Solution Overview
Problem
Existing coupling elements in modular construction systems face challenges in providing simultaneous locking in both axial and rotational directions, leading to increased manufacturing complexity and a higher risk of locking mechanisms breaking off.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate locking elements are used to provide locking in both axial and rotational directions, then the locking reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent combines multiple locking functions (axial locking and rotational locking) into a single integrated coupling element. The coupling element includes a body with locking cams that engage with lips on the construction element, where the locking cams are resiliently movable toward and away from the lips. This single element simultaneously provides locking in both axial and rotational directions, eliminating the need for separate locking components and reducing overall device complexity while maintaining reliable locking in multiple directions.
Solution Approach 2:
The coupling element is designed as a multi-functional component that performs multiple locking functions. The locking cams can engage with the lips to provide axial locking, while the resilient movement capability allows the same locking cams to engage with protrusions for rotational locking. This universal design enables a single element to fulfill multiple locking roles that would traditionally require separate specialized components.
2Reliability
If multiple separate locking elements are used to provide locking in both axial and rotational directions, then the locking reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent combines multiple locking functions (axial locking and rotational locking) into a single integrated coupling element. The coupling element includes a body with locking cams that engage with lips on the construction element, where the locking cams are resiliently movable toward and away from the lips. This single element simultaneously provides locking in both axial and rotational directions, eliminating the need for separate locking components and reducing overall device complexity while maintaining reliable locking in multiple directions.
3Strength
If the locking mechanism is designed to engage firmly in both axial and rotational directions, then the strength of the connection is improved, but the risk of the locking mechanism breaking off increases
Solution Approach 1:
The locking cams are designed to be resiliently movable, allowing them to dynamically adjust during engagement. When the coupling element is inserted, the locking cams are pushed toward the lips and can flexibly engage with protrusions on the construction element. This resilient movement allows the locking mechanism to accommodate variations in positioning and reduces stress concentration, preventing the locking mechanism from breaking off while maintaining strong locking in both axial and rotational directions.
Solution Approach 2:
The resilient locking cams provide a cushioning effect during engagement. The elasticity of the locking cams allows them to deform elastically when engaging with the lips and protrusions, absorbing impact forces and reducing peak stresses. This beforehand cushioning prevents the locking mechanism from breaking off under high loads while ensuring firm engagement in both axial and rotational directions.
4Ease of manufacture
If a single coupling element integrates both axial and rotational locking functions, then the ease of manufacture is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple locking functions (axial locking and rotational locking) into a single integrated coupling element. The coupling element includes a body with locking cams that engage with lips on the construction element, where the locking cams are resiliently movable toward and away from the lips. This single element simultaneously provides locking in both axial and rotational directions, eliminating the need for separate locking components and reducing overall device complexity while maintaining reliable locking in multiple directions.
