Input Device Magnetic Stabilization for Slide Wobbling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing input apparatuses fail to effectively prevent wobbling of the slide member due to the magnets being disposed away from each other, leading to instability when no pressing operation is performed.
Innovation Solution
An input apparatus configuration that includes a first magnetic substance attached to the casing, a second magnetic substance attached to the slide member, and a third magnetic substance that comes into contact with both when the slide member is not receiving an operating force, ensuring the third magnetic substance remains attracted to either the first or second magnetic substance to prevent wobbling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the first magnet and the second magnet are disposed away from each other, then the structure is simpler and manufacturing is easier, but the wobbling of the slide member cannot be eliminated
Solution Approach 1:
A third magnetic substance is introduced as an intermediary between the first and second magnets. This third magnet comes into contact with both the first and second magnets, creating a magnetic bridge that stabilizes the slide member without requiring the first and second magnets to be in direct contact or disposed close to each other, thus maintaining ease of manufacture while achieving stability
2Stability of the object's composition
If the first magnet and the second magnet are disposed close to each other to prevent wobbling, then stability is improved, but the device complexity increases
Solution Approach 1:
The magnetic stabilization function is segmented into three separate magnetic substances: a first magnet attached to the slide member, a second magnet attached to the housing, and a third magnet that contacts both. This segmentation allows each component to be simpler and easier to manufacture individually, while collectively achieving the stability function without requiring complex arrangements of fewer components
3Ease of manufacture
If magnets are disposed away from each other, then manufacturing cost is reduced, but wobbling prevention is insufficient
Solution Approach 1:
The third magnetic substance serves as a magnetic intermediary that connects the first and second magnets indirectly. This allows the first and second magnets to be disposed away from each other, reducing manufacturing cost, while the third magnet ensures reliable magnetic coupling to prevent wobbling, thus maintaining reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces or prevents wobbling of the movable member by maintaining magnetic attraction when no operating force is applied, enhancing stability and reducing manufacturing costs by using a magnet only for the third magnetic substance.
Implementation Method 1
a third magnetic substance 15 that comes into contact with each of the first magnetic substance 13 and the second magnetic substance 14 when the slide member 11 is not receiving an operating force
