Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration detecting devices often face inconvenience due to their complex structure and difficulty in minimizing vibration noise, which can lead to malfunctions or failures.
Innovation Solution
A vibration detecting device is designed with a housing, vibration sensor, circuit board, flexible wiring member, and an elastic member made of polymer material, where the circuit board is held by the housing through the elastic member, and the elastic member is detachable, reducing vibration transmission and resonance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the circuit board is rigidly fixed to the housing, then structural stability is improved, but vibration noise transmission to the vibration sensor increases
Solution Approach 1:
An elastic member is introduced as an intermediary component between the circuit board and the housing. This elastic member serves as a mediator that provides mechanical support while attenuating vibration noise, thus resolving the contradiction between structural stability and vibration noise transmission.
Solution Approach 2:
The elastic member is pre-installed between the circuit board and the housing to provide cushioning before vibration noise can transmit. This prior cushioning approach prevents vibration noise from reaching the vibration sensor while maintaining structural stability.
2Ease of manufacture
If conventional fixed structures are used, then manufacturing simplicity is improved, but ease of repair and replacement deteriorates
Solution Approach 1:
The mounting structure is segmented into separate components: the housing, the elastic member, and the circuit board. This segmentation allows the circuit board to be easily detached from the housing by removing the elastic member, significantly improving ease of repair and replacement while maintaining manufacturing simplicity.
3Object-affected harmful factors
If complex vibration isolation structures are used, then vibration noise attenuation is improved, but device complexity increases
Solution Approach 1:
The vibration isolation function is extracted as a separate elastic member component rather than being integrated into the housing or circuit board structure. This extraction approach achieves effective vibration noise attenuation while keeping the overall device structure simple and easy to understand.
