Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate input devices are used to simulate different vehicle control mechanisms (sequential shifter and handbrake), then the realism and functionality of the simulator is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines a sequential shifter mechanism and a handbrake mechanism into a single input device housing. The actuator can be configured to perform either function by connecting to different connectors, allowing one physical device to replace multiple separate devices and reduce overall system complexity
Solution Approach 2:
The actuator is designed with multi-functionality, capable of operating in different modes by connecting to different connectors. When connected to the first connector, it functions as a sequential shifter; when connected to the second connector, it functions as a handbrake, making the component universal and adaptable to different simulation needs
2Adaptability or versatility
If multiple separate input devices are used to simulate different vehicle control mechanisms, then the realism of the gaming experience is improved, but the number of components and manufacturing complexity increases
Solution Approach 1:
The patent merges multiple control mechanisms into a single manufacturable unit. The housing contains multiple connectors and an actuator that can be configured for different functions, allowing manufacturers to produce one standardized component that replaces the need to manufacture and assemble multiple separate devices
Solution Approach 2:
The actuator is segmented with multiple connectors that can be selectively engaged. This segmentation allows the same base component to be configured for different functions through simple connector selection rather than requiring different manufactured parts for each function
3Adaptability or versatility
If the actuator is configured between different modes by connecting to different connectors, then the versatility of the input device is improved, but the complexity of configuration and operation increases
Solution Approach 1:
The device incorporates a detent mechanism with spring-loaded balls that automatically engage with detent blocks when connectors are inserted. This self-service feature provides automatic configuration and tactile feedback, eliminating the need for complex manual setup procedures or technical knowledge to switch between modes
4Adaptability or versatility
If different spring forces are used for different modes, then the operational characteristics for each function are improved, but the complexity of the spring mechanism increases
Solution Approach 1:
Different spring forces are applied locally to the actuator depending on which connector is engaged. The first spring provides a first force when connected to the first connector (sequential shifter mode), while the second spring provides a second force when connected to the second connector (handbrake mode), allowing each function to have optimized characteristics without requiring a complex variable spring system
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Reduces the number of input devices needed and simplifies manufacturing by allowing a single device to simulate multiple control functions, providing a realistic gaming experience with adjustable resistance and tactile feedback.
Implementation Method 1
A spring force of the spring may be variable such that the spring force increases as a displacement of the actuator in the first direction increases
Implementation Method 2
The input devices may include a detent mechanism that is engaged when the actuator is in the first mode and that is disengaged when the actuator is in the second mode

AI summary
Dual-function input devices for a computing device may include a housing and an actuator disposed within the housing. The actuator may be pivotable relative to the housing in a first direction and a second direction. The actuator may include a first connector and a second connector. The input devices may include an input lever that is coupleable with the actuator via one of the first connector and the second connector. The actuator may be configurable between a first mode by coupling the input lever with the first connector and a second mode by coupling the input lever with the second connector. In the first mode the input lever and the actuator may be pivotable in the first direction by a first distance. In the second mode the input lever and the actuator may be pivotable in the first direction by a second distance that is greater than the first distance.
