Mechanical Lock Structure for Seamless Prefab Component Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection structures for prefabricated building components require an operation space for margin adjustment, which cannot meet the requirement for seamless connection, leading to cumbersome and complex operation steps and low construction efficiency.
Innovation Solution
A mechanical lock for building component connection comprising a plug element and a lock body part, where the plug pin structure is movably installed in the plug shell and the bracing structure includes a tight abutting part that stops the plug pin structure from retreating, allowing for firm and reliable connection without the need for an operation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an existing connection structure with movable insertion rod and screw joint is used to allow margin adjustment, then the adaptability of the connection is improved, but the operation space requirement increases and seamless connection cannot be achieved
Solution Approach 1:
The connection structure is divided into two separate components: the plug element with plug pin structure and the lock body part with bracing structure. This segmentation allows each component to be optimized independently - the plug pin can be inserted without requiring operation space for adjustment, while the bracing structure provides the necessary mechanical support and positioning.
Solution Approach 2:
The plug pin structure is pre-configured with a stop part that will engage with the bracing structure. The bracing structure is pre-installed in the lock body part with the tight abutting part positioned to receive the stop part. This preliminary configuration eliminates the need for post-insertion adjustment, enabling seamless connection.
2Adaptability or versatility
If an existing connection structure with multiple moving parts is used to allow margin adjustment, then the adaptability is improved, but the operation steps become cumbersome and complex
Solution Approach 1:
The adjustment function is extracted from the insertion process itself. Instead of requiring adjustment movements during insertion, the plug pin structure is designed with a stop part that automatically engages with the pre-positioned bracing structure, separating the insertion action from the adjustment action.
Solution Approach 2:
The plug pin structure and bracing structure are designed to self-align and self-lock. The stop part of the plug pin automatically engages with the tight abutting part of the bracing structure upon insertion, eliminating the need for manual adjustment operations or complex multi-step procedures.
3Adaptability or versatility
If an existing connection structure is used that requires operation space for margin adjustment, then the adaptability is improved, but the construction efficiency decreases
Solution Approach 1:
By segmenting the connection into a plug element and lock body part with distinct functions, the insertion operation becomes a simple single-action process. The plug pin structure with stop part engages with the bracing structure in one motion, eliminating the multiple adjustment steps required by traditional structures, thereby improving construction efficiency.
Solution Approach 2:
The bracing structure is pre-positioned in the lock body part with the tight abutting part ready to receive the stop part. This preliminary positioning ensures that when the plug pin is inserted, the engagement occurs automatically without requiring additional adjustment operations, significantly reducing assembly time and improving productivity.
