Vibration Testing Device Direct Energy Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration testing devices for electronic devices absorb some of the vibration energy through the base, leading to inaccurate test results due to energy loss, which affects the measurement of vibration strength and frequency.
Innovation Solution
A vibration testing device design that includes a vibration contact member, a transmission member, and a resilient member, where the transmission member is rigidly connected to the vibration contact member and extends through a ladder-shaped receiving hole in the base, allowing direct transmission of vibration energy from the electronic device to the contact member without absorption by the base, and the resilient member compresses to maintain contact without direct base contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the vibration contact member is directly attached to the base, then the structure is simple and easy to manufacture, but vibration energy is absorbed by the base resulting in inaccurate measurement
Solution Approach 1:
The patent introduces a transmission member as an intermediary component between the electronic device and the vibration contact member. This transmission member directly transmits vibration energy from the electronic device to the contact member without passing through the base, thereby eliminating the base's vibration absorption effect while maintaining structural simplicity.
2Device complexity
If the vibration contact member is directly attached to the base, then the device complexity is low, but vibration energy loss occurs through the base
Solution Approach 1:
The transmission member serves as a dedicated intermediary that establishes a direct vibration transmission path from the electronic device to the contact member, bypassing the base entirely. This eliminates energy loss through the base while adding minimal structural complexity.
Solution Approach 2:
The vibration transmission path is segmented into distinct components: the electronic device, the transmission member, and the vibration contact member. This segmentation isolates the vibration transmission function from the base structure, preventing energy absorption by the base while maintaining overall device simplicity.

AI summary
A vibration testing device to test vibration strength and frequency generated by an electronic device, includes a base, a vibration contact member, a transmission member, and a resilient member attached to the transmission member. The base includes a receiving space to receive the electronic device and a receiving hole in communication with the receiving space. The transmission member extends through the receiving hole and is rigidly attached to the vibration contact member. During testing, the electronic device directly abuts an end portion of the transmission member so that the vibration strength and frequency generated by the electronic device are directly transmitted to the vibration contact member.
