Solution Overview
Problem
Existing radio control transmitters require time and effort to change the elastic plate for different model types, such as planes and helicopters, to adjust click feeling and resistance, and lack a suitable option for model gliders.
Innovation Solution
A stick device with a magnet brake using magneto-rheological fluid, controlled by a variable resistor and A/D converter, allows for adjustable click feeling and resistance without physical plate changes, enabling users to set preferred operational feelings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different elastic plates are used for different model types, then the click feeling and resistance can be optimized for each model type, but the device complexity and time required for replacement increase
Solution Approach 1:
The patent replaces multiple model-specific elastic plates with a single universal elastic plate that can be used across different model types. The magnet brake system provides electronically adjustable resistance that adapts to different model requirements, eliminating the need for physical plate changes while maintaining optimal performance for various models including planes, helicopters, and gliders.
Solution Approach 2:
The patent uses a magnet brake with controllable magnetic field strength to dynamically adjust resistance parameters. By changing the current to the magnet brake coil, the system can simulate different elastic plate characteristics without physically replacing plates, allowing users to optimize click feeling and resistance for different model types through electronic parameter adjustment rather than mechanical component changes.
2Ease of operation
If elastic plates are replaced for different model types, then the operational feeling can be optimized, but the time and effort required for adjustment increase
Solution Approach 1:
The patent replaces the mechanical elastic plate system with an electromagnetic magnet brake system. Instead of physically replacing elastic plates to change operational characteristics, users adjust the magnetic field strength through electronic control, enabling rapid adaptation to different model types without manual disassembly or component replacement.
Solution Approach 2:
The patent introduces dynamic adjustability to the resistance mechanism through the magnet brake system. The magnetic resistance can be continuously adjusted during operation or between uses, allowing users to optimize operational feeling for different model types without the static, fixed characteristics of physical elastic plates. This dynamic control eliminates the time-consuming replacement process entirely.
3Device complexity
If a single elastic plate is used for all model types, then the device complexity is reduced, but the operational feeling becomes inappropriate for some models
Solution Approach 1:
The patent uses variable magnetic field strength in the magnet brake to compensate for the lack of physical plate variations. By adjusting the current to the magnet brake coil, the system can simulate the different mechanical characteristics of various elastic plates, providing model-appropriate operational feeling while maintaining a single universal elastic plate design.
Solution Approach 2:
The magnet brake system serves multiple functions: it provides friction resistance, generates click feeling, and simulates different elastic plate characteristics for various model types. This multi-functional electromagnetic system replaces what would otherwise require multiple specialized mechanical components, achieving universality while maintaining adaptability.
4Manufacturing precision
If multiple elastic plates are provided for different models, then the precision of operational control is improved, but the ease of manufacture decreases
Solution Approach 1:
The patent replaces the need to manufacture and inventory multiple precision-matched elastic plates with a single elastic plate and an electronically controlled magnet brake system. The magnetic resistance provides precise, adjustable control characteristics without requiring custom manufacturing for each model type, simplifying the manufacturing process while maintaining or improving operational precision.

Data Source
AI summary
Inside a stick base, a variable resistor and a magnet brake are attached to a turnable first bridge. An A/D converter adapted to convert an analog value corresponding to a turning angle, which is obtained from the variable resistor, to a digital value, and a controller adapted to drive the magnet brake when a signal from the A/D converter is given and coincides with a predetermined value are provided. On the basis of data retained in a memory, current is applied to a coil of the magnet brake. Doing so makes it possible to electrically change operational feeling when turning a stick.
