Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing joystick controllers in game players lack accuracy, impacting the overall gaming experience due to inefficiencies in detecting user input and adjusting operational forces.
Innovation Solution
A controller assembly comprising a driving unit, sliding member, potentiometer, and controlling module that adjusts the sliding member's position and operating force in real-time by comparing detected rotation information and user input with preset values, using a worm wheel and worm mechanism to enhance accuracy and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional joystick controller is used, then the structure is simple, but the accuracy of detecting user input is insufficient
Solution Approach 1:
The controller assembly is divided into multiple functional modules: a driving unit with motor, a sliding member, a potentiometer for detection, and a controlling module. This segmentation allows each component to specialize in one function, improving detection accuracy while keeping the overall structure organized and manageable.
Solution Approach 2:
The potentiometer detects the rotation angle of the worm wheel and provides feedback to the controlling module. The controlling module processes this feedback signal to determine the sliding member's position and adjusts the driving mechanism accordingly, creating a closed-loop feedback system that enhances detection accuracy.
2Manufacturing precision
If the sliding member position is fixed, then the structure is simple, but the operating force accuracy is insufficient
Solution Approach 1:
The sliding member's position is made dynamic rather than fixed. The driving mechanism, controlled by the controlling module based on potentiometer feedback, continuously adjusts the sliding member's position along the worm wheel's central axis. This dynamic adjustment capability enables precise control of operating force, improving manufacturing precision while the modular structure keeps complexity manageable.

AI summary
A controller assembly functioning as a joystick includes a driving unit, a sliding member, a potentiometer, and a controlling module. The driving unit includes a driving mechanism, a worm, and a worm wheel, the worm wheel connected to the sliding member. Through the worm, the driving mechanism rotates the worm wheel, causing the sliding member to move up and down only. The potentiometer detects rotation of the worm wheel, the controlling module obtains movement accordingly of the sliding member. The controlling module obtains a user's operating force applied to the driving mechanism, and compares the positional information and the operating force information with preset values to obtain comparison results. The sliding member is driven to move according to the two comparison results. An electronic device with the controller assembly is also disclosed.
