Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot control devices with heating elements, such as servo amplifiers, have complex structures due to airtight compartments and multiple components, which complicates their design and maintenance.
Innovation Solution
A control device for robots featuring a casing with a main body and a door that opens to create a communicable passage between chambers, allowing air to flow through blower devices for heat dissipation, simplifying the structure and reducing component count by using heat sinks and strategically placing blower devices near openings for efficient heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a drawer structure with airtight sealing and ventilation ducts is used, then heat dissipation is improved, but device complexity increases
Solution Approach 1:
The patent removes the drawer structure and ventilation ducts from the control device. Instead of using a complex airtight compartment with forced air circulation, the invention extracts the heat dissipation function to rely on natural convection through openings in the casing, thereby eliminating unnecessary components while maintaining effective heat removal.
Solution Approach 2:
The patent divides the internal space into multiple chambers separated by partition walls, with each chamber having independent openings for heat dissipation. This segmentation allows heat from different components to be dissipated independently through natural convection, eliminating the need for a unified complex ventilation system.
2Temperature
If multiple components including drawer, ventilation duct, and electrical connection structures are used, then heat dissipation is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent combines multiple functions into the casing structure itself. The casing walls serve as both structural elements and heat dissipation pathways through integrated openings. Partition walls separate chambers while maintaining structural integrity. This merging eliminates the need for separate drawer assemblies, ventilation ducts, and electrical connection structures, significantly simplifying manufacturing and assembly.
3Ease of operation
If a door structure with penetrations is used, then accessibility is improved, but airtightness deteriorates
Solution Approach 1:
The patent applies different quality requirements to different parts of the door structure. The door includes openings for accessibility, but the partition walls and chamber boundaries maintain airtight sealing where needed. This local differentiation allows the door to provide access while the overall structure maintains necessary airtightness for heat dissipation control.
