Solution Overview

Problem

Existing remote control systems for motor vehicles face challenges in securely and efficiently registering identification codes, as they can inadvertently transition to registration mode due to user operations, leading to increased complexity and potential errors.

Innovation Solution

A method involving a registration-dedicated harness that connects between the remote control receiving unit and the vehicle's harness, allowing the remote control receiving unit to transition to a registration mode, enabling secure and simple identification code registration by generating and storing identification codes in a registration memory, with automatic mode ending based on code count or time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lock controller is put in registration mode by performing predetermined operations on multiple switches, then portable unit ID registration can be changed or added, but inadvertent registration may occur when users perform corresponding operations by chance

Engineering Contradiction:

Improveportable unit ID registration capabilityVSAvoidinadvertent registration prevention

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A registration-dedicated harness is introduced as an intermediary component between the existing harness and the remote control receiving unit. This harness contains a switch that acts as a mediator to activate registration mode, separating the registration function from ordinary user operations. The registration-dedicated harness serves as a physical intermediary that prevents inadvertent activation while enabling controlled registration by workers.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the predetermined operation of multiple switches is made sufficiently complicated to prevent inadvertent registration, then security is improved, but the operation that workers must perform becomes complicated and man-hours increase

Engineering Contradiction:

Improveinadvertent registration preventionVSAvoidworker operation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The registration activation function is segmented from the ordinary control switch operations. Instead of requiring complicated sequences of multiple switches, the system is divided such that the registration-dedicated harness with its dedicated switch handles registration activation separately. This segmentation allows workers to perform simple single-switch operations while maintaining security through the dedicated harness connection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The registration-dedicated harness acts as an intermediary that simplifies the worker's operation to a single switch press while maintaining security. The harness itself serves as a controlled interface that, when connected, enables the registration function through a simple operation, eliminating the need for complicated multi-switch sequences.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a registration-dedicated harness is connected between the harness and the remote control receiving unit, then inadvertent registration is prevented and worker workload is reduced, but an additional harness component is required

Engineering Contradiction:

Improveinadvertent registration preventionVSAvoidharness structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The registration-dedicated harness is designed to be connected to the existing harness structure, utilizing the existing electrical connections and communication protocols. By making the system multi-functional, the same harness infrastructure serves both ordinary control operations and registration functions, minimizing the need for entirely separate wiring while still providing the security benefits of a dedicated registration interface.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The method registers a remote control unit (40) into a remote control receiving unit (36) connected via a harness (110) to a device (50) installed in a vehicle body (2). The method includes a step of connecting a registration-dedicated harness (120) between the harness (110) and the remote control receiving unit (36) and making the remote control receiving unit (36) transition to a registration mode, and a step of making an identification code be generated from the remote control unit (40) and making the identification code be received by the remote control receiving unit (36) in the registration mode to register the identification code, received by the remote control receiving unit (36), into a registration memory (107M).
