Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle and electric bicycle frames lack effective heat dissipation and protection from humidity, which can negatively impact battery performance and longevity, especially when used in varying environmental conditions.
Innovation Solution
The frame design incorporates multiple chamber units with ribbed partitions and strategically placed holes for fluid communication, allowing for efficient heat dissipation and protection from humidity by accommodating the battery pack within a structure that enhances rigidity and air flow, thereby maintaining battery performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the battery pack is accommodated in a solid frame structure, then structural integrity and rigidity are improved, but heat dissipation capability deteriorates
Solution Approach 1:
The frame is divided into multiple chamber units (first chamber unit, second chamber unit, third chamber unit) that are coupled together. These chambers create internal void spaces that allow air flow paths for heat dissipation while the overall frame structure maintains its rigidity and strength for supporting the battery pack.
Solution Approach 2:
Different regions of the frame are designed with different properties: the chamber walls and coupling structures provide structural strength, while the internal chamber spaces provide thermal management pathways. The frame units have localized features (chambers, openings) that optimize heat dissipation in specific areas without compromising overall structural integrity.
2Object-affected harmful factors
If the frame structure is made solid for protection, then protection from humidity is improved, but heat dissipation deteriorates
Solution Approach 1:
The frame is segmented into multiple chamber units with controlled openings and couplings. This segmentation allows the frame to provide protective enclosure against humidity while creating internal pathways for air flow and heat dissipation from the battery pack.
Solution Approach 2:
The chamber units act as intermediary structures between the battery pack and the external environment. They provide a protected internal environment that shields the battery from humidity while allowing thermal management through controlled air flow paths within the chamber structure.
3Temperature
If multiple chamber units are coupled to improve heat dissipation, then heat dissipation capability is improved, but device complexity increases
Solution Approach 1:
Multiple frame units (first, second, and third chamber units) are coupled together to form an integrated frame structure. This merging of multiple functional units creates effective heat dissipation pathways while consolidating the overall structure to manage complexity through modular assembly.
Solution Approach 2:
The frame units are designed as multi-functional components that simultaneously provide structural support, humidity protection, and heat dissipation pathways. This multi-functionality reduces the need for separate components, thereby managing overall device complexity while achieving multiple objectives.
