Solution Overview

Problem

Straddled vehicles face challenges in maintaining a compact size while ensuring effective wireless communication with mobile devices due to limited space and potential interference from stored luggage, leading to compromised communication quality.

Innovation Solution

The straddled vehicle design incorporates a communication unit compartment located between the hinge and storage box, above the battery compartment, which also serves as a lid for the battery compartment, allowing for compact placement and minimizing interference from the seat and luggage, thus maintaining a smaller vehicle size and improving communication quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the communication unit is mounted on the straddled vehicle, then wireless communication functionality is added, but the vehicle size increases

Engineering Contradiction:

Improvewireless communication functionalityVSAvoidvehicle size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The communication unit compartment is nested within the existing vehicle structure by utilizing the space between the hinge and storage box, and above the battery compartment. This allows the communication unit to be integrated into the vehicle without requiring additional external space, thereby adding wireless communication functionality while maintaining compact vehicle dimensions.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the communication unit is positioned to mount on the vehicle, then communication functionality is achieved, but communication quality with mobile device in storage pocket deteriorates

Engineering Contradiction:

Improvecommunication functionalityVSAvoidcommunication quality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The communication unit is positioned in a specific location (between the hinge and storage box, above the battery compartment) that is optimized for communication quality. This location minimizes interference with the mobile device stored in the storage pocket while maintaining compact vehicle dimensions, thereby achieving both communication functionality and high communication quality.

Inventive Principle:

Principle #3Local quality

3Volume of moving object

If the communication unit is arranged in the storage box, then space utilization is improved, but communication is obstructed by luggage

Engineering Contradiction:

Improvespace utilizationVSAvoidcommunication quality

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The communication unit is extracted from the storage box and placed in a separate compartment between the hinge and storage box. This separation ensures that the communication unit is not obstructed by luggage stored in the storage box, while still utilizing the available internal space efficiently. The communication unit maintains its functionality without interference from stored items.

Inventive Principle:

Principle #2Taking out (Extraction)
