Solution Overview

Problem

Existing CIM-style motors face challenges when mounted vertically due to instability and wire routing issues, especially when used in applications requiring rotation in multiple planes and lacking parallel rails for attachment.

Innovation Solution

A vertical mount design that secures the motor beneath a surface, routing wires through a lower chamber and out of the mount, ensuring stability and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If brackets are used to screw into holes in the motor's body for vertical mounting, then the motor can be mounted vertically, but the system lacks stability when a gearbox is utilized

Engineering Contradiction:

Improvemounting stabilityVSAvoidmounting structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mounting structure is divided into separate functional components: a motor mount bracket that attaches to the motor body, a gearbox mount bracket that attaches to the gearbox, and a connecting structure that joins them. This segmentation allows each component to be optimized independently and provides more attachment points for improved stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The motor mount bracket is designed to nest within or alongside the gearbox mount bracket structure, creating a integrated assembly that distributes mechanical loads across multiple attachment points. The nested configuration enhances structural rigidity and mounting stability.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Adaptability or versatility

If the motor is mounted vertically with wires routed through the side, then the motor can be used in applications requiring rotation in x and z planes, but the wires may break due to improper routing

Engineering Contradiction:

Improveapplication versatilityVSAvoidwire reliability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

A wire routing channel or guide structure is introduced as an intermediary element between the motor and the external environment. This channel provides a protected pathway for wires to exit the motor housing, preventing direct exposure to mechanical stress and improving wire reliability while maintaining vertical mounting configuration.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If the motor is mounted horizontally as traditionally done in robotics competitions, then the wire routing is simple, but the mechanism cannot effectively rotate in x and z planes

Engineering Contradiction:

Improvewire routing easeVSAvoidrotation capability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The traditional horizontal mounting orientation is inverted to a vertical mounting configuration. This inversion changes the wire routing path but enables the mechanism to rotate effectively in x and z planes. The inversion is made feasible through the use of the motor mount bracket and protected wire routing channels.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A device that orients a motor with a rotating shaft on one end and wires on the other such that the rotating shaft faces upwards and the wires are routed out of the device through a lower chamber and a hole on its side while also being able to be mounted to a surface opposite the rotating shaft end.
