Battery Supporting Plate Mounting for Distortion Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixation of batteries to a metal-frame construction machine causes local high stresses due to distortion from welding, risking battery damage.
Innovation Solution
A construction machine with a supporting plate installed via elastic mounts on the machine-body frame, where batteries are fixed without welding to the supporting plate, and additional elastic mounts are used to reduce distortion effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries are fixed directly to the machine-body frame via welding, then the fixation is strong and reliable, but the welding causes distortion of the machine-body frame which generates local high stresses and damages the batteries
Solution Approach 1:
A supporting plate is introduced as an intermediary component between the machine-body frame and the batteries. The supporting plate is installed on the machine-body frame via elastic mounts rather than direct welding, which mediates the connection and prevents distortion-induced stress from being transmitted to the batteries while maintaining reliable fixation.
Solution Approach 2:
The welding process is extracted and removed from the connection between the supporting plate and batteries. By eliminating welding at this interface, the source of distortion and associated stress is removed, while the supporting plate maintains battery fixation through alternative means.
2Object-affected harmful factors
If elastic mounts are used to install the supporting plate on the machine-body frame, then distortion-induced stress on batteries is reduced, but the device complexity increases
Solution Approach 1:
Elastic mounts serve as intermediary elements between the machine-body frame and the supporting plate. These mounts absorb and isolate distortion forces while maintaining the structural connection, reducing harmful stress transmission to the batteries with relatively simple elastic components.
Solution Approach 2:
The mounting method changes from rigid welding to elastic mounting, altering the mechanical parameters of the connection. This parameter change allows the system to accommodate frame distortion without transmitting excessive stress to the batteries, while the elastic mounts themselves remain relatively simple components.
