Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle operation input devices can unintentionally display information to occupants, leading to annoyance when fingers accidentally touch or approach steering switch portions, causing unnecessary emphasis displays.

Innovation Solution

A vehicle operation input device with a processor that only displays information and enables input operations when a specific intentional operation is performed on a state switching section, preventing accidental displays by maintaining an input disabled state unless the occupant intentionally activates the input section.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display section performs emphasis display when a finger touches or approaches the steering switch portion, then the function assigned to the portion is highlighted, but the occupant may feel annoyed due to unintentional activation

Engineering Contradiction:

Improveease of operationVSAvoidannoyance to occupant

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent applies dynamics by transitioning the input section between different operational states (input disabled state and input enabled state). The system dynamically adjusts its responsiveness based on the detected operation type, performing detailed detection only when a specific operation is confirmed, thereby avoiding unnecessary emphasis displays for accidental touches while maintaining ease of operation for intentional inputs.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by first detecting whether a specific operation has been performed before enabling detailed detection and emphasis display. This preliminary detection step filters out accidental touches, and only when a valid specific operation is confirmed does the system proceed to perform detailed detection and activate the emphasis display, thus preventing unwanted activations.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If the system performs detailed detection of input operations, then accurate input recognition is achieved, but unnecessary detection is performed when information is not being displayed

Engineering Contradiction:

Improveinput detection accuracyVSAvoidprocessing energy

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The system dynamically adjusts its detection behavior based on the current operational state. When in the input disabled state, detailed detection is suspended. When in the input enabled state, detailed detection is activated. This dynamic adjustment ensures accurate input recognition when needed while conserving processing energy during periods when information is not displayed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs a preliminary check to determine whether information is currently being displayed before activating detailed detection. This preliminary condition check prevents unnecessary detailed detection from occurring, thereby reducing processing energy consumption while maintaining accurate input detection when information is actively displayed.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If the input section is always in input enabled state, then all input operations are receivable, but accidental touches are more likely to trigger displays

Engineering Contradiction:

Improveinput reception capabilityVSAvoidaccidental activation

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The input section's operational state is dynamically switched between input disabled state and input enabled state based on the type of operation detected. This dynamic state management allows the system to maintain high adaptability for receiving intended inputs while reducing accidental activations by disabling input reception during periods when information is not actively displayed or when no specific operation is detected.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system performs preliminary detection to identify specific operations before enabling the input enabled state. This preliminary action filters out accidental touches, ensuring that the input section only becomes fully receptive to all input operations after a valid specific operation has been confirmed, thereby maintaining versatility while preventing accidental activation.

Inventive Principle:

Principle #10Preliminary action

AI summary

When an occupant has performed a specific operation that is an operation different to an input operation on a state switching section while in a state in which a display section capable of displaying information related to an input section is not displaying the information, a processor causes the information to be displayed on the display section and places the input section in an input enabled state in which the input operation is receivable. Moreover, when the occupant has not performed the specific operation on the state switching section while in state in which the information is not being displayed on the display section, the processor does not cause the information to be displayed on the display section.
