Solution Overview

Problem

Existing vehicle controllers struggle to provide an in-vehicle environment that aligns with a user's deeper latent consciousness, beyond apparent satisfaction, due to the inability to grasp and address underlying physical conditions such as strain, fatigue, and stress.

Innovation Solution

A vehicle controller that determines a user's consciousness level through kinesiology tests, using muscle responses to external stimuli, and adjusts vehicle interfaces like air conditioning, lighting, and fragrance to optimize the in-vehicle environment based on the user's latent needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional biological information measurement is used, then apparent consciousness can be grasped, but deeper latent consciousness cannot be detected

Engineering Contradiction:
Improveconsciousness detection depthVSAvoidlatent consciousness measurement
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces muscle response as an intermediary indicator to indirectly measure latent consciousness. Instead of directly measuring consciousness, the system measures muscle strength changes in response to stimuli, which serve as a mediator reflecting the user's deeper psychological state and latent needs.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces conventional biological measurement methods (electrical, chemical, or optical sensors) with a mechanical measurement approach. By using a force sensor to measure grip strength changes during kinesiology tests, the system substitutes traditional biological information detection with mechanical force measurement to access deeper consciousness levels.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If the in-vehicle environment is adjusted based on apparent satisfaction, then basic comfort is provided, but latent physical conditions like strain and fatigue are not addressed

Engineering Contradiction:
Improveenvironment adaptation depthVSAvoidlatent physical condition information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the system continuously monitors muscle response through grip strength measurements and uses this information to adjust the in-vehicle environment. The feedback loop enables the system to detect changes in latent physical conditions and respond by optimizing environmental parameters such as temperature, humidity, and air quality.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary kinesiology tests to detect latent physical conditions before they manifest as apparent discomfort. By measuring grip strength and muscle response in advance, the system can proactively adjust the in-vehicle environment to prevent strain and fatigue from developing, rather than merely reacting to visible symptoms.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If general in-vehicle environment control is used, then basic functionality is provided, but user-specific latent needs are not met

Engineering Contradiction:
Improveuser satisfactionVSAvoidconsciousness-based control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent enables the system to automatically detect user needs and adjust the environment without requiring explicit user input or complex interactions. The kinesiology test and muscle response measurement allow the system to self-determine the user's latent needs and autonomously optimize environmental parameters, simplifying the user experience while maintaining high adaptability.

Inventive Principle:
Principle #25Self-service

AI summary

A vehicle controller includes a processor, which acquires biological data of a user of a vehicle from a sensor provided in the vehicle; determines a consciousness level of the user based on the biological by conducting a kinesiology test; and controls an interface mounted on the vehicle in accordance with the determined consciousness level to change an in-vehicle environment.
