Compact Hobby Robotics Gearbox With Nested Mounting Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hobby robotic systems often require increased torque, but existing gearboxes are cumbersome and limit component coupling, making them unsuitable for space-limited assemblies.
Innovation Solution
A compact gearbox assembly is designed with a strategically placed mounting plate, sunken output shaft bearings, and versatile mounting features, allowing the gearbox to fit within the motor's dimensions and provide additional coupling options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a gearbox is added to increase torque, then torque output is improved, but the assembly size increases and becomes cumbersome
Solution Approach 1:
The mounting plate is strategically nested within the gearbox housing, with its mounting features positioned inside the gear system area. This allows the mounting functionality to be contained within the gearbox's existing footprint, preventing additional volume increase while maintaining torque multiplication capabilities
Solution Approach 2:
The mounting features are positioned in a different spatial dimension (within the gear system area rather than on the external surface), allowing the coupling function to be achieved without increasing the external dimensions of the gearbox assembly
2Adaptability or versatility
If a traditional mounting plate is used, then component coupling is achieved, but coupling flexibility is limited
Solution Approach 1:
The mounting plate integrates multiple mounting features (through-holes, counter-sunk holes, recesses) that can accommodate different component types and coupling methods. This multi-functional design allows a single mounting plate structure to provide various coupling options, increasing adaptability without requiring multiple separate mounting components
Solution Approach 2:
The mounting plate is divided into multiple discrete mounting features (through-holes, counter-sunk holes, recesses) rather than a single monolithic structure. This segmentation allows selective use of different mounting features depending on the specific component being coupled, providing flexibility while keeping each individual feature simple

AI summary
A motor gearbox system includes a motor. The system further includes a mount configured to couple to the motor. The system also includes a housing configured to couple to the mount, and a coupler configured to couple to the housing, the coupler having at least one mounting feature configured to couple to a component. The system further includes a gear system operably coupled to the motor and configured to be disposed, at least in part, within a gearbox formed by the coupled mount, housing and coupler. The system includes an output shaft operably coupled to the gear system.
