Solution Overview

Problem

Existing gun-shaped controllers for videogames and VR systems lack realistic haptic feedback, particularly in transitioning between different in-game weapons, and current rumble-pack technologies are not sufficiently immersive.

Innovation Solution

A haptic feedback module incorporating a linear impact unit with a selectively attachable mass mechanism, using a linear solenoid to create varying recoil effects by adding or detaching additional masses based on in-game weapon changes, enhancing the haptic feedback experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed mass is used in the haptic feedback module, then the device complexity is reduced, but the adaptability to different in-game weapons is poor

Engineering Contradiction:
Improveadaptability to different in-game weaponsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mass configuration is made dynamic through a retention mechanism that can attach or detach additional masses based on the selected in-game weapon. The linear solenoid dynamically reconfigures the mass arrangement to match different weapon characteristics, enabling adaptability without permanent complex structural changes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The haptic feedback module is segmented into a base mass and detachable additional masses. This segmentation allows the system to reconfigure its total mass by attaching or removing individual mass components, providing versatility while keeping each individual component simple.

Inventive Principle:
Principle #1Segmentation

2Reliability

If additional masses are added to increase reaction force, then the haptic feedback realism is improved, but the device complexity increases

Engineering Contradiction:
Improvehaptic feedback realismVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The retention mechanism uses a linear solenoid to dynamically attach or detach additional masses based on the required reaction force for different weapons. This dynamic reconfiguration allows the system to optimize haptic feedback realism for each weapon type without requiring permanently complex multi-mass structures.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the mass parameter by selectively attaching or detaching additional masses to match the physical characteristics of different in-game weapons. This parameter adjustment enables realistic haptic feedback for each weapon type while maintaining a relatively simple base structure.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a complex mass retention mechanism is used, then the adaptability to different weapons is improved, but the ease of operation decreases

Engineering Contradiction:
Improveadaptability to different in-game weaponsVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The linear solenoid automatically attaches or detaches additional masses based on signals from the entertainment device indicating the selected weapon type. This self-service mechanism eliminates the need for manual intervention by the user to reconfigure the haptic feedback module, maintaining ease of operation while achieving high adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system receives feedback about the selected in-game weapon from the entertainment device and automatically reconfigures the mass arrangement accordingly. This closed-loop feedback mechanism ensures the haptic feedback module adapts to different weapons without requiring user awareness or manual adjustment.

Inventive Principle:
Principle #23Feedback
