Railing Securing Joint With Stepped Flange For Bolt Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional railing connection structures face issues with stability due to short locking distances and require tools that can be difficult to align in narrow spaces, making installation challenging.
Innovation Solution
A railing securing joint with a stepped shape, featuring a first member with a larger diameter and a second member with a smaller diameter and flexible claws, along with an internal flange and through hole for a bolt, allowing for enhanced stability and tool alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional block and bolt structure is used, then the structure is simple, but the locking distance is short and stability is poor
Solution Approach 1:
The patent introduces an internal flange structure that extends the bolt locking path from a single-plane insertion to a multi-dimensional path. The flange creates a stepped configuration where the bolt travels through the flange's thickness before engaging the block, effectively increasing the locking distance without significantly increasing the overall device complexity.
2Device complexity
If a conventional block with through holes is used, then the structure is simple, but the tool alignment is difficult in narrow spaces
Solution Approach 1:
The internal flange creates a stepped structure that provides additional spatial dimension for tool access. The recessed area formed by the flange allows screwdrivers or hex wrenches to be inserted at angles and still engage the bolt head properly, solving the alignment problem in narrow spaces without complicating the basic block structure.
Solution Approach 2:
The internal flange acts as an intermediary structure between the bolt and the external environment. It provides a platform that mediates the interaction between the locking tool and the bolt, allowing the tool to engage the bolt even when access space is limited, thus facilitating easier operation.
3Reliability
If the bolt locking distance is increased, then the stability is improved, but the device complexity increases
Solution Approach 1:
The block is segmented into multiple functional zones: the main body, the internal flange structure, and the recessed areas. This segmentation allows the bolt locking function to be distributed across these zones, extending the effective locking distance through the flange's thickness while keeping each segment relatively simple in design.

AI summary
A railing securing joint has a stepped shape and a first member having a larger diameter and a second member having a smaller diameter. The second member has a plurality of flexible claws, and each pair of the flexible claws has a dividing gap in between and a plurality of longitudinal ridges, such that each of the dividing gaps has a recess. One end of the first member facing the second member further has an internal flange, the flange is smaller than the second member to define a compression space between the second member and the flange. The flange further has a through hole passing through the first member for accepting a bolt for locking. An edge is formed between the first member and the second member.
