Solution Overview

Problem

Incorporating modern electronic features into retro-style motorcycles poses a challenge due to the complexity of integrating wiring harnesses and fluid hoses while maintaining the vehicle's aesthetic appeal.

Innovation Solution

A motorcycle frame and configuration assembly that hides electronic components by routing wires and hoses through a hollow backbone frame member, using a tunnel design for the fuel tank and tray system to conceal fasteners, and strategically positioning electrical components to maintain the retro look.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If modern electronic features are incorporated into retro-style motorcycles, then functional capability is improved, but aesthetic appearance deteriorates due to visible wiring harnesses and electronic components

Engineering Contradiction:
Improvefunctional capabilityVSAvoidaesthetic appearance
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The patent extracts electronic components (battery, control modules, wiring) from their traditional exposed positions and relocates them into hidden compartments within the frame structure. The battery is positioned in a compartment formed by the frame rails, and wiring harnesses are routed through hollow sections of the frame members, effectively removing visible electronic elements from the motorcycle's exterior appearance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements nesting by placing electronic components within the hollow structural members of the frame. The battery is nested within a compartment formed by the frame rails, and wiring is nested within hollow frame sections. This nested arrangement allows modern electronics to be integrated without disrupting the retro aesthetic, as components are contained within the existing frame structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If wiring harnesses and electronic components are added to retro motorcycles, then modern functionality is improved, but device complexity increases

Engineering Contradiction:
Improvemodern functionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The frame structure serves multiple functions: it provides structural support for the motorcycle while simultaneously housing electronic components and routing wiring harnesses. The hollow frame members act as both structural elements and conduits for electrical wiring, reducing the need for separate wiring channels and simplifying the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the structural frame with the electrical system integration. The frame rails and members are designed to incorporate battery compartments and wiring channels, combining what would traditionally be separate systems (chassis and electrical) into a unified structure. This integration reduces the number of discrete components and simplifies installation.

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If electronic components are concealed to maintain retro styling, then aesthetic appearance is improved, but accessibility for maintenance deteriorates

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidcomponent accessibility
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The frame is segmented into modular sections with accessible openings or removable panels that allow technicians to reach electronic components without disassembling the entire frame. The battery compartment and wiring channels are positioned and configured to provide access points that maintain the retro aesthetic when closed but facilitate easy component removal and replacement during maintenance.

Inventive Principle:
Principle #1Segmentation
