Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motor control center units face challenges in compatibility and stability due to varying sizes and models of display mechanisms and installation plates, leading to potential malfunctions and increased component complexity.
Innovation Solution
A motor control center unit design that utilizes a common base and hinge bracket system, with a display mechanism installation plate fastened by a fastening member, and an anchor to ensure positional stability and minimize component count, while also locking the front door to prevent inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different sizes and models of display mechanisms and installation plates are used, then the display mechanism can be customized for different MCC unit sizes, but component compatibility and system reliability deteriorate
Solution Approach 1:
The patent applies universality by designing a standardized base structure and hinge bracket assembly that can accommodate different sizes and models of display mechanisms. The base includes standardized mounting features and the hinge bracket has a universal connection interface, allowing the same base-hinge-bracket assembly to work with various display mechanism configurations, thus achieving component compatibility across different MCC unit sizes while maintaining system reliability
2Adaptability or versatility
If different sizes and models of display mechanisms and installation plates are used, then display customization is possible, but device complexity increases
Solution Approach 1:
The base and hinge bracket are designed as universal components that can support multiple display mechanism types and sizes through standardized mounting interfaces, reducing the need for multiple specialized components and simplifying the overall device structure
Solution Approach 2:
The display mechanism assembly is segmented into modular components: the display mechanism itself, the installation plate, the base, and the hinge bracket. This segmentation allows for standardized interfaces between components, enabling flexibility in display mechanism selection without increasing overall system complexity
3Ease of manufacture
If the base is not firmly fixed, then installation is simpler, but stability and operational reliability deteriorate due to tilting
Solution Approach 1:
The base includes pre-formed protrusions that align with corresponding recesses in the hinge bracket, and the hinge bracket is pre-positioned on the drawer with proper orientation. This preliminary configuration ensures that when components are assembled, the base becomes firmly fixed without requiring complex adjustment procedures, thus maintaining both installation simplicity and base stability

AI summary
A motor control center (MCC) unit includes a drawer having a space for accommodating a circuit breaker, a hinge bracket installed on one of left and right sides of the drawer, a base connected to the hinge bracket by a hinge shaft, and a display mechanism installation plate fastened to the base by a fastening member. Although a display mechanism or a display mechanism installation plates are different according to sizes or models of the MCC unit, a base and a hinge bracket may be commonly used.
