Swivel Base Support Layout for Battery Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing swivel working machines face issues such as vibration transmission from the electric motor and hydraulic pump to the battery, difficulty in attaching the electric motor and hydraulic pump components, and increased machining costs for battery support structures.
Innovation Solution
The design includes a support portion that is separate from the support body and attached to the swivel base via mounting devices, with the electric motor and hydraulic pump positioned to minimize vibration transmission and facilitate easy attachment, and a machining method that reduces the area subjected to machining for battery placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electric motor and hydraulic pump are positioned close to the battery on the swivel base, then the device complexity is reduced, but vibrations from the motor and pump transmit to the battery reducing reliability
Solution Approach 1:
The patent divides the support structure into two separate portions: a support body for mounting the battery and a separate support portion for mounting the electric motor and hydraulic pump. This segmentation isolates the vibration-generating components from the battery while maintaining overall device integration, thus reducing vibration transmission without significantly increasing complexity.
2Device complexity
If the electric motor and hydraulic pump are attached using a support portion integrated with the support body, then the device complexity is reduced, but the area requiring machining increases leading to higher manufacturing costs
Solution Approach 1:
The support structure is segmented into a support body and a separate support portion that is attached via mounting devices. This allows the support portion to be independently manufactured and mounted, reducing the total machining area required on the swivel base and lowering manufacturing costs while maintaining structural integration.
Solution Approach 2:
The support portion is designed to be attachable at multiple positions on the support body through mounting devices, providing spatial flexibility. This dimensional adaptability allows optimization of the attachment location to minimize machining requirements while maintaining functional integration.
3Ease of operation
If the electric motor and hydraulic pump are positioned for easy attachment, then the ease of operation is improved, but vibrations transmit more directly to the battery reducing reliability
Solution Approach 1:
The support portion is designed as a separate, modular component that can be easily attached and detached from the support body using mounting devices. This segmentation enables simple installation and maintenance operations while the separate positioning isolates vibrations from the battery, simultaneously improving ease of operation and maintaining reliability.
4Stability of the object's composition
If a large area of the support body is machined for battery placement, then the battery stability is improved, but the manufacturing cost increases
Solution Approach 1:
The battery support function is separated from the main swivel base by introducing a distinct support body with dedicated mounting features. This segmentation concentrates the machining requirements to specific localized areas on the support body rather than requiring large-area machining of the swivel base, achieving battery stability with reduced manufacturing cost.
