Energy Storage Power Supply Housing for Bracket-Free Battery Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage power supplies have a large number of components, high manufacturing costs, and complex assembly processes due to the use of brackets and reserved mounting spaces, leading to increased volume.
Innovation Solution
The energy storage power supply incorporates a shell with detachable first and second cases that include positioning portions to fix battery modules and an inverter, eliminating the need for brackets and optimizing internal space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brackets are used to fix battery cells and mounting spaces are reserved for battery packs and inverters, then the battery cells can be securely fixed and components can be mounted, but the number of components increases, manufacturing costs increase, assembly complexity increases, and the overall volume increases
Solution Approach 1:
The patent merges the functions of the bracket and the mounting space reservation into the shell structure itself. The shell includes positioning portions that directly fix the battery module and inverter, eliminating the need for separate brackets. This integration reduces the number of components while maintaining secure fixation, directly resolving the contradiction between fixing reliability and device complexity
Solution Approach 2:
The shell is designed to perform multiple functions: it protects internal components, provides positioning portions for fixing the battery module, and creates mounting spaces for both the battery pack and inverter. By making the shell multi-functional, the patent eliminates the need for separate bracket structures, thereby reducing component quantity and assembly complexity while maintaining reliable fixation
2Reliability
If brackets and reserved mounting spaces are used, then components can be securely mounted, but manufacturing costs increase due to the large number of spare parts
Solution Approach 1:
The patent combines the mounting function into the shell structure itself through integrated positioning portions. This eliminates the need for separate bracket components, reducing the number of spare parts required and thereby lowering manufacturing costs while maintaining secure mounting of the battery module and inverter
Solution Approach 2:
The patent extracts the bracket function from the overall structure and integrates it into the shell. By taking out the separate bracket component and incorporating its fixing function directly into the shell's positioning portions, the patent reduces the number of parts that need to be manufactured and assembled, thus lowering manufacturing costs
3Ease of operation
If mounting space is reserved for battery pack and inverter in the shell, then components can be properly installed, but the volume of the energy storage power supply increases
Solution Approach 1:
The patent merges the mounting space reservation function into the shell's internal structure through positioning portions. The shell is designed with integrated spaces that accommodate both the battery module and inverter without requiring additional bracket structures or reserved volumes, thereby reducing the overall power supply volume while maintaining proper component installation
