Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motors face issues such as lack of a debug window for easy parameter adjustment and shaft fixation, inadequate heat dissipation due to confined space, simple control functions, poor line tightness, and absence of communication interfaces, making installation and operation cumbersome and inefficient.
Innovation Solution
A motor design with a control board in a bottom-mounted control box featuring a debug window, an overlapped control board structure, rotary dip switch, and aluminum construction for improved heat dissipation, along with a platform for secure cable and power line connections, and a sealing system for waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the control board is disposed in the control box, then the control functions are integrated, but the space is small and heat dissipation becomes difficult
Solution Approach 1:
The control box is divided into an upper portion and a lower portion by a partition wall. The upper portion houses the control board for integrated control functions, while the lower portion is dedicated to heat dissipation with a heat dissipation cover and ventilation structures. This segmentation separates the control integration function from the heat dissipation function, allowing both to coexist effectively.
Solution Approach 2:
A heat dissipation cover is introduced as an intermediary component between the control board and the external environment. The heat dissipation cover includes ventilation holes and is positioned to facilitate air flow, acting as a mediator that enables effective heat dissipation while maintaining the integrated control structure within the control box.
2Device complexity
If no debug window is disposed on the control box, then the structure is simple, but connection and parameter adjustment become troublesome
Solution Approach 1:
A debug window is pre-configured on the control box, equipped with a sealing cover that can be opened. This preliminary preparation allows users to easily access the control board for wire connection and parameter adjustment when needed, while maintaining structural simplicity and sealed integrity during normal operation. The debug window is designed to be opened only when maintenance or parameter adjustment is required.
3Ease of operation
If the power line and signal line extend from side wall of the control box, then the connection is established, but tightness is not good enough
Solution Approach 1:
A sealing cover is introduced as an intermediary component that covers the debug window and the areas where power lines and signal lines extend. The sealing cover maintains the sealed state of the control box during normal operation, while allowing access when needed. This intermediary component ensures both connection convenience and sealing tightness are achieved.
Solution Approach 2:
The sealing cover acts as a flexible sealing element that can be opened for access and then closed to restore tightness. This flexible sealing mechanism allows the control box to maintain good tightness while still enabling convenient connection and parameter adjustment operations through the debug window.
4Device complexity
If no communication interface is provided, then the structure is simple, but communication with outside world is inconvenient
Solution Approach 1:
The debug window is designed to serve multiple functions: it provides access for wire connection, parameter adjustment, and communication interface connection. By making the debug window multi-functional, the patent adds communication capability without significantly increasing structural complexity. The same access point serves multiple purposes, maintaining simplicity while enhancing versatility.
