Gimbal Joystick Throttle Layout for Precise 6-Axis Spacecraft Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game control schemes for spacecraft in games, such as HOSAS, omnidirectional throttle, and HOTAS, fail to achieve precise control along axes 5 and 6 due to ergonomic limitations and anatomical constraints, leading to inadequate control precision and accuracy.
Innovation Solution
A game joystick with a control grip, gimbal, and throttle base, featuring damping-adjustable structures and magnetic induction chips to detect rotations, allowing precise control of spacecraft motion and throttle operations through a gimbal mechanism that enables automatic returning and adjustable damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the omnidirectional throttle scheme is used, then all axes intuitively correspond to the direction of motion of the spacecraft, but the control precision along axis 5 and axis 6 is still unsatisfactory
Solution Approach 1:
The control device is segmented into two independent control mechanisms: a throttle mechanism for forward-backward motion (axis 1) and a joystick mechanism for lateral motions (axes 5 and 6). This segmentation allows each mechanism to be optimized for its specific function, with the joystick providing precise control for lateral movements while the throttle handles forward-backward control.
2Adaptability or versatility
If the HOTAS scheme is used, then the right-hand joystick controls pitch, roll, and yaw, but the control precision and accuracy along axis 5 and axis 6 cannot be achieved due to small linear motion range and anatomical constraints
Solution Approach 1:
The control functions are segmented between two hands: the right hand operates the joystick for lateral motions (axes 5 and 6) where precision is critical, while the left hand operates the throttle for forward-backward control (axis 1). This segmentation assigns precision-critical controls to the hand better suited for fine movements.
Solution Approach 2:
The patent inverts the conventional HOTAS assignment by giving the joystick to the right hand and the throttle to the left hand, rather than the traditional assignment. This inversion allows the right hand, which typically has finer motor control, to operate the precision-critical joystick for lateral movements.
3Ease of operation
If one finger controls up and down axes and left and right axes, then the control device can be operated with one hand, but the human hand cannot perform small and precise motions quickly and simultaneously with one finger
Solution Approach 1:
The control functions are segmented between two hands, with each hand responsible for specific axes. The right hand controls lateral motions (axes 5 and 6) requiring precision, while the left hand controls forward-backward motion (axis 1). This eliminates the need for one finger to control multiple precision-critical axes simultaneously.

AI summary
The present disclosure discloses a game joystick, including a control grip, a gimbal, and a throttle base; a throttle assembly is arranged in the throttle base; an upper end of the gimbal is connected to the control grip; a lower end of the gimbal is connected to the throttle assembly; the control grip is pushed with a hand forwards, backwards, leftwards, or rightwards, so that the control grip can tilts forwards, backwards, leftwards, and rightwards relative to the throttle base; after the pressure on the control grip is relieved, the control grip can achieve automatic returning and resetting; and the control grip is overall pushed forwards or pulled backwards with an arm to drive the throttle assembly to achieve throttling up or throttling down. According to the present disclosure, through the gimbal arranged in the control grip, a spacecraft in a game can be controlled to do micro and precise motions upwards, downwards, leftwards, and rightwards with the hand and the forearm without changing throttle control position.
