Resin Electrical Component Box for Straddle Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Saddle-type vehicles face challenges in protecting electrical components from mud and other debris when traveling off-road, leading to potential damage and interference with their functionality.
Innovation Solution
The design incorporates an electrical component box made of resin, housing a bank angle sensor and other components, strategically positioned near the battery and start magnet switch, with features like protrusions for guiding wire harnesses and ribs for securing wire harnesses, which helps to prevent mud and debris from affecting the electrical components and improves wiring efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical components are placed separately without a protective housing, then wiring complexity increases and accessibility improves, but the components become vulnerable to mud and debris during off-road travel
Solution Approach 1:
The patent combines multiple electrical components (battery, electrical components, mounting portions) into a single integrated electrical component box. This merging approach protects all components from mud and debris while simplifying the overall wiring structure by consolidating connections within the enclosed box, directly resolving the contradiction between protection and wiring complexity
Solution Approach 2:
The electrical component box serves multiple functions simultaneously: it provides structural housing for components, offers protection from environmental contaminants, and acts as a mounting structure with integrated mounting portions. This multi-functionality eliminates the need for separate protective housings and mounting brackets, reducing overall device complexity while maintaining reliability
2Reliability
If electrical components are housed in a protective enclosure, then protection from mud and debris improves, but accessibility for maintenance and heat dissipation may be compromised
Solution Approach 1:
The electrical component box is designed as a separable structure with a removable cover that divides the housing into accessible sections. This segmentation allows the cover to be removed for maintenance access to electrical components while the main body remains protected, resolving the contradiction between enclosure protection and maintenance accessibility
Solution Approach 2:
The box incorporates pre-designed access points, mounting portions, and structured layouts that anticipate future maintenance needs. These preliminary design features enable quick access to specific components without requiring complete disassembly, maintaining ease of operation while preserving protective enclosure benefits
3Reliability
If multiple electrical components are consolidated in one box, then protection and wiring efficiency improve, but internal space arrangement becomes more complex
Solution Approach 1:
The electrical component box incorporates locally optimized features including mounting portions positioned at specific locations for easy component installation, strategically placed access points for maintenance, and organized internal spacing for different component types. This local quality approach simplifies the internal arrangement by providing dedicated zones for each component function, reducing overall arrangement complexity while maintaining consolidation benefits
