Modular Drive System Asymmetrical Bracket Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular drive systems for machines like track-type tractors do not allow for independent access or separation of motor drive assembly components, and they are not designed to enable interchangeable mounting of motor drive assemblies on opposite sides of the machine, leading to complex maintenance and customization challenges.
Innovation Solution
A modular drive system with a motor drive assembly featuring a motor housing with a specific bolt pattern, a brake assembly with matching bolt patterns, and a final drive assembly, along with frame mount configurations that allow for inverted mounting on opposite sides of the machine, enabling easy interchangeability and maintenance of motor drive assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If motor drive assemblies are separately configured for each side of the machine, then each assembly can be optimized for its specific mounting location, but the device complexity increases and maintenance becomes more difficult
Solution Approach 1:
The motor drive assembly is divided into separable components (motor assembly, brake assembly, final drive assembly) that can be independently accessed and maintained. The bracket assembly acts as a common mounting interface that segments the complexity from the mounting location requirements.
Solution Approach 2:
The bracket assembly with its mount features serves multiple functions: it provides the mounting interface for the motor drive assembly, accommodates fluid passageways, and enables installation on either side of the machine frame. This universal interface reduces the need for side-specific configurations.
2Ease of repair
If motor drive assemblies include multiple separate parts, then each part can be independently maintained, but the device complexity increases due to multiple connections and passageways
Solution Approach 1:
The bracket assembly merges multiple functions into a single component: it serves as the mounting structure, contains the fluid passageways for lubrication and cooling, and provides the interface for electrical and hydraulic connections. This consolidation reduces the number of separate connections required.
Solution Approach 2:
The bracket assembly acts as an intermediary component that mediates between the motor drive assembly components and the machine frame. It consolidates multiple connection points (mount features, fluid passageways, connection interfaces) into a single accessible assembly that can be serviced as one unit.
3Adaptability or versatility
If different motor drive assemblies are used on opposite sides of the machine, then each side can be optimized for its specific requirements, but the manufacturing cost and complexity increase
Solution Approach 1:
The bracket assembly incorporates asymmetric mount features that allow the same motor drive assembly to be correctly oriented on either side of the machine. The bracket's geometry and feature arrangement accommodate the asymmetric requirements of left and right mounting locations while using a symmetric base design.
Solution Approach 2:
The bracket assembly can be inverted or flipped to accommodate mounting on opposite sides of the machine frame. This inversion capability allows the same component design to serve both left and right mounting locations, eliminating the need for side-specific custom designs.
4Manufacturing precision
If motor drive assemblies require specific orientations for mounting, then the assembly can be optimized for that orientation, but the ease of operation and maintenance decreases
Solution Approach 1:
The mount features on the bracket assembly are asymmetrically arranged to guide correct orientation during installation. The asymmetric geometry provides mechanical guidance that ensures the assembly is installed in the correct orientation without requiring complex alignment procedures.
Solution Approach 2:
The bracket assembly design creates equivalent mounting conditions on both sides of the machine through symmetric base geometry with asymmetric feature arrangement. This allows the assembly to be installed in either orientation with equal ease, eliminating orientation-specific installation difficulties.
