Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple acceleration sensors are used to detect motion in different directions, then the measurement precision and information quality improve, but the device complexity increases

Engineering Contradiction:
Improvemotion detection precisionVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple acceleration sensors (first and second acceleration sensors) into a single controller unit, merging their functions to detect motion in different directions simultaneously. This integration approach maintains high measurement precision while managing device complexity by consolidating sensor operations within one controller.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller is designed to perform multiple functions using the plurality of acceleration sensors, including detecting inclination angles, detecting motion directions, and distinguishing between different types of motions (swinging, shaking, tilting). This multi-functionality allows the system to extract comprehensive motion information from multiple sensors without proportionally increasing complexity.

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

2Ease of operation

If the motions of both hands are fixed in the game control, then the device complexity is reduced, but the ease of operation and player freedom are limited

Engineering Contradiction:
Improveplayer freedom of motionVSAvoidcontrol system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements dynamic game control where the controller responds to various types of motions (swinging, shaking, tilting) detected by the acceleration sensors. The game control unit dynamically adjusts the game object's behavior based on the type and direction of motion detected, allowing players freedom to move their hands in different ways while maintaining manageable control system complexity through automated motion classification.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes control parameters based on the type of motion detected. By identifying whether the motion is swinging, shaking, or tilting, and determining the direction and intensity of each motion type, the game control unit adjusts game parameters accordingly. This allows diverse player movements to be translated into meaningful game actions without requiring complex control mechanisms for each possible movement type.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If separate inputs from two acceleration sensors are used independently, then the device complexity is reduced, but the entertainment value and effectiveness of multi-directional motion detection are lost

Engineering Contradiction:
Improvemulti-directional motion utilizationVSAvoidsensor integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The game control unit acts as an intermediary that receives data from multiple acceleration sensors and processes it to detect the type and direction of motion. This intermediary component synthesizes information from both sensors to identify swinging motions, shaking motions, and tilting motions, enabling effective utilization of multi-directional motion detection while managing integration complexity through centralized processing.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An inclination of a first unit is detected based on an output from a first acceleration sensor provided in a first unit of a controller, and an inclination of a second unit is detected based on an output from a second acceleration sensor provided in a second unit separate from the first unit. A difference between the inclinations of the first unit and the second unit is detected, and game control is performed using the detected difference . Thus, with a game apparatus using a plurality of acceleration sensors or a plurality of sensors capable of detecting a motion or a posture, a dynamic play is made possible with a high degree of freedom of motion and an intuitive motion input is realized.
