Solution Overview

Problem

Current handheld controllers lack dynamic adjustment capabilities to accommodate varying hand sizes and grips, leading to suboptimal user experiences in gaming and other interactive applications.

Innovation Solution

The handheld controller incorporates a touch sensor with capacitive pads that dynamically adjust and map to different fingers based on hand size and grip, using logic to associate touch sensor data with specific fingers and adapt to changing grip patterns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If static sensor assignment is used in handheld controllers, then device complexity is reduced, but adaptability to different hand sizes and grips deteriorates

Engineering Contradiction:
Improveadaptability to different hand sizes and gripsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic sensor assignment where the mapping between touch sensors and virtual controls is not fixed but changes based on detected grip patterns. The system continuously monitors sensor data to identify grip type and hand size, then dynamically reconfigures the control layout accordingly, allowing the controller to adapt to different users and grip styles without requiring multiple physical configurations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The controller automatically detects grip patterns and hand characteristics through its sensors and self-configures the control mapping without user intervention. The system performs self-calibration by analyzing touch sensor data to determine grip type and automatically adjusting the virtual control positions to match the detected hand geometry, eliminating the need for manual setup or calibration procedures

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If dynamic sensor assignment is implemented, then adaptability to different users is improved, but processing complexity increases

Engineering Contradiction:
Improveadaptability to different usersVSAvoidprocessing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system pre-defines multiple grip patterns and hand size categories during manufacturing, storing reference data for various user types. When a user grabs the controller, the system compares sensor readings against these pre-established patterns to quickly identify the user type and apply the corresponding configuration, avoiding the need for complex real-time calculations or machine learning algorithms

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors touch sensor data to detect grip patterns and provides feedback to the control mapping system. By analyzing the location and pressure distribution of touch points, the system determines grip type and hand size, then adjusts the virtual control positions accordingly, creating a closed-loop system that adapts to user characteristics through iterative sensor feedback

Inventive Principle:
Principle #23Feedback

3Ease of operation

If fixed control layout is used, then ease of manufacture is improved, but user experience quality deteriorates

Engineering Contradiction:
Improveuser experience qualityVSAvoidease of manufacture
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The controller uses a single, universal physical design that can serve multiple user types and grip styles. By implementing software-based dynamic mapping rather than physical reconfiguration, the same hardware platform can adapt to different hand sizes, grip patterns, and user preferences, eliminating the need for multiple specialized controller variants while maintaining ease of manufacture

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

Solution Approach 2:

The system changes the parameter mapping between physical sensors and virtual controls based on detected user characteristics. By modifying the software parameters that define control positions and sensor associations rather than changing physical hardware parameters, the system achieves customized user experiences while maintaining a standardized manufacturing process

Inventive Principle:
Principle #35Parameter changes
