Rear Axle Battery Mounting Base for Drill-Free E-Trike Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Converting a standard pedal tricycle to an electric tricycle requires selecting a battery enclosure type and determining a mounting location, often necessitating drilling holes into the frame, especially when the battery is placed in the rear basket.
Innovation Solution
A universal bolt-on rear rack type battery and accessory mounting base/basket riser that attaches to the tricycle axle cage through existing basket mounting holes, providing mounting points for up to three rear rack style batteries and accessories, eliminating the need for battery selection and frame drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery enclosure is permanently affixed to the tricycle frame by drilling mounting holes, then the battery is securely mounted, but the conversion process becomes complex and the frame is permanently modified
Solution Approach 1:
The patent introduces a mounting bracket as an intermediary component between the battery and the tricycle frame. This bracket attaches to the frame through the existing basket mounting holes without requiring additional drilling, and provides dedicated mounting points for the battery. This mediator resolves the contradiction by ensuring secure battery mounting while avoiding permanent frame modification and simplifying the conversion process.
Solution Approach 2:
The mounting bracket is designed to serve multiple functions: it attaches to the frame using existing basket mounting holes, provides secure mounting for the battery, and maintains compatibility with the original basket system. This multi-functionality allows the same component to address both security requirements and conversion simplicity without requiring separate specialized parts.
2Adaptability or versatility
If the battery is placed in the rear basket, then no additional mounting structure is needed, but the battery placement is inflexible and may not accommodate all battery types
Solution Approach 1:
The mounting system is segmented into distinct functional components: the bracket that attaches to the frame, the battery mounting plate that secures the battery, and the basket mounting holes that interface with the original basket system. This segmentation allows each component to be optimized for its specific function while maintaining overall flexibility and adaptability for different battery types and configurations.
3Reliability
If multiple mounting holes are drilled into the frame for battery mounting, then the battery can be securely attached, but the frame is permanently modified and the process becomes irreversible
Solution Approach 1:
The mounting bracket is designed to utilize the pre-existing basket mounting holes in the frame before any modification occurs. By preparing the mounting system to interface with these existing features, the patent eliminates the need for additional drilling operations that would permanently modify the frame, thereby maintaining reversibility while ensuring secure attachment.

AI summary
A fabricated carbon steel battery mounting bracket to bolt up to 3 rear rack style e-bike batteries on an adult tricycle. It bolts to the rear axle cage through the existing basket bolt holes and has 2 end supports that rest on and clamp around the axle outer tube. The basket is bolted to the top of the bracket through the holes above the battery positions.
