Thin Vibration Structure With Nested Cushioning to Prevent Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration structures for electronic devices become bulky due to the thickness of the member connecting the vibration device and the housing, and when this member is thinned to reduce bulkiness, the housing can impede the vibration of the device.
Innovation Solution
A vibration structure that includes a member with a vibrator configured to vibrate along a plane direction, a housing to hold the member, and a cushioning material connecting the housing to the member, where the thickness of the cushioning material in a direction orthogonal to the plane direction of the housing is greater than the length of the gap between the member and the housing, allowing the cushioning material to enter the housing side and reduce the overall thickness of the structure while minimizing vibration restraint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the member connecting the vibration device and the housing is thinned to suppress bulkiness, then the thickness of the vibration structure is reduced, but the housing easily restrains the vibration device
Solution Approach 1:
A cushioning material is introduced as an intermediary element between the vibration device and the housing. This cushioning material has a thickness greater than the gap between the member and the housing, allowing it to enter the housing side (through cutouts or cavities) and reduce overall thickness while simultaneously preventing the housing from restraining the vibration device during operation
Solution Approach 2:
The cushioning material is positioned to enter into the housing structure through cutouts or cavities, effectively nesting part of the cushioning material within the housing space. This nesting arrangement reduces the external thickness of the vibration structure while maintaining the cushioning function to prevent restraint of the vibration device

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The proposed vibration structure effectively reduces bulkiness while preventing the housing from impeding the vibration, ensuring that the vibration structure remains thin and functional within electronic devices.
Implementation Method 1
a cushioning material connecting the housing to the member, in which a thickness of the cushioning material in a direction orthogonal to a plane direction of the housing is greater than a length of a gap between the member and the housing
