Robot Base Cover Sliding Detachment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Horizontal articulated robots face issues with deformation and wire disconnection due to unexpected shocks when the connecting section is on the outer side of the base, and time-consuming detachment of covers when the section is on the inner side, leading to increased manufacturing costs and operational inefficiencies.
Innovation Solution
A robot design featuring a base with a cover section that allows easy detachment by sliding in a direction crossing the wire insertion direction, a housing section to fix the connecting section, and a fastening member axis located outside the housing section to prevent contact and facilitate wire management, reducing the time required for cover detachment and preventing deficiencies in the connecting and second wires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting section is disposed on the outer side of the base, then the wire connection is accessible, but deformation occurs due to unexpected shocks
Solution Approach 1:
The connecting section is extracted from the base and disposed on a separate disposing section, physically isolating it from shock-prone areas while maintaining wire connection accessibility. This separation allows the connecting section to be protected from deformation caused by unexpected shocks to the base.
2Reliability
If the connecting section is disposed on the inner side of the base, then it is protected from shocks, but the cover detachment work takes time
Solution Approach 1:
The cover is segmented with a cutout section that allows it to be detached by simple sliding motion rather than requiring complete removal of multiple fastening members. This segmentation enables quick access to the connecting section while maintaining protection when closed.
Solution Approach 2:
The cover is designed to transition dynamically between closed (protected) and open (accessible) states through a simple sliding motion enabled by the cutout section. This dynamic design reduces the time required for detachment while maintaining protection during operation.
3Strength
If multiple screws are used to fasten the cover to the base, then the cover is securely fixed, but detachment work takes time
Solution Approach 1:
The cutout section extracts material from the cover to create a region where fastening members can be quickly released. This allows the cover to be detached by sliding motion without requiring the complete removal of multiple screws, reducing detachment time while maintaining secure fixation during operation.
4Reliability
If waterproof finish is applied to prevent deficiencies, then reliability improves, but manufacturing cost increases
Solution Approach 1:
The cover is designed with a cutout section that allows the connecting section to be accessible without requiring waterproof seals or protective coatings. By preliminarily designing the structure to allow controlled access, the need for expensive waterproof finishing is eliminated while still preventing deficiencies during operation.
