Pedelec Frame with Internal Battery Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pedelec battery modules are inconveniently fixed behind the saddle member, affecting the appearance and unity of the pedelec, and are not easily detachable for storage.
Innovation Solution
A Y-shaped frame design with a receiving space and installed space between tubes allows for detachable battery module installation, keeping the battery module hidden from view and enabling easy detachment when not in use, using connectors and sliding mechanisms for secure electrical coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the battery module is fixed behind the saddle member, then the battery module is securely mounted, but the appearance unity of the pedelec is compromised and containment convenience is reduced
Solution Approach 1:
The battery module is extracted from the traditional fixed position behind the saddle member and relocated to a dedicated receiving space within the frame structure. This extraction allows the battery module to be hidden within the frame's internal space, maintaining the aesthetic unity of the pedelec's external appearance while providing secure containment through the frame's structural receiving space.
Solution Approach 2:
The battery module is nested within the frame body's receiving space, which is integrated into the frame's structural design. The receiving space is formed by the frame's tube structure, allowing the battery module to be contained within the frame's internal volume, thus maintaining appearance unity while providing secure mounting.
2Adaptability or versatility
If the battery module is fixed behind the saddle member, then the battery module is securely mounted, but detachability for storage is compromised
Solution Approach 1:
The mounting system is segmented into a fixed frame structure with a receiving space and a detachable battery module. The battery module can be independently attached and detached from the frame, allowing for flexible storage options while maintaining secure mounting during use through the frame's structural receiving space and connector system.
Solution Approach 2:
The mounting system transitions from a static fixed mounting to a dynamic detachable mounting system. The battery module can be attached when needed and detached for storage, providing adaptability while maintaining secure mounting during operation through the frame's structural receiving space and electrical connector system.
3Shape
If the battery module is installed in the receiving space, then appearance unity is maintained, but the structure becomes more complex
Solution Approach 1:
The receiving space for the battery module is merged with the frame body's structural design. The frame's tube structure is configured to form the receiving space as an integrated part of the frame, rather than adding a separate compartment. This merging maintains appearance unity while avoiding additional structural complexity by utilizing the frame's existing structural elements.

AI summary
A frame includes a frame body, a control unit, a first connector, a battery module and a second connector. The frame body has a receiving space formed therein, a first tube and a second tube. The first tube is combined with the second tube at a conjunction. An installed space is defined between the first tube and the second tube. An opening is formed on the conjunction, and the receiving space communicates with the installed space through the opening. The control unit is disposed within the receiving space. The first connector is disposed in the opening and coupled to the control unit. The battery module is detachably installed in the installed space. The second connector is disposed on the battery module and for engaging with the first connector when the battery module is installed in the installed space.
