Beaded Connection for Robot Protective Jacket Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening methods for protective robot covers on painting robots are inadequate, as they fail to provide a reliable, secure, and process-reliable attachment, especially when exposed to paint and overspray, leading to contamination risks and damage to the robot components.
Innovation Solution
The use of piping connections, such as keder connections, to attach and detach a multi-part protective robot cover, which is adaptable to the robot's shape and can be easily replaced, ensuring a secure and paint-impermeable seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hook-and-loop fasteners are used to attach the robot protective cover, then the attachment can be easily applied and removed, but the fasteners lose their adhesive properties when contaminated with petroleum jelly or paint, providing only an unreliable connection
Solution Approach 1:
The patent employs disposable adhesive tapes that are replaced when contaminated, rather than attempting to maintain the adhesive properties of reusable fasteners. This disposable approach ensures reliable attachment during each use cycle while maintaining ease of operation through simple application and removal without tooling requirements.
2Strength
If snap fasteners are used to attach the robot protective cover, then the connection can be secure, but they only create a point connection and therefore cannot establish a continuous seal
Solution Approach 1:
The protective cover is divided into multiple segments or panels, each equipped with its own snap fasteners. This segmentation allows the cover to conform to the robot's complex geometry while maintaining continuous sealing through the distributed arrangement of multiple fastening points across the surface.
Solution Approach 2:
The patent combines snap fasteners with overlapping panel designs and sealing flaps. The snap fasteners provide secure mechanical attachment while the overlapping panel structure and sealing flaps create continuous seals between adjacent panels, merging mechanical strength with sealing continuity.
3Ease of manufacture
If adhesive tape is used to attach the robot protective cover, then the attachment can be simple to apply, but it must be done manually and is not reliable, and the tape must be cut again when removed which can damage underlying components
Solution Approach 1:
The patent replaces manual adhesive tape application with self-adhering materials that automatically bond upon contact with the robot surface. This mechanical substitution eliminates the need for manual cutting and reapplication, providing both ease of manufacture and reliable attachment through the self-adhering properties of the material.
4Device complexity
If rubber rings are used to attach the robot protective cover, then the connection can be simple, but they can only be used if the robot's protective suit has a completely ring-shaped structure and do not allow for precise positioning
Solution Approach 1:
Instead of requiring a complete ring-shaped structure, the patent segments the protective cover into multiple panels that can be independently positioned and fastened. This segmentation allows adaptation to various robot geometries while maintaining simple fastening mechanisms at each panel location.
Solution Approach 2:
The patent transitions from two-dimensional ring-shaped fastening to three-dimensional distributed fastening points across the robot's surface. This dimensional change allows precise positioning of individual panels while maintaining overall structural simplicity through standardized fastener designs.
