Multi-Axis Stick Force Feedback Through Segmented Driven Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing operation devices struggle to provide a precise force sensation in one-dimensional trigger operations and fail to expand this technology to two-dimensional or three-dimensional stick operations.
Innovation Solution
The proposed operation device includes an operation unit, a first movable unit, a first drive unit, and a first driven unit, enabling the operation unit to move within a predetermined range and presenting a force sensation by moving an abutting portion of the first movable unit according to the driving force of the first drive unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a force sensation is presented using precise control in a one-dimensional trigger operation, then the force sensation accuracy is improved, but the technology cannot be expanded to two-dimensional or three-dimensional stick operations
Solution Approach 1:
The driven unit is divided into multiple independent components (first driven unit and second driven unit) that can move independently in different directions. Each driven unit has its own abutting portion that can contact the movable unit at different positions, enabling multi-dimensional force sensation control while maintaining precise control capabilities
Solution Approach 2:
The operation device is designed to handle both one-dimensional trigger operations and two-dimensional/three-dimensional stick operations using the same force sensation presentation mechanism. The movable unit can be moved by multiple driven units in different directions, making the device universally applicable to various operation types without requiring separate systems
2Ease of operation
If the operation device presents a force sensation in multi-dimensional stick operations, then the operational feeling is improved, but the device complexity increases
Solution Approach 1:
Multiple driven units and their corresponding abutting portions are merged into a single integrated system that works together to provide force sensation. The movable unit serves as a common interface that receives control inputs and transmits force sensation to the operation unit, consolidating multiple functions into a unified structure
Solution Approach 2:
The abutting portions of the driven units are positioned such that they can contact the movable unit at different locations in a nested or layered arrangement. This allows multiple driven units to operate within the same spatial envelope without requiring separate complex structures for each dimension
