Kick Starter Generator Authentication for Saddled Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles with discharged or non-equipped batteries, the control device cannot be activated to authenticate the FOB key signal, requiring two kick operations to start the engine, and there's a risk of unauthorized engine startup.
Innovation Solution
An authentication device that uses a generator powered by the kick starter to supply electricity to the control unit, allowing engine startup with authentication of the FOB key signal in one operation, and includes a locking mechanism to ensure the ignition switch is only released when authenticated, with predetermined time settings to manage engine operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the control device is activated before engine startup to authenticate the FOB key signal, then the engine can be started by one kick operation, but the control device cannot be activated in vehicles with discharged or non-equipped batteries
Solution Approach 1:
The system performs preliminary authentication of the FOB key signal during the kick operation itself, before full engine startup. The control device is activated temporarily during the kick operation to authenticate the signal, and if authentication succeeds, the engine is permitted to start. This eliminates the need for a separate pre-startup authentication phase while ensuring security.
2Ease of operation
If permission to start the engine is given without operating the ignition switch to enable one kick operation startup, then engine startup is completed by one operation, but unauthorized persons can also start the engine
Solution Approach 1:
The system incorporates feedback mechanisms where the control device continuously monitors authentication status and ignition switch state. After successful FOB key authentication, the system provides feedback by enabling engine startup only if the ignition switch is in the appropriate position. This feedback loop ensures that both authentication and ignition switch operation are required, preventing unauthorized startup while enabling one-kick operation for authorized users.
3Productivity
If the engine is started without authentication to allow one kick operation, then startup is simplified, but security against unauthorized access is compromised
Solution Approach 1:
The system merges the authentication process with the engine startup process itself. The FOB key authentication, control device activation, and engine startup permission are combined into a single integrated sequence triggered by the kick operation. This merging eliminates separate authentication steps that would slow down startup, while maintaining security through the integrated authentication check during the kick operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables engine startup by one kick operation for the FOB key owner, prevents unauthorized startup, and reduces fuel consumption by stopping the engine if the ignition switch is not turned on promptly after authentication.
Implementation Method 1
a generator (50) that rotates in conjunction with an operation on the kick starter (14) is configured such that, due to operating the kick starter (14), electric power generated by the generator (50) is supplied to the control unit (30)
