Solution Overview

Problem

The existing electronic authentication systems for motorcycles face challenges in allowing easy access and insertion of an emergency release key into a key cylinder, which is designed to be secure and difficult to access for theft prevention, thereby complicating emergency starting operations.

Innovation Solution

A motorcycle design that incorporates a vehicle-side control unit for authentication, an ignition switch unit, a lock mechanism, and an emergency release mechanism with a rod-like grip emergency release key and a magnet key, where the keyhole is positioned oppositely to the insertion direction, and an insertion opening in the vehicle body cover allows access, even in a narrow space, with the emergency release key also serving as a battery cover and featuring a guide portion for the magnet key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the emergency releasing key cylinder is designed to be secure and difficult to access for theft prevention, then security is improved, but the insertability of the emergency release key deteriorates

Engineering Contradiction:
ImprovesecurityVSAvoidinsertability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The keyhole is positioned in the opposite direction to the insertion direction of the emergency release key. The magnet key is provided on the lateral side of the grip portion end, allowing the key to be inserted from a narrow space by approaching the keyhole laterally rather than from the front, thus resolving the contradiction between security and insertability

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The magnet key is positioned on the lateral side of the grip portion end, changing the insertion approach from a linear front-to-back motion to a lateral approach. This dimensional change allows the key to access the keyhole in narrow spaces where traditional front-to-back insertion would be difficult, while the keyhole remains positioned to maintain security

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If the keyhole is positioned in a direction opposed to the insertion direction, then the space for inserting the magnet key is reduced and access is easier, but the structure becomes more complex

Engineering Contradiction:
ImproveaccessVSAvoidstructure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The magnet key is integrated directly onto the lateral side of the grip portion end of the emergency release key, merging the key element with the grip structure. This eliminates the need for separate key components and simplifies the overall structure while enabling access through narrow spaces

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The emergency release key serves multiple functions: it acts as both the grip handle and the key element (magnet key) for operating the emergency release mechanism. This multi-functionality reduces the number of separate components needed, simplifying the structure while maintaining ease of access

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

3Ease of operation

If the emergency release key is made portable by storing it in the electronic key casing, then portability is improved, but the risk of loss or misplacement increases

Engineering Contradiction:
ImproveportabilityVSAvoidavailability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The emergency release key is stored within the electronic key casing, merging the emergency key with the regularly used electronic key. This ensures the emergency key is always carried with the user's main key, improving portability while reducing the risk of loss since it's integrated into an object the user already carries consistently

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A motorcycle includes an ignition switch unit that allows at least starting operation of an engine and unlocking operation of a handlebar by operation of an ignition knob after restriction of turning of the ignition knob by a lock mechanism is canceled when electronic authentication is conducted. An emergency release mechanism is configured to directly or indirectly allow the starting operation of the engine by an emergency release key regardless of the electronic authentication. The emergency release key has a rod-like grip portion, and a magnet key provided to a lateral on a side of an end of the grip portion. A keyhole for the magnet key of the emergency release mechanism is arranged in a direction opposed to an insertion direction of the emergency release key.
