Solution Overview

Problem

Existing mouse devices struggle to accurately control the cursor in a straight line, especially in applications like drafting and first-person shooting games, leading to user fatigue due to the difficulty in maintaining precise movement.

Innovation Solution

A mouse device and interactive system with an angle snapping function, featuring a detection switch and control chip that allow users to quickly enter or leave angle snap mode, select snap angles, and automatically adjust based on velocity and acceleration, enabling smoother locus control without requiring graphic interface interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the user manually controls the mouse device to move in a straight line, then the cursor or aiming location can be controlled to move along a specific straight line, but it is difficult to control exactly and the user gets tired easily

Engineering Contradiction:
Improvecursor control precisionVSAvoiduser fatigue
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system automatically snaps the cursor to predetermined angles based on mouse movement direction, eliminating the need for users to manually control the cursor along precise straight lines. The angle snap function self-corrects the cursor path by detecting movement direction and adjusting to the nearest snap angle, thereby maintaining precision while reducing user effort and fatigue.

Inventive Principle:
Principle #25Self-service

2Reliability

If the user switches between angle snap mode and non-snap mode through graphic interface interactions, then the angle snap function can be enabled or disabled, but the switching process is time-consuming and reduces operational efficiency

Engineering Contradiction:
Improveangle snap mode switchingVSAvoidmode switching time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces graphic interface interactions with a detection switch (physical or electronic button) on the mouse device for mode switching. This mechanical/electronic substitution eliminates the need for users to navigate through software menus and icons, enabling instant mode switching directly from the mouse device and significantly reducing the time required to enable or disable angle snap functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The detection switch acts as an intermediary component between the user and the angle snap mode control. By placing this switch on the mouse device, it serves as a direct communication medium that instantly transmits the user's mode selection intent to the control chip, bypassing the need for graphic interface interactions and reducing switching time.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple snap angles are available for selection, then the system can adapt to different application requirements, but the complexity of selecting and changing snap angles increases

Engineering Contradiction:
Improvesnap angle selectionVSAvoidsnap angle change operation
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements periodic snap angle selection through repeated detection switch operations. Each press of the detection switch cycles through predetermined snap angles in sequence (e.g., 0°, 45°, 90°, 135°), allowing users to select different angles through simple repetitive actions rather than navigating complex menus or performing multiple configuration steps.

Inventive Principle:
Principle #19Periodic action
