Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electromagnetic induction joystick potentiometers require separate design and manufacturing of handle and magnetic induction circuit boards, leading to higher manufacturing costs and complex assembly processes due to the need for surface-mount technology (SMT) on both boards.
Innovation Solution
A split-type electromagnetic induction joystick potentiometer design where the magnetic induction chip is directly welded onto a handle circuit board, eliminating the need for a separate magnetic induction circuit board, and allowing separate manufacturing of the handle circuit board and joystick mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate magnetic induction circuit board is designed and manufactured, then the magnetic induction chip can be properly installed, but the manufacturing cost increases and the assembly process becomes more complex
Solution Approach 1:
The patent merges the magnetic induction circuit board with the handle circuit board into a single integrated circuit board. The magnetic induction chip is directly mounted on the handle circuit board, eliminating the need for a separate magnetic induction circuit board. This integration reduces the number of components, simplifies the assembly process, and lowers manufacturing costs while maintaining the functional reliability of the magnetic induction chip installation.
2Ease of manufacture
If two types of circuit boards are manufactured separately, then the magnetic induction chip can be welded using SMT process, but the manufacturing cost increases
Solution Approach 1:
The patent combines the magnetic induction circuit board and handle circuit board into a single integrated circuit board, allowing all electronic components including the magnetic induction chip to be welded using the SMT process in one manufacturing step. This eliminates the need to manufacture two separate types of circuit boards, reducing material costs, manufacturing overhead, and assembly costs while maintaining the ease of SMT welding process.
3Reliability
If the magnetic induction circuit board is installed inside the joystick mechanism assembly, then the magnetic interaction can be achieved, but the assembly and testing process becomes more complicated
Solution Approach 1:
The patent integrates the magnetic induction circuit board with the handle circuit board, allowing the magnetic induction chip to be directly mounted on the handle circuit board. This integration eliminates the separate installation step of mounting the magnetic induction circuit board inside the joystick mechanism assembly, simplifying the assembly and testing process while maintaining the magnetic interaction functionality between the permanent magnet and the magnetic induction chip.

Function Achieved in This Case
Simplifies manufacturing and assembly processes, reduces costs by eliminating the need for a separate magnetic induction circuit board, and enables efficient magnetic interaction for signal output through the magnetic induction chip on the handle circuit board.
Implementation Method 1
The permanent magnet interacts magnetically with the magnetic induction chip on the handle circuit board, thus making the magnetic induction chip on the handle circuit board sense changes in magnetic field strength and output induction signals

AI summary
A split-type electromagnetic induction joystick potentiometer includes a handle circuit board provided with at least one joystick mechanism installation position and at least one joystick mechanism installed on the at least one joystick mechanism installation position. Each joystick mechanism installation position is welded with a magnetic induction chip. Each joystick mechanism includes a base, a sliding disc, a spring, a joystick, a rocker arm, an upper cover and a housing. The magnetic induction chip is directly welded onto the handle circuit board, without the need for separate design and manufacturing of a magnetic induction circuit board to weld the magnetic induction chip. Each joystick mechanism of the disclosure itself is not installed with the magnetic induction circuit board, thereby simplifying the manufacturing and assembly process of the split-type electromagnetic induction joystick potentiometer, and reducing the manufacturing costs. The permanent magnet can interact magnetically with the magnetic induction chip.
