Resilient Connector Assembly for Blind Modular Coupling Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of modular structures faces challenges such as limited access to upper and lower surfaces during vertical coupling, which can hinder efficient assembly and maintenance. Additionally, environmental hazards can lead to structural failures, necessitating improved connector designs for stability and repairability.
Innovation Solution
A connector system comprising a first joint member with a tubular outer and inner wall, and a second joint member with similar structures, connected by a fastener that extends through multiple openings to secure the joint members. This system facilitates blind couplings and includes features like yield plates and lateral couplers to enhance stability and accessibility.

Engineering Contradiction Analysis
1Ease of operation
If traditional connectors are used for vertical coupling of modular structures, then structural stability is achieved, but access to upper and lower surfaces is limited, hindering efficient assembly and maintenance
Solution Approach 1:
The connector is divided into multiple components including a first joint member, second joint member, fastener, yield plate, and lateral coupler. This segmentation allows each component to serve specific functions: the joint members provide connection points, the fastener secures the assembly, the yield plate provides structural reinforcement, and the lateral coupler enables access to surfaces for assembly and maintenance operations.
Solution Approach 2:
The lateral coupler extends perpendicular to the main vertical coupling axis, creating a new dimensional access path. This allows workers to access the upper and lower surfaces of modular structures from the side rather than having to work from above or below, thereby improving accessibility without compromising vertical structural stability.
2Ease of repair
If conventional connector designs are used, then assembly is straightforward, but repairability is difficult due to limited access and structural integration
Solution Approach 1:
By segmenting the connector into removable components (fastener, yield plate, lateral coupler), the design enables selective replacement of damaged parts without requiring complete connector replacement. The segmented structure allows maintenance personnel to access and replace individual components through the lateral coupler access path.
Solution Approach 2:
The lateral coupler acts as an intermediary access mechanism that provides a pathway for tools and replacement components to reach the joint members and fastener. This intermediary structure facilitates repair operations without requiring dismantling of the entire modular structure or compromising structural integrity.
3Object-affected harmful factors
If simple connector designs are used, then manufacturing costs are low, but resistance to environmental hazards is insufficient
Solution Approach 1:
The connector employs composite construction combining multiple materials with complementary properties: the joint members provide structural framework, the yield plate offers ductility and energy absorption, and the fastener provides secure mechanical connection. This composite approach enhances resistance to environmental hazards such as corrosion, moisture, and temperature variations while maintaining manufacturing feasibility through standardized component production.
Solution Approach 2:
The yield plate is positioned to provide beforehand cushioning against environmental stresses and structural failures. This component is designed to deform plastically under extreme loads, absorbing energy and preventing catastrophic failure of the entire connector assembly, thereby providing proactive protection against environmental hazards.

AI summary
A connector includes a first joint member, a second joint member, and a fastener. The first joint member includes a first tubular outer wall at least partially enclosing a first outer cavity, and a first tubular inner wall at least partially enclosing a first inner cavity. The second joint member includes a second tubular outer wall at least partially enclosing a second outer cavity, and a second tubular inner wall at least partially enclosing a second inner cavity. The fastener extends through first and second openings of the first inner cavity, and through first and second openings of the second inner cavity to position the first joint member relative to the second joint member.
