Rotary Motor Terminal Module With Vibration-Absorbing Busbars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing terminal modules for rotary electric machines have multiple components, increasing complexity and requiring time and effort to join the main body portion and terminal portions, while also failing to effectively absorb vibration.
Innovation Solution
A terminal module for rotary electric machines is designed with integrally formed busbars made of metal plates and covered by an electrically insulating resin holding member, featuring elongated extension portions that absorb vibration and are connected to a terminal block, reducing the number of components and enhancing flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main body portion and terminal portions of the busbar are provided separately, then the busbar can be assembled flexibly, but the number of components increases and assembly time and effort increase
Solution Approach 1:
The patent merges the main body portion and terminal portions into a single integrally formed busbar component. This eliminates the need for separate assembly of multiple busbar parts, reducing the total number of components while maintaining the flexibility to configure terminal portions at desired locations along the busbar length.
2Adaptability or versatility
If multiple separate components are used for the busbar, then customization is possible, but time and effort is needed to join the main body portion and terminal portions
Solution Approach 1:
The terminal portions are pre-integrated into the busbar during manufacturing, with terminal portions positioned at predetermined locations along the busbar length. This preliminary configuration eliminates the need for time-consuming assembly operations while maintaining the ability to customize terminal positions based on application requirements.
3Object-affected harmful factors
If a flexible main body portion is used to absorb vibration, then vibration transmission is reduced, but the structure becomes more complex with separate components
Solution Approach 1:
The flexible main body portion and vibration-absorbing characteristics are integrated into a single busbar component. The busbar's inherent flexibility, derived from its construction from metal plate material, provides vibration absorption while maintaining structural simplicity and eliminating the need for separate vibration damping components.
