Solution Overview

Problem

Conventional game controllers lack ergonomic design, leading to repetitive strain injuries and do not accommodate varying hand sizes, failing to mimic natural grip shapes like handles of weapons or tools, and often require both hands for operation.

Innovation Solution

A customizable game controller with ergonomic features, allowing one or two fingers to grasp and multiple fingers to manipulate controls, featuring adjustable index finger controls and interchangeable components to fit different hand sizes, and incorporating wireless communication for devices like drones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional game controllers are designed with standard shapes, then manufacturing is simple, but they cause repetitive strain injuries and do not fit different hand sizes

Engineering Contradiction:
Improveergonomic comfortVSAvoidcontroller structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The controller employs interchangeable components including multiple grip sizes, trigger styles, and thumbstick configurations that can be swapped to match different user hand sizes and preferences. This dynamic adaptability allows the same base controller to serve multiple users with different ergonomic needs without requiring completely different controller designs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The controller is divided into modular segments that can be independently selected and assembled. Different grip modules, trigger modules, and thumbstick modules can be combined with a base controller unit, allowing users to customize the controller configuration to reduce strain on specific hand areas while maintaining structural simplicity through standardized connection interfaces.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If game controllers are designed to be manipulated by two hands, then control precision is improved, but ease of operation decreases for users with different hand sizes

Engineering Contradiction:
Improvecontrol precisionVSAvoidoperational ease
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The controller design places different control elements at specific locations optimized for different finger types. Thumbsticks are positioned for thumb access, while button arrays are arranged to be accessible by index, middle, and ring fingers. The interchangeable grip sizes ensure that each user's hand can naturally reach all controls without stretching or awkward positioning, maintaining precision while improving ease of operation.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If game controllers use fixed configurations, then manufacturing cost is reduced, but adaptability to different hand sizes is limited

Engineering Contradiction:
Improvehand size accommodationVSAvoidmanufacturing simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The base controller unit is designed with universal mounting interfaces that can accommodate multiple types of grips, triggers, and thumbsticks. A single production line can manufacture the standardized base unit, while separate lines produce various interchangeable components. This approach maintains manufacturing efficiency through standardization while achieving high adaptability through component variety.

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

AI summary

A pair of ergonomic controllers each having a thumb-stick controls, and index finger, control, and a trigger. The pair of controllers can be used to control a virtual object or physical object such as a drone. The index finger analog sticks and the triggers are configured to be floating such that they be adjustable for individual users and to force the user to grip each controller in a different hand using one or both of a pinky finger and a ring finger. The configuration of each controller enables an open thumb, index and middle finger for operations and a closed ring finger and pinky finger to hold each of the controllers. Use of the separate finger analog sticks enables aiming simultaneously at different objects or control of a cutting member or some other controls. The index finger analog sticks also can be moved backwards towards the controller for z-axis object control.
