Single-Hand Multi-DoF Controller With Directional Haptic Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional control systems require both hands to manage multiple degrees of freedom for navigating objects, leading to potential errors due to hand coordination issues.
Innovation Solution
A modular hand controller with multiple control members, including a first control member movable with one or two independent degrees of freedom, a second control member movable with three independent degrees of freedom, and a third control member, allowing a user to control a target object using a single hand, along with a forearm brace featuring a quick-release mechanism for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple discrete controllers are used to control navigational parameters, then control capability is improved, but device complexity and ease of operation deteriorate due to requiring both hands
Solution Approach 1:
The patent combines multiple discrete controllers (joystick, control column, cyclic stick, foot pedals) into a single integrated controller that can be operated with one hand. The first control member provides pitch and roll control, the second control member provides yaw control, and the third control member provides thrust control, all unified in one device that replaces multiple separate controllers requiring both hands to operate.
Solution Approach 2:
The single hand-operable controller performs multiple control functions that traditionally required separate devices. The first control member controls pitch and roll, the second control member controls yaw, and the third control member controls thrust, making the controller universal for managing all primary navigational parameters of the aerial vehicle.
2Measurement precision
If multiple discrete controllers are used, then control precision is improved, but reliability deteriorates due to hand coordination errors
Solution Approach 1:
By merging multiple control functions into a single hand-operable device, the patent eliminates the coordination errors that occur when operators must simultaneously manage multiple separate controllers with both hands. The unified design ensures that all control inputs originate from one hand, removing the source of coordination mistakes while preserving precise control over all navigational parameters.
3Ease of operation
If a single hand controller is used, then ease of operation is improved, but device complexity increases due to integrating multiple DoFs
Solution Approach 1:
The controller is segmented into three distinct control members, each responsible for specific degrees of freedom. The first control member handles pitch and roll (two DoFs), the second control member handles yaw (one DoF), and the third control member handles thrust (one DoF). This segmentation allows complex multi-DoF control to be broken down into manageable, independently operable components that can be controlled by a single hand.
4Volume of moving object
If control members are coupled together, then space efficiency is improved, but ease of repair deteriorates due to interconnected structure
Solution Approach 1:
The controller is designed as a modular assembly of three distinct control members that are coupled together but can be independently accessed and serviced. Each control member is a separate component with its own mounting structure, allowing technicians to remove, repair, or replace individual members without disassembling the entire controller assembly, thus maintaining ease of repair despite the integrated design.

AI summary
A controller includes a first control member movable with one or two degree(s) of freedom (DoF) a second control member coupled to the first control member and movable with three independent DoFs and a third control member coupled to the first and the second control members, the third control member movable with one DoF, which is being one of the three DoFs of the second control member in the set, and providing a third control input, wherein the first, the second, and the third control members are configured to be operated by a user's single hand. Further, a forearm brace for attaching to a forearm of a user and a controller is used to support the user's forearm when the user operates the controller. Additionally, the controller includes vibration haptic motors for provide haptic alerts to the user based on position data and/or orientation data associated with a target object.
