Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid saddle-type vehicles face challenges in transitioning to pure electric vehicles due to increased weight, limited space for additional batteries, and structural modifications, leading to complexity and cost, while maintaining dynamic stability and ride quality.
Innovation Solution
A modular energy storage system is integrated into the vehicle's swing arm, allowing removable mounting of auxiliary energy storage devices without altering the existing hybrid layout, utilizing a hub motor for direct wheel drive and regenerative braking to recharge batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If additional batteries are mounted in limited vehicle space, then traveling distance is extended, but structural challenges and manufacturing complexity increase
Solution Approach 1:
The swing arm is designed with a universal mounting interface that serves dual purposes: supporting the rear wheel and providing mounting capability for auxiliary energy storage devices. This multi-functional design allows the same structural component to fulfill multiple roles without adding separate mounting structures, thereby extending traveling distance while avoiding increased structural complexity.
2Duration of action of moving object
If hybrid vehicle configuration with both internal combustion engine and electric motor is used, then long travel capability is achieved, but vehicle weight and system complexity increase
Solution Approach 1:
The vehicle powertrain configuration is made dynamic and adaptable through the removable auxiliary battery system. The vehicle can operate in different modes (single battery electric mode, hybrid mode with both engines and batteries, or extended range mode with all power sources) depending on the presence and configuration of the auxiliary energy storage device, allowing optimization of weight versus travel capability based on specific operational needs.
3Adaptability or versatility
If manufacturer produces vehicles with multiple technology types simultaneously, then market coverage is improved, but production complexity and manufacturing cost increase
Solution Approach 1:
The swing arm mounting interface provides a universal platform that accommodates multiple powertrain configurations (internal combustion engine only, electric motor only, hybrid, or various battery configurations). This universal design allows the same base vehicle platform to be produced in different technology variants without requiring separate dedicated mounting structures for each powertrain type, thereby reducing production complexity while maintaining market versatility.
4Loss of time
If conventional hybrid vehicle layout is retained during conversion to electric vehicle, then conversion time and cost are reduced, but space for energy storage devices is limited
Solution Approach 1:
The auxiliary energy storage devices are mounted on the swing arm, utilizing the vertical and lateral dimensions of the vehicle's rear suspension area rather than consuming horizontal floor space. This dimensional approach allows additional battery capacity to be integrated into the existing hybrid vehicle layout without requiring extensive structural modifications or sacrificing passenger/cargo space, thereby enabling quick conversion while accommodating adequate energy storage volume.
