Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric wheel sets are difficult to remove from vehicles without assistance, and the process of installing a removable power module is cumbersome due to alignment issues with mechanisms like stop, gear, and clutch systems, reducing user convenience.
Innovation Solution
A wheel set with a quick-release engaging device featuring a wheel hub and transmitting member with elastic members and corresponding engaging holes and members, allowing for easy installation and uninstallation without alignment requirements, and enabling the power module to be removed independently, thus reducing weight for delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the power module is integrated with the wheel hub using traditional fastening methods, then the connection strength is sufficient, but the installation and removal process becomes complex and requires assistance
Solution Approach 1:
The engaging device is divided into multiple independent components: wheel hub, transmitting member, engaging members, and elastic members. This segmentation allows the power module to be quickly assembled and disassembled by simply connecting or disconnecting these modular parts, eliminating the need for complex fastening operations and external assistance.
Solution Approach 2:
The elastic members automatically engage the transmitting member with the wheel hub when the power module is installed, and automatically disengage when removed. This self-actuating mechanism eliminates the need for external assistance or complex manual operations during installation and removal, while maintaining secure connection during operation.
2Weight of moving object
If the power module is designed to be removable for delivery convenience, then the weight reduction for delivery is achieved, but alignment problems arise during installation
Solution Approach 1:
The engaging members and engaging holes are designed with asymmetric shapes that provide built-in alignment guidance. The unique shape configuration ensures that the transmitting member can only be inserted in the correct orientation, automatically achieving proper alignment with the wheel hub's stop mechanism, gear mechanism, and clutch mechanism without requiring multiple angle adjustments.
Solution Approach 2:
The engaging members act as intermediary elements between the transmitting member and the wheel hub. These intermediaries guide the alignment process by fitting into corresponding engaging holes, ensuring that all internal mechanisms (stop mechanism, gear mechanism, clutch mechanism) are properly aligned during installation without requiring precise manual positioning.
3Weight of moving object
If the power module is removed from the wheel set, then the weight is reduced for delivery, but the wheel set cannot function as an ordinary wheel
Solution Approach 1:
The wheel set is designed with universal functionality through the removable power module configuration. The basic wheel structure can function independently as an ordinary wheel when the power module is removed, while also being capable of functioning as a powered wheel when the power module is installed. This multi-functional design allows the same wheel set to adapt to different operational requirements.
