Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaft joysticks are lightweight and prone to movement during operation, leading to reduced input accuracy and unideal user experience, especially when using antiskid pads or suction disks, and are limited by plastic materials.
Innovation Solution
A shaft joystick design that includes an upper and lower cover body with a detachable weight stack between them, an antiskid pad, and a balanced center of gravity, along with a storage cavity for a USB data wire, enhancing stability and input accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the shaft joystick is made lightweight using plastic materials, then the ease of manufacture is improved, but the stability during operation deteriorates
Solution Approach 1:
The patent applies composite materials by combining plastic housing with metal weight stacks. The weight stacks are detachably assembled between the upper and lower cover bodies, creating a composite structure that leverages the manufacturing ease of plastic while adding the weight and stability of metal components. This resolves the contradiction by integrating materials with complementary properties.
Solution Approach 2:
The patent segments the joystick into modular components: a plastic housing structure and separate metal weight stacks. The weight stacks can be independently assembled, disassembled, and adjusted, allowing the manufacturer to produce the housing separately and add weight modules as needed. This segmentation enables ease of manufacture for the main body while providing flexibility to enhance stability through optional weight additions.
2Stability of the object's composition
If antiskid pads or suction disks are used to increase friction, then the stability is improved, but the input accuracy deteriorates due to movement during operation
Solution Approach 1:
The patent uses weight stacks as counterweights positioned within the joystick housing. These weights increase the overall mass and lower the center of gravity, creating a stabilizing effect that counteracts the tendency of the joystick to move during operation. By adding weight rather than relying solely on friction-enhancing pads, the joystick achieves stability through inertial resistance, which does not interfere with input accuracy.
3Stability of the object's composition
If the weight of the shaft joystick is increased, then the stability is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent implements dynamic adjustability by making the weight stacks detachable and interchangeable. Users can adjust the total weight by adding or removing weight stacks according to their preferences or specific usage scenarios. This dynamic configuration allows the joystick to adapt between being lighter for easier handling and heavier for enhanced stability, resolving the contradiction through user-adjustable parameters.

AI summary
A shaft joystick is provided, which relates to the technical field of game peripherals. The shaft joystick includes an upper cover body, a lower cover body and a lever; the lower cover body is provided with an antiskid pad; at least one weight stack is detachably assembled between the upper cover body and the lower cover body; and a circumferential side of the weight stack is locked to the lower cover body. An accommodating slot for mounting the weight stack is formed in the lower cover body; and a bolt hole for locking the weight stack is formed in the circumferential side of a bottom of the accommodating slot. By the adoption of the above technical solution, the shaft joystick has the advantages of improving the input accuracy of the joystick and enhancing the input experience of the shaft joystick for users.
