment transitions.

AI summary
An anechoic chamber includes a closed chamber and a metal container. The closed chamber includes wave-absorbing inner walls located therein, and the wave-absorbing inner walls collectively define a first accommodation space. Each of the wave-absorbing inner walls includes wave absorbers arranged thereon. The metal container is removably received in the first accommodation space, and has wave-reflecting inner walls located therein. The wave-reflecting inner walls collectively define a second accommodation space which is used to receive a device under test (DUT).
