Solution Overview
Problem
Conventional motor mounting assemblies face challenges in adjusting the position of motors in high-power industrial settings due to the need for expensive castings and reduced thread engagement, which can lead to mechanical wear and efficiency issues.
Innovation Solution
A motor mounting assembly featuring a motor base with elongate slots and threaded adjusting rods, along with a motor mounting fixture that includes a fixture body with legs and a coupling member with screw threads, allowing for precise adjustment of the motor's position without damaging the fixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional adjustable fixtures with threaded fasteners are used, then motor positioning is adjustable, but the fixture requires expensive castings and has reduced thread engagement
Solution Approach 1:
The fixture is divided into a base member and a separate adjustable member that can be independently positioned and secured. The adjustable member includes its own mounting slots and fastening mechanism, allowing it to be segmented from the base structure. This segmentation enables the adjustable member to be manufactured separately using simpler, less expensive processes while maintaining the overall adjustability function.
Solution Approach 2:
The fixture incorporates movable and adjustable components rather than fixed rigid structures. The adjustable member can be repositioned along the base member using threaded rods and locking mechanisms, providing dynamic positioning capability. This dynamic design allows the fixture to adapt to different motor positions without requiring complex castings for each configuration.
2Adaptability or versatility
If conventional adjustable fixtures are used, then motor position can be adjusted, but thread engagement is reduced leading to mechanical wear and efficiency loss
Solution Approach 1:
The fixture design incorporates pre-configured mounting slots and threaded holes at predetermined locations on the base member and adjustable member. These preliminary structural features are built into the components during manufacturing, ensuring that when the adjustable member is positioned and locked, the thread engagement occurs at optimized locations with sufficient engagement length. This preliminary preparation of mounting features prevents inadequate thread engagement and reduces mechanical wear during operation.
3Reliability
If expensive castings are used for adjustable fixtures, then sufficient thread engagement is achieved, but manufacturing cost increases significantly
Solution Approach 1:
By segmenting the fixture into base member and adjustable member, each component can be manufactured using appropriate, cost-effective processes. The base member can be manufactured with sufficient structural integrity using simpler methods, while the adjustable member with its mounting features can be produced separately. This eliminates the need for expensive castings to provide throughout the entire fixture, reducing manufacturing costs while maintaining adequate thread engagement capacity at the critical joining points.
Solution Approach 2:
The fixture design provides high structural quality and sufficient thread engagement capacity only at the critical locations where mounting and adjustment occur, rather than requiring expensive materials and complex castings throughout the entire fixture structure. The base member and adjustable member are designed with localized reinforcement and optimized mounting features at specific points, allowing cost-effective manufacturing in non-critical areas while ensuring reliability where needed.

AI summary
A motor mounting assembly and associated motor mounting fixture. The motor mounting fixture includes a fixture body, a motor fastener, and a coupling member. The fixture body has a fixture base and first and second spaced apart legs extending distally from the fixture base, a first aperture through the first leg and a second aperture through the second leg. The motor fastener projects proximally from the fixture base, and is received in the at least one elongate slot. The coupling member extends through at least the first aperture of the first leg and is fixed to at least one of the first and second legs. The coupling member has a through bore that includes screw threads that are threadably engageable with the adjusting rod such that the fixture body moves along the elongate slot of the motor base when the adjusting rod is rotated.
