Solution Overview

Problem

Current game controllers for FPP, FPS, and RPG games are ergonomically inadequate, leading to discomfort and wrist disorders due to the need for complex finger movements and prolonged use, as they fail to accurately replace the keyboard's W, A, S, D buttons and often require simultaneous mouse operation, resulting in slower response times and fatigue.

Innovation Solution

A 'plug and play' computer game controller with a stable, ergonomic design featuring a sliding lever mechanism and programmable buttons that can be used wirelessly, allowing for precise character movement without requiring the player to constantly adjust hand position, thereby reducing strain on hand joints and improving accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a game controller replaces the keyboard's W, A, S, D buttons using a trackball or joystick, then the controller can be operated with both hands, but the movement accuracy decreases and response time increases compared to direct keyboard use

Engineering Contradiction:
Improvetwo-handed operation capabilityVSAvoidcharacter movement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The controller is divided into distinct functional zones: a stable base for wrist support, a chassis with directional buttons for precise character movement, and separate action buttons. This segmentation allows each zone to optimize its function - the base provides stability while the button layout enables accurate input

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The controller transitions from requiring hand movement (trackball/joystick) to allowing static hand placement with finger-based input. The sliding lever mechanism adds a new dimension of wrist-based control, separating hand positioning from movement direction selection

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If additional function keys are added to the controller to increase game functionality, then more character options can be controlled, but the complexity of finger movements increases and response time decreases

Engineering Contradiction:
Improvecharacter control functionalityVSAvoidresponse time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The controller uses programmable buttons that can be assigned to different functions depending on the game or character being controlled. This allows a fixed number of physical buttons to provide variable functionality, increasing adaptability without adding more buttons that would complicate operation

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller allows users to program and customize button functions according to their specific needs and preferences. This self-programming capability enables optimization of control layouts for different game scenarios without requiring additional physical controls

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the controller is designed to be held in hands during use, then portability is improved, but palm support is lost causing fatigue during prolonged use

Engineering Contradiction:
ImproveportabilityVSAvoidprolonged use comfort
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The controller base is designed to replicate the stable surface function of a keyboard, providing a flat, supportive area for the palm and wrist. This copying of the keyboard's stabilizing function allows prolonged use without fatigue, while the overall portable form factor maintains ease of transport

Inventive Principle:
Principle #26Copying

4Reliability

If the controller replaces only part of the keyboard functionality, then keyboard ergonomics are maintained, but the need for simultaneous mouse operation remains causing slower response times

Engineering Contradiction:
Improveergonomic supportVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The controller merges multiple input functions into a single device: directional control, action buttons, and programmable functions all in one unit. This eliminates the need to switch between keyboard and mouse, unifying control and improving response time while maintaining ergonomic benefits

Inventive Principle:
Principle #5Merging (Combining)
