Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of vehicles suitable for teenagers to ride outdoors and off-road, particularly electric motorcycles that do not require a driver's license or vehicle registration.
Innovation Solution
An off-road electric motorcycle designed for teenagers, featuring a frame with divided installation sections for a battery pack, including a main and backup battery pack, a power management module for controlled discharge, and safety features like a speed control switch, allowing for different riding modes and power tool compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a battery pack is installed in the frame of the electric motorcycle, then the power supply capacity is improved, but the structural complexity increases
Solution Approach 1:
The frame is divided into multiple installation sections (first installation section and second installation section) that can independently accommodate battery packs. This segmentation allows the frame to handle power supply requirements without requiring a completely redesigned structure, thus improving battery capacity while controlling structural complexity.
Solution Approach 2:
The frame's installation sections are designed to be universally compatible with different battery pack configurations. The same frame structure can accommodate various battery pack sizes and arrangements, making the frame multi-functional and reducing the need for complex custom structures for each battery configuration.
2Duration of action of moving object
If multiple battery packs are installed for extended operation, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The power management system is segmented into a main battery pack and a backup battery pack, each with dedicated connection terminals. This segmentation allows independent management of each battery pack, simplifying the control logic compared to managing a single large battery system, while still enabling extended operation duration.
Solution Approach 2:
The connection terminals for the backup battery pack are pre-positioned and configured in advance within the frame structure. This preliminary arrangement allows for quick and simple connection when the backup battery pack is installed, reducing the complexity of the power management system while ensuring extended operation capability.
3Adaptability or versatility
If the battery pack installation section is divided into multiple sections, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The installation sections are designed as separate, modular units with standardized interfaces. This segmentation allows each section to be manufactured independently with standard precision requirements, then assembled together to achieve the desired adaptability. The modular design reduces the overall manufacturing precision requirements compared to a single integrated structure.
Solution Approach 2:
Multiple installation sections are combined through standardized connection interfaces that tolerate certain dimensional variations. The merging mechanism incorporates tolerance compensation features, allowing the sections to be assembled with standard manufacturing precision while still achieving the required adaptability for different battery pack configurations.
