Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional smartphone-based controllers are used to provide physical buttons for users to run games smoothly, then tactile feedback and ease of operation are improved, but the device size becomes large and cannot fit into small spaces
Solution Approach 1:
The controller is designed with a nested structure where the second controller can be folded into the first controller, and the retractable part can be stored within the controller body. This nesting approach allows the controller to provide full functionality when needed while reducing to a compact size for portability.
Solution Approach 2:
The controller incorporates dynamic elements including a retractable part that can extend and retract, and pivot joints that allow the controllers to fold relative to each other. These dynamic features enable the controller to transition between an extended operational state and a compact stored state, resolving the contradiction between size and functionality.
2Ease of operation
If the controller is extended to provide full functionality and stability, then ease of operation is improved, but the device occupies more space and reduces portability
Solution Approach 1:
The controller uses dynamic mechanisms including a retractable part that can extend to provide full functionality during use and retract to minimize length for portability. The pivot joints enable the controllers to fold, allowing the device to transition between extended and compact configurations dynamically.
Solution Approach 2:
The controller is divided into separable components including a first controller, a second controller, a retractable part, and pivot joints. This segmentation allows each component to be independently positioned and folded, enabling the controller to reduce its overall length while maintaining full functionality when extended.
3Volume of moving object
If the controller is designed to be compact for portability, then volume is reduced and portability is improved, but the stability and tactile feedback may be compromised
Solution Approach 1:
The controller employs a nested structure where the second controller folds into the first controller, and the retractable part stores within the controller body. This nesting maintains a compact volume while preserving the complete controller structure for stability during operation.
Solution Approach 2:
The dynamic design with retractable parts and pivot joints allows the controller to achieve a compact volume for portability when folded, while maintaining structural stability and full functionality when extended to the operational position.

AI summary
A control assembly includes two controllers and a retractable and foldable mechanism including a retractable part and two pivot joints, the two pivot joints are respectively pivotally connected to two opposite ends of the retractable part, the two controllers are respectively pivotally connected to the two pivot joints so that the two controllers are movably connected to the retractable part via the two pivot joints, respectively.
