Solution Overview

Problem

Accidental triggering of remote control keys in automobiles can lead to unintended functions being enabled, such as unlocking or opening the tailgate, due to accidental presses, which may result in property theft.

Innovation Solution

A control method that receives press signals from the remote control button, determines the number of press signals, and selectively enables functions based on these signals, including requiring two consecutive presses within a specific time interval to confirm intended operation, thereby reducing the likelihood of accidental triggering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single press on the remote control key enables a function, then the operation is simple and responsive, but the risk of accidental triggering increases

Engineering Contradiction:
Improveoperation simplicityVSAvoidaccidental triggering risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of press signal patterns before executing the function. By analyzing whether multiple presses occurred within a predetermined time interval, the system validates user intent before triggering the remote control function, thus preventing accidental activation while maintaining operational simplicity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system incorporates feedback by monitoring and counting press signals within a specific time window. This feedback mechanism allows the system to distinguish between intentional single presses and accidental multiple presses, enabling reliable function activation only when the press pattern matches the expected single-press pattern

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the remote control key has a bold and smart design, then the aesthetics and user experience are improved, but the hardware structure cannot avoid the risk of accidental button presses

Engineering Contradiction:
Improvedesign flexibilityVSAvoidaccidental press risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical prevention methods (such as physical button protection structures) with an electronic/software-based solution. By using press signal counting and time interval detection algorithms, the system eliminates the need for complex mechanical protection structures, allowing bold and smart key designs while preventing accidental presses through intelligent signal analysis

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

3Reliability

If multiple press signals are required to enable a function, then accidental triggering is reduced, but the operation becomes more complex

Engineering Contradiction:
Improveaccidental triggering preventionVSAvoidoperation complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system uses partial action by requiring only a specific pattern of presses (one or two presses within a time interval) rather than multiple distinct operations. This partial requirement is sufficient to prevent accidents while maintaining ease of operation, as the additional press requirement is minimal and intuitive for users

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The invention pertains to the technical field of automobiles, and particularly provides a control method for preventing accidental triggering of a remote control key of an automobile, and an automobile. The invention is to solve the problem of a corresponding function being triggered due to an accidental press on an existing remote control key of an automobile. To this end, the remote control key of the automobile according to the invention includes a remote control button, where the control method includes: receiving a press signal from the remote control button; determining the number of press signals; and selectively enabling a function of a remote control instruction of the automobile based on the number of press signals. The invention does not rely on a hardware design, but uses a software-based strategy to prevent a corresponding function of a remote control instruction from being enabled when an accidental press on the remote control key button of the automobile is caused by a styling design of the automobile key, etc. This lowers a requirement on a hardware structural design of the remote control key, so that the styling design of the remote control key is more flexible.
