Solution Overview

Problem

Conventional electrical component mounting structures for saddled vehicles do not adequately protect components from external factors like water, flying stones, and third-party access, and lack the ability to concentrate multiple components effectively near the vehicle body center.

Innovation Solution

An electrical component mounting structure that includes a case member with a lower and upper case, a sensor storage part with a container and lid, a rear cushion for vibration absorption, and a fuel tank for protection, which places control devices and sensors in a protected position near the vehicle body center, eliminating the need for dedicated stays and reducing component count.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If electrical components are mounted on dedicated stays, then components can be positioned, but the number of components increases and protection from external factors is insufficient

Engineering Contradiction:

Improveprotection from water, flying stones, and accessVSAvoidnumber of components

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent combines multiple electrical components (ABS modulator, inertial sensor, and other control devices) into a single integrated case member structure. This consolidation eliminates the need for separate dedicated stays for each component, reducing the overall number of parts while providing unified protection against external factors such as water, flying stones, and unauthorized access.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The case member serves multiple functions simultaneously: it houses and protects multiple electrical components, provides structural mounting without requiring separate stays, and offers environmental protection against water and debris. This multi-functional design reduces component count while enhancing protection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Quantity of substance

If components are concentrated near the vehicle body center, then mass concentration is achieved, but protection from external factors is reduced

Engineering Contradiction:

Improveconcentration of electrical componentsVSAvoidexposure to water, flying stones, and access

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

By consolidating multiple components into a single case member located near the vehicle body center, the patent achieves mass concentration while the enclosed case structure provides protective barriers against external factors, resolving the contradiction between concentration and protection.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The case member acts as an enclosing shell that protects concentrated electrical components from external factors. This shell structure allows components to be positioned centrally while maintaining protection from water, flying stones, and unauthorized access.

Inventive Principle:

Principle #30Flexible shells and thin films

3Object-affected harmful factors

If components are exposed to the outside, then access and heat dissipation are improved, but protection from external factors is insufficient

Engineering Contradiction:

Improveprotection from water, flying stones, and accessVSAvoidheat dissipation and access

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The case member provides an enclosing shell that protects components while incorporating designed openings and ventilation structures. These features allow controlled heat dissipation and maintenance access while maintaining protection from water, flying stones, and unauthorized access during normal operation.

Inventive Principle:

Principle #30Flexible shells and thin films
