Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If game controller joystick is used to control cursor, then cursor control function is achieved, but control flexibility and accuracy are insufficient

Engineering Contradiction:
Improvecursor control accuracyVSAvoidcontrol flexibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the cursor movement characteristics adjustable through different response speed profiles. The system can dynamically change the relationship between joystick input and cursor output based on game requirements, allowing flexible control of cursor acceleration, deceleration, and response timing to achieve both precision and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes parameters by implementing multiple response speed profiles that modify the transfer function characteristics. By adjusting parameters such as response speed, acceleration rate, and deceleration rate, the system optimizes the mapping between joystick movements and cursor movements to achieve precise control under different gaming scenarios.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If conventional joystick control is used, then simple control mechanism is maintained, but cursor movement speed and accuracy are inconsistent

Engineering Contradiction:
Improvecursor movement accuracyVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary processing layer between the joystick input and cursor output. This intermediary system includes response speed profiles and transfer functions that mediate the signal transformation, enabling precise cursor control without requiring complex hardware modifications to the joystick itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the control mechanism into distinct functional components: joystick input acquisition, response speed profile selection, transfer function processing, and cursor output generation. This segmentation allows each component to be optimized independently while maintaining overall system precision without excessive complexity.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If fixed response speed profile is used, then system simplicity is maintained, but adaptability to different gaming scenarios is limited

Engineering Contradiction:
Improvecontrol adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamics through the ability to switch between multiple response speed profiles based on gaming scenarios. The system can dynamically adapt the cursor control characteristics to match different game requirements, such as precision-oriented games versus speed-oriented games, thereby enhancing versatility without requiring a completely complex redesign.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses parameter changes by implementing a selectable response speed profile mechanism. Different profiles adjust key parameters like response time, acceleration, and deceleration rates, allowing the system to adapt to various gaming scenarios by simply changing parameters rather than redesigning the entire control architecture.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method and apparatus for controlling a cursor control, and a related device. The method comprises: acquiring, from a target handle, a real offset value of a target operating rod in an operating rod coordinate system, wherein the target handle is used for controlling a target cursor control in a target device (S1); according to the real offset value, determining a simulated offset value, at a first moment, of the target operating rod in the operating rod coordinate system (S2); according to the simulated offset value at the first moment, determining a first position, at the first moment, of the target cursor control in a target device coordinate system (S3); and sending the first position to the target device, so as to control the target cursor control to move from a second position, at a second moment, in the target device coordinate system to the first position, wherein the second moment is a moment before the first moment, and the speed of movement of the target cursor control moving from the second position to the first position is positively correlated with the magnitude of the simulated offset value at the first moment (S4).
