Robot Cable Protection via Detachable Sealed Distributing Boxes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots lack effective water-resistant and dust-resistant designs for their internal cables, which can lead to damage from frequent washing or exposure to harsh environments, and existing solutions may overengineer these capabilities, increasing costs.
Innovation Solution
The design incorporates detachable distributing boxes with sealed compartments that house the robot's internal cables and connectors, providing a high level of water-resistant and dust-resistant protection without the need for extensive redesign, allowing for flexible configuration based on installation environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional robot structures without dedicated cable protection are used, then device complexity is reduced, but reliability deteriorates due to cable damage from water and dust exposure
Solution Approach 1:
The robot structure is segmented by introducing separate distributing boxes that house and protect cable bundles. These boxes are detachably mounted on the base, creating distinct protected zones for cables while leaving the rest of the robot structure simple and conventional.
2Reliability
If detachable distributing boxes with sealed compartments are added, then reliability improves through water and dust protection, but device complexity increases
Solution Approach 1:
The distributing boxes are designed to be detachable rather than permanently fixed, allowing dynamic configuration. Users can attach or remove the boxes based on environmental requirements, enabling the system to adapt its protection level without permanently increasing complexity.
3Reliability
If extensive water-resistant design is implemented throughout the robot, then reliability improves, but manufacturing cost increases due to overengineering
Solution Approach 1:
Water-resistant properties are applied locally only where cables are exposed to environmental hazards. The distributing boxes provide sealed protection specifically for cable entry points and bundled cables, while other parts of the robot maintain conventional construction without expensive water-resistant treatments.
4Reliability
If distributed cable routing without centralized protection is used, then device complexity is reduced, but reliability deteriorates due to exposed cables in harsh environments
Solution Approach 1:
Multiple individual cable protection measures are merged into a single integrated distributing box structure. Instead of protecting each cable separately or routing them through complex individual channels, all cables are bundled and housed together in one sealed compartment with a unified mounting interface.

AI summary
A robot including a base, a first movable part, and a second movable part supported on the first movable part. The base includes an opening portion through which ends of inner cables disposed within the robot are inserted. The robot includes a number of distributing boxes that are detachably attached to the opening portion or to a portion near the opening portion of the base. The distributing boxes respectively include, robot-side walls through which ends of the inner cables are inserted in order to dispose the ends of the inner cables within the distributing boxes, and relay walls provided with connectors to which outer cables from a control device for the robot are connected.
