Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex structure of power supply lines in robots often leads to interference and damage at joint units, particularly in the arms and legs, due to the need for multiple power cables connecting actuators and electric parts.
Innovation Solution
A power supply unit with a simple structure that includes multiple power supply lines, bus bars, and plug-in power units with insulators and elastic connections, which distribute power efficiently and prevent cable interference by using sliding members and elastic members to maintain tension in connection cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power supply lines are used to connect actuators and electric parts, then power distribution capability is improved, but device complexity and cable interference increase
Solution Approach 1:
The patent combines multiple power supply lines and electrical connections into a single integrated power supply unit. This unit includes bus bars for multiple power lines, actuators, and electric parts all housed together, eliminating the need for separate external cables while maintaining full power distribution capability to all components.
Solution Approach 2:
The power supply unit serves multiple functions simultaneously: it distributes power to multiple actuators, provides electrical connections for various electric parts, and acts as a structural housing. This multi-functional design replaces what would traditionally require separate power cables, connection terminals, and mounting structures.
2Reliability
If power supply lines are disposed at specific positions, then power transmission is ensured, but space requirement and cable interference increase
Solution Approach 1:
The patent nests the power supply lines, bus bars, actuators, and electric parts within the confined space of the power supply unit housing. The bus bars are positioned within the housing, and electrical connections are made internally, effectively nesting multiple electrical components within a single structural unit, thereby minimizing the space required for cable routing and installation.
3Adaptability or versatility
If complicated power cable structure is used, then power distribution to multiple actuators is achieved, but cable damage risk increases
Solution Approach 1:
The patent merges all power distribution functions into the protected environment of the power supply unit housing. By combining multiple power lines, bus bars, and connections within a single enclosed unit, the system eliminates exposed external cables that would be susceptible to damage from joint unit interference, mechanical stress, and environmental factors.
