Multi-Mode Shifter Lever Structure for Remote Controller Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shifter lever structures for remote controllers, such as those for single-lens reflex cameras and unmanned aerial vehicles, typically provide only a single operating function, making it inconvenient for operators to perform multiple functions due to the limited moving range of fingers, requiring cooperation with multiple shifter lever structures or separate control structures.
Innovation Solution
A shifter lever structure with a press key and shifter lever that can move in different modes, such as sliding and rotating, coupled with sensors to obtain movement state information, allowing for the emission of control signals via a controller and signal emission device, enabling the performance of multiple operating functions with a single structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single shifter lever structure is used, then the device complexity is reduced, but the adaptability or versatility is limited
Solution Approach 1:
The shifter lever structure is designed to perform multiple operating functions through different movement modes. The press key can slide along the lengthwise direction of the shifter lever, the shifter lever can rotate around the press key, and combinations of these movements are possible. This multi-functional design allows a single structure to replace what would traditionally require multiple separate control structures, thereby improving versatility while maintaining simplicity.
2Adaptability or versatility
If multiple shifter lever structures are used to provide multiple operating functions, then the adaptability or versatility is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple control functions into a single integrated shifter lever structure. The press key and shifter lever are combined in such a way that one structure can perform multiple operations: pressing the press key, sliding the press key along the shifter lever, rotating the shifter lever around the press key, and combinations thereof. This consolidation reduces the number of separate control structures needed, thereby reducing device complexity while maintaining multi-functionality.
3Ease of manufacture
If conventional shifter lever structures are used, then the ease of manufacture is maintained, but the ease of operation is reduced due to limited finger moving range
Solution Approach 1:
The shifter lever structure incorporates dynamic movement capabilities that adapt to the operator's finger movements. The press key can slide along the shifter lever in the lengthwise direction, and the shifter lever can rotate around the press key. These dynamic movements expand the operational range beyond what a static structure would allow, making it easier to operate while still being manufacturable using conventional techniques.

AI summary
A remote controller comprises a shifter lever structure, a controller, and a signal emission device. The shifter lever structure comprises a base, a press key movably connected to the base, a shifter lever arranged surrounding the press key and movably connected to the base, and a sensor coupled to the press key and the shifter lever and configured to obtain moving state information about the press key and the shifter lever. A movement mode of the shifter lever is different from a movement mode of the press key. The controller is electrically coupled to the sensor. The signal emission device is electrically coupled to the controller. The controller is configured to receive the moving state information from the sensor and emit a control signal corresponding to the moving state information via the signal emission device.
