Self-Aligning Frame Coupling Mechanism for Conveyor Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing feeder conveyor systems face challenges in efficiently aligning and securely connecting frame members for easy assembly and disassembly, particularly for transportation and maintenance, as current solutions lack a reliable and efficient mechanism for aligning and coupling frame members.
Innovation Solution
A self-aligning and self-contained alignment and connection mechanism using a protrusion with a tapered outer surface and a corresponding alignment ring, combined with a threaded nut and washers, allows for precise alignment and secure coupling of frame members, enabling easy disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional connection mechanism is used for frame members, then the structure is simple, but the alignment precision and connection reliability are insufficient
Solution Approach 1:
The connection mechanism is divided into distinct functional components: a protrusion element on one frame member and a corresponding recess with alignment features on the other frame member. This segmentation allows each component to be optimized independently for its specific function while maintaining overall simplicity
Solution Approach 2:
The protrusion acts as an intermediary element that mediates between the two frame members, providing both alignment guidance and connection functionality. This single intermediary component resolves the contradiction by enabling reliable connection without requiring complex multi-component systems
2Productivity
If frame members are permanently connected, then structural stability is high, but transportation and maintenance efficiency are reduced
Solution Approach 1:
The connection mechanism transitions from a static permanent connection to a dynamic selectively detachable connection. The protrusion-recess interface with fastening elements allows the connection state to change between locked and unlocked, enabling efficient assembly/disassembly while maintaining stability when connected
Solution Approach 2:
The protrusion is pre-formed on the frame member with alignment features that guide the connection process. This preliminary preparation of alignment geometry ensures that when frame members are brought together, they self-align quickly and accurately before fastening, improving assembly efficiency without compromising structural stability
3Manufacturing precision
If a complex alignment mechanism is used, then alignment precision is high, but the device complexity and manufacturing cost increase
Solution Approach 1:
The alignment mechanism is designed to be self-aligning through the geometric relationship between the protrusion and recess features. The frame members themselves provide the alignment function through their inherent geometry rather than requiring separate active alignment devices, achieving high precision without increased complexity
Solution Approach 2:
The protrusion and recess features utilize asymmetric geometry where the shape and orientation of these elements provide unique alignment guidance. This asymmetric design ensures precise positioning in multiple degrees of freedom while maintaining simple manufacturing, as the asymmetric features are integrated into the frame member geometry rather than being separate components

AI summary
A machine includes a frame having a first frame member selectively coupled to a second frame member. The machine also includes an alignment and connection assembly including a protrusion coupled to the first frame member. The protrusion is receivable within the second frame member to align the first frame member with the second frame member. The alignment and connection assembly also includes a fastener coupled to the protrusion. The fastener is operable to secure the first frame member relative to the second frame member.
