Snap-Fit Rocker Assembly for Replaceable Controller Joysticks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rocker devices for controllers, such as those for unmanned aerial vehicles and gamepads, are prone to damage due to continuous shaking, necessitating frequent replacements. However, the welding connection method used in current designs makes it difficult for users to disassemble and replace the rocker devices independently.
Innovation Solution
A rocker device with a mounting base and a rocker assembly that utilizes a snapping connection method, allowing for quick disassembly and assembly. The rocker assembly is electrically connected to the controller for multi-directional control, and the snapping mechanism enables easy replacement of the rocker assembly without the need for specialized tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding connection method is used to connect the rocker device and the controller PCB board, then the connection strength is improved, but the ease of disassembly and assembly deteriorates
Solution Approach 1:
The rocker device is segmented into a rocker assembly and a mounting base that can be independently connected and disconnected. The mounting base is separated from the controller PCB board, allowing the rocker assembly to be replaced without affecting the entire controller structure. This segmentation enables the connection to be both strong during use and easily separable when replacement is needed.
Solution Approach 2:
The mounting base acts as an intermediary component between the rocker assembly and the controller PCB board. It provides a standardized interface with positioning slots and guiding portions that enable tool-free attachment and detachment. The mounting base absorbs the mechanical stress of connection while allowing simple snap-fit or screw-based attachment methods, resolving the contradiction between strong connection and easy disassembly.
2Adaptability or versatility
If the rocker device is designed for continuous shaking operation, then the control functionality is improved, but the reliability deteriorates due to increased damage risk
Solution Approach 1:
The rocker assembly is designed as a replaceable component that can be easily discarded when damaged and replaced with a new one. The standardized mounting interface allows users to quickly swap out the rocker assembly without requiring specialized tools or technical expertise. This approach accepts that the rocker will eventually fail due to continuous shaking but minimizes the overall system downtime and maintenance cost.
Solution Approach 2:
By separating the rocker assembly from the mounting base and controller, the design allows only the worn rocker portion to be replaced while retaining the durable mounting base and controller components. This segmentation prevents complete system replacement and extends the overall system life by allowing incremental maintenance.
3Ease of operation
If the rocker assembly is made detachable from the mounting base, then the ease of replacement is improved, but the device complexity increases
Solution Approach 1:
The mounting base is designed with a universal interface that can accommodate different rocker assembly variations while maintaining the same attachment mechanism. The positioning slots and guiding portions are standardized features that work with multiple rocker designs, reducing the need for custom mounting solutions for each rocker type. This universality simplifies the overall system despite the detachable design.
Solution Approach 2:
The mounting base incorporates self-aligning features such as guiding portions and positioning slots that automatically guide the rocker assembly into the correct position during attachment. This self-service mechanism eliminates the need for complex alignment procedures or specialized installation tools, making the detachable design simple to use despite the additional structural elements.
