Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi direction switches have static portions on a single printed circuit board, leading to potential incorrect connections and a lack of clear separation between restoring forces for moving plates, which can result in erroneous signal generation.
Innovation Solution
A multi direction switch design featuring two static detecting mechanisms on separate covers and movable mechanisms that allow movement in orthogonal directions, preventing incorrect circuit connections and ensuring distinct signal generation through impedance changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two static portions are formed on the same printed circuit board, then the device structure is simplified, but incorrect circuit connections may occur and signal reliability deteriorates
Solution Approach 1:
The patent divides the detecting mechanisms into separate components: first and second static detecting mechanisms are formed on different covers, while first and second movable detecting mechanisms are on separate moving bodies. This segmentation prevents incorrect circuit connections by physically separating the circuits, thus improving signal reliability while maintaining manageable device complexity through modular design.
Solution Approach 2:
The patent introduces separate covers as intermediary structures to hold the static detecting mechanisms. These covers act as mediators that physically isolate the circuits connected to the static portions, preventing wrong conduction between circuits while still allowing the moving bodies to interact with the static detecting mechanisms for signal generation.
2Device complexity
If a single spring member is used to return the button, then the structure is simplified, but the restoring force may not be clearly separated for each moving plate leading to erroneous signals
Solution Approach 1:
The patent segments the restoring force mechanism by providing separate first and second spring members, where the first spring member returns the first moving body along the first direction and the second spring member returns the second moving body along the second direction. This segmentation ensures that each moving body has its own dedicated restoring force, preventing erroneous signal generation while maintaining clear directional control.

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 solution effectively prevents incorrect circuit connections and ensures reliable signal generation by utilizing separate static and movable detecting mechanisms on distinct covers, enhancing the accuracy and reliability of signal transmission.
Implementation Method 1
an elastic mechanism (6) assembled around a periphery of the pair of moving bodies (51, 52)... a restoring force provided by the spring member is exerted to the button firstly and to drive the moving plates nextly

AI summary
A multi direction switch (100) includes a first cover (31) having a first static detecting mechanism (3132), a second cover (32) having a second static detecting mechanism (3232), a first moving body (51) having a first movable detecting mechanism (513), a second moving body (52) having a second movable detecting mechanism (523), and an actuating mechanism. The second movable detecting mechanism is movable relative to the second static detecting mechanism in response to a movement of the second moving body along a first direction. The first movable detecting mechanism is movable relative to the first static detecting mechanism in response to a movement of said first moving body along a second direction perpendicular to the first direction.
