Releasable Anchor Coupling for Strong Re-Engageable Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling systems face issues such as inability to release or re-engage anchors once installed, complexity in construction, poor fire resistance, aesthetic concerns, lack of strength, and inability to withstand lateral loading, among others.
Innovation Solution
A coupling system comprising an anchor with jaws and a release member, where the anchor can be actuated to disengage from the coupled member, allowing for release and re-engagement, and featuring an enclosing member to minimize movement and enhance strength, with tools for hydraulic or mechanical actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing coupling systems are used to connect members, then coupling strength is achieved, but the anchor cannot be released or re-engaged once installed
Solution Approach 1:
The coupling system transitions from a static permanent connection to a dynamic reversible connection. The jaw assembly can shift between engaged and disengaged positions relative to the coupled member, enabling the coupling to adapt its state based on operational requirements while maintaining strength during the engaged state
Solution Approach 2:
A release member is introduced as an intermediary component between the jaw assembly and the coupled member. This release member, when actuated by a tool, mediates the disengagement process by forcing the jaw assembly to move away from the coupled member, enabling controlled release without compromising the engaged state's strength
2Adaptability or versatility
If coupling parts intrude into the exterior surface of a column, then coupling function is achieved, but fire resistance and aesthetics are compromised
Solution Approach 1:
The coupling components (jaw assembly, body, enclosing member) are nested within the coupled member's interior space. The jaw assembly fits within the body, which is received within the coupled member, creating a compact nested structure that performs coupling functions without protruding into the exterior surface, thereby preserving fire resistance and aesthetics
3Ease of manufacture
If existing coupling designs are used, then basic coupling is achieved, but the construction is complex
Solution Approach 1:
The jaw assembly serves multiple functions: it engages the coupled member during installation, maintains the coupled position during service, and can be forced to disengage when a release tool is applied. The enclosing member simultaneously provides structural support, defines the interior space, and serves as a barrier. This multi-functionality reduces the need for separate components for each function, simplifying the overall construction

AI summary
A coupling system is described comprising an anchor that may releasably connect to a coupled member. Associated tools configured to cooperate with the coupling system and methods of use of the coupling system and release or re-engagement of the coupling system are also described. In one embodiment, the coupling system may further comprise an enclosing member and release member and a related tool or tools to actuate release of the connection and re-engage of the connection as desired.
