C-Shaped Rail Assembly System with Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly systems for wind turbines, particularly those using C-shaped rails and T-shaped nuts, are inadequate for precise positioning and retention of assembly elements in large constructions where access is limited to one side, making it difficult to correctly position traditional nuts relative to bolts.
Innovation Solution
An assembly system with a C-shaped rail and a movable retaining element that includes a locking mechanism, such as elastically deformable locking elements, to securely position and retain assembly elements like bolts or rivets, allowing for easier insertion and secure fixation without simultaneous access to both sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional T-shaped nuts are used in C-shaped rails, then the assembly system provides flexibility for positioning, but it becomes impossible to correctly position nuts relative to bolts when access is limited to one side
Solution Approach 1:
A retaining element acts as an intermediary between the C-shaped rail and the assembly element (bolt). The retaining element includes a locking claw that engages with a locking surface on the rail, and a retaining surface that receives the assembly element. This intermediary structure enables secure positioning and locking of bolts from one side only, eliminating the need for simultaneous access to both sides while maintaining positioning flexibility.
2Manufacturing precision
If locking mechanisms are added to retain assembly elements, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The locking claw and retaining surface are merged into a single retaining element that is integrated with the C-shaped rail structure. The locking surface is formed as part of the rail's locking mechanism, and the retaining element combines both locking and retaining functions in one component. This merging reduces the number of separate parts and simplifies the overall structure while achieving precise positioning.
3Adaptability or versatility
If the retaining element is made movable in the rail, then flexibility is improved, but reliability of retention is worsened without proper locking
Solution Approach 1:
The retaining element is designed to be movable along the C-shaped rail during assembly, allowing flexible positioning at different locations. Once positioned, the locking claw engages with the locking surface to lock the retaining element in place, transforming it from a movable state to a fixed state. This dynamic design provides both positioning flexibility and reliable retention.
