E-Bike Frame Integrating Controller and Battery for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electrically-assisted vehicles are bulky, heavy, and complex in structure due to the need for additional installation space and external components for controllers and batteries, which hinders a concise design and increased functionality.
Innovation Solution
A frame design for electrically-assisted vehicles that integrates the controller into the middle tube and battery into the down tube, with internalized charging circuits, including USB, Bluetooth, GPS, and APP functionalities within a charging box, reducing weight and enhancing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If controller and battery are installed outside the frame with additional installation space and structure, then functionality is improved, but weight increases and design becomes un-concise
Solution Approach 1:
The patent merges the controller, battery, and charging box into the frame structure. The controller is installed in the middle tube, the battery is installed in the down tube, and the charging box is integrated into the frame, eliminating the need for separate external installation spaces and reducing overall vehicle weight while maintaining functionality.
Solution Approach 2:
The patent employs nesting by placing the controller inside the middle tube, the battery inside the down tube, and the charging box integrated into the frame structure. This nested arrangement maximizes space utilization within the frame while minimizing external components and weight.
2Adaptability or versatility
If controller and battery are installed outside the frame with additional installation space and structure, then functionality is improved, but design conciseness deteriorates
Solution Approach 1:
The patent merges all functional components (controller, battery, charging box) into the frame structure, creating a unified and concise design. The controller is positioned in the middle tube, the battery in the down tube, and the charging box integrated into the frame, eliminating protruding external components and achieving a sleek, concise appearance.
3Adaptability or versatility
If additional functional circuits are added outside the frame, then functionality is improved, but weight increases and design becomes un-concise
Solution Approach 1:
The patent merges additional functional circuits (USB charging, Bluetooth, GPS, APP) into the charging box that is already integrated into the frame. This eliminates the need for separate external installations for these functions, reducing weight and maintaining design conciseness while satisfying increasing functional needs.
Solution Approach 2:
The charging box is designed as a multi-functional unit that integrates USB charging, Bluetooth connectivity, GPS functionality, and APP communication. This universal design allows multiple functions to be achieved through a single integrated component rather than multiple separate external components, reducing weight and improving conciseness.
4Adaptability or versatility
If battery is installed outside the frame with separated installation space and structure, then functionality is improved, but weight increases and design becomes un-concise
Solution Approach 1:
The patent employs nesting by placing the battery inside the down tube of the frame. This integrated arrangement eliminates the need for separate external battery installation space, creating a concise and unified design while maintaining battery functionality.
