Sealed Robot Controller Layout for Waterproof Dustproof Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing industrial robots lack a controller with equivalent waterproof and dustproof performance, necessitating separate measures for the controller's disposition, which is cumbersome and inefficient.
Innovation Solution
The robot integrates a control board, power supply board, and drive board within a sealed robot main body, using multiple sealing members to ensure waterproof and dustproof performance, with external connection portions and detachable wiring connections for ease of repair and adaptation to varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the controller is disposed separately from the robot or placed in a protective box to achieve waterproof performance, then the robot can operate in waterproof environments, but the design complexity and installation trouble increase significantly
Solution Approach 1:
The patent integrates the controller into the robot arm structure, merging previously separate components (controller and robot arm) into a unified waterproof unit. The controller is housed within the robot arm's casing with sealing measures, eliminating the need for separate protective boxes or dispositions and reducing installation complexity while maintaining waterproof performance.
2Reliability
If the controller is disposed separately from the robot to achieve waterproof performance, then the robot can operate in waterproof environments, but additional protective boxes and wiring connections are required
Solution Approach 1:
The controller is integrated into the robot arm structure, combining previously separate components into a unified waterproof unit. This integration eliminates the need for separate protective boxes and complex wiring connections, significantly improving installation convenience while maintaining waterproof performance.
3Device complexity
If the control board and power supply board are integrated inside the robot main body, then the robot structure becomes more compact and wiring is simplified, but thermal management becomes more challenging
Solution Approach 1:
The patent segments the internal space of the robot arm into distinct regions: one for heat-generating components (motor, drive board) and another for temperature-sensitive components (control board, power supply board). This spatial segmentation allows compact integration while managing thermal interference through physical separation and targeted cooling measures.
4Reliability
If the robot arm is sealed with multiple sealing members to achieve waterproof performance, then the robot can operate in waterproof environments, but maintenance and repair become more difficult
Solution Approach 1:
The patent employs detachable sealing structures and modular design elements that allow the sealing system to be dynamically accessed for maintenance. The casing can be disassembled to expose internal components, and sealing members are positioned to allow inspection and replacement without complete disassembly, balancing waterproof integrity with maintenance accessibility.
