Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle designs face challenges in improving travel stability, avoiding battery heat source concentration, and facilitating battery mobilization due to the distributed arrangement of high-voltage and low-voltage electric components.
Innovation Solution
The electric vehicle features a distributed arrangement of batteries to the right and left below the seat, with detachable battery support parts, a propeller shaft layout, and an electric motor positioned between the seat and the second battery, enhancing stability, heat dissipation, and facilitating battery attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If batteries are arranged in a distributed manner to right and left below the seat, then travel stability is improved and heat radiation is dispersed, but battery capacity expansion becomes more complex
Solution Approach 1:
The battery system is segmented into multiple individual batteries (first battery, second battery, third battery, fourth battery) arranged in a distributed manner to the right and left below the seat. This segmentation allows each battery to be independently positioned to optimize stability and heat dissipation while maintaining overall system functionality.
Solution Approach 2:
The batteries are arranged in a three-dimensional distributed configuration below the seat, utilizing vertical and lateral spaces. This dimensional arrangement improves travel stability by distributing mass across multiple locations and disperses heat radiation through spatial separation, while the modular support structure manages the complexity.
2Temperature
If batteries are arranged in a distributed manner to right and left below the seat, then heat radiation is dispersed, but battery attachment and detachment becomes more difficult
Solution Approach 1:
The battery system is divided into separate modular units (first, second, third, and fourth batteries) that can be independently attached and detached. Each battery has its own support structure, allowing individual handling without requiring manipulation of the entire battery system.
Solution Approach 2:
Battery support parts are pre-installed on the vehicle body at the appropriate positions before battery installation. These support parts include positioning features and attachment mechanisms that guide and facilitate the battery installation process, making it easier to attach and detach batteries in the distributed arrangement.
3Quantity of substance
If battery capacity is increased, then energy storage is improved, but vehicle weight increases
Solution Approach 1:
The battery system uses multiple smaller battery units (first, second, third, fourth batteries) arranged in a distributed manner, allowing flexible configuration to achieve the desired total capacity. This segmentation enables optimization of weight distribution and vehicle balance while meeting energy storage requirements.
Solution Approach 2:
The battery system is designed to be dynamic and adaptable, with batteries that can be attached and detached as needed. This allows the vehicle to adjust its weight and capacity configuration based on operational requirements, optimizing the balance between energy storage and vehicle weight.
4Object-affected harmful factors
If electric components are arranged in a distributed manner, then heat source concentration is avoided, but system complexity increases
Solution Approach 1:
The battery system is segmented into multiple spatially separated units (first, second, third, fourth batteries) positioned at different locations below the seat. This segmentation naturally disperses heat sources throughout the vehicle structure, avoiding heat concentration while the modular architecture manages system complexity.
