Motorcycle Immobilizer Amplifier Mounting for Heat Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing immobilizer amplifier mount structures for motorcycles are prone to malfunction due to high temperatures near the combustion engine and face challenges in obtaining stable mounting space, leading to complex and inefficient arrangements.
Innovation Solution
The immobilizer amplifier is mounted rearward of the cylinder head on the inner surface of the motorcycle frame's intermediate portion, separated from the ignition switch unit, using an amplifier bracket that shares fastening with the engine mount, facilitating heat protection and simplifying the mounting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the immobilizer amplifier is disposed in the front portion of the motorcycle body near the ignition switch, then wiring of signal lines is facilitated and cooling effect is obtained, but the immobilizer amplifier is exposed to high temperature from the combustion engine causing malfunction
Solution Approach 1:
The patent separates the immobilizer amplifier from the ignition switch unit, placing the amplifier in a different location (front fairing or side fairing) while maintaining the ignition switch in its original position. This segmentation allows the amplifier to be positioned for optimal cooling and wiring access while avoiding the high-temperature engine area.
Solution Approach 2:
The patent introduces an intermediary mounting structure (fairing or side fairing) that serves as a buffer zone between the ignition switch unit and the immobilizer amplifier. This intermediary location provides both thermal protection from the engine and convenient access for wiring and cooling airflow.
2Temperature
If the immobilizer amplifier is disposed in the front portion of the motorcycle body, then cooling effect is obtained by incoming wind, but the mounting space is difficult to obtain due to many components such as ignition switch and radiator
Solution Approach 1:
The patent utilizes the fairing or side fairing structure to serve multiple functions: it provides mounting space for the immobilizer amplifier, maintains the aerodynamic shape of the motorcycle body, and allows passage of cooling airflow. This multi-functional use of existing structural elements avoids adding separate mounting structures.
Solution Approach 2:
The patent transitions from a two-dimensional planar arrangement in the front fairing to a three-dimensional utilization of the side fairing space, mounting the amplifier on the inner surface of the side fairing. This dimensional change provides adequate mounting space while maintaining the compact front portion design.
3Volume of moving object
If the immobilizer amplifier is provided separately from the ignition switch unit, then the size of the ignition switch is reduced, but the mounting structure becomes complicated
Solution Approach 1:
The patent designs the fairing or side fairing structure to self-provide the mounting function for the immobilizer amplifier through its existing structural features. The amplifier is mounted on the inner surface of the fairing, which naturally provides both mounting support and protective enclosure, eliminating the need for separate complex mounting brackets or structures.

AI summary
A motorcycle immobilizer amplifier mount structure that allows arrangement in the front portion of a motorcycle body to be simplified while reducing the size of an ignition switch, and prevents an immobilizer amplifier (24) from being exposed to a high temperature of a combustion engine (E). In the immobilizer amplifier mount structure, immobilization signal output section (23) is incorporated in an ignition switch unit (SU), and the immobilizer amplifier (24) amplifies an immobilization signal from the immobilization signal output section (23), and is mounted rearward of a cylinder head (29) of the combustion engine (E) on an inner surface of an intermediate portion, in a longitudinal direction, in a pair of left and right frame pieces (1A, 1B) forming a part of a motorcycle frame structure (FR).
