Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots controlled by internal control apparatuses face heat-related failures due to heat generated by control components, which can lead to increased installation size and restricted placement, and existing solutions do not effectively manage temperature rises within the robot housing.
Innovation Solution
Incorporating a conversion element, such as a resistor, within the robot housing to convert regenerative currents into heat, and attaching it using an attachment member for efficient heat dissipation, thereby suppressing temperature rises and reducing installation area requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the control apparatus is built in the robot, then the installation area is smaller, but heat generated from control apparatus parts causes failure in robot parts
Solution Approach 1:
The patent divides the heat management function from the control apparatus by introducing a separate conversion element (resistor) that converts regenerative current to heat. This segmentation allows the control apparatus to remain compact while heat generation is handled by a dedicated component with proper thermal management, resolving the contradiction between small installation area and failure prevention.
Solution Approach 2:
The conversion element acts as an intermediary between the drive unit and the robot housing. It converts electrical energy to thermal energy in a controlled manner and dissipates heat through thermal conduction to the housing, preventing direct heat generation within the control apparatus while maintaining system compactness.
2Temperature
If the conversion element is attached to the robot housing, then temperature rise inside the robot housing is suppressed, but the structure becomes more complex
Solution Approach 1:
The patent merges the conversion element with the robot housing by attaching it directly to the housing structure. This integration allows the housing to serve dual purposes: as the structural enclosure and as a heat dissipation path, thereby suppressing temperature rise without significantly increasing device complexity.
3Temperature
If the conversion element is separated from the robot housing, then heat conduction to the housing is improved, but the installation area increases
Solution Approach 1:
The patent addresses heat conduction not by increasing spatial separation but by utilizing the thermal conduction path through the attachment member to the housing. The heat dissipation is achieved in the thermal dimension rather than requiring additional spatial separation, thus improving heat conduction efficiency without increasing installation area.

AI summary
A robot includes a robot housing containing a robot control apparatus that controls the robot having a motor, a brake that brakes the motor by short-circuiting between power lines for supplying electric power to the motor, and a conversion element that converts a current generated by braking of the motor by the brake into heat, wherein the conversion element is attached to the robot housing.
