Lock Retainer Snap-Fit for Fast Modular Wall Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting extruded-member frameworks to form temporary wall frameworks, such as those used in trade show displays, are inefficient, costly, and lack flexibility in accommodating various frame shapes and sizes.
Innovation Solution
A modular wall frame system featuring a lock retainer and lock cassette that can be easily attached and detached via a snap-fit mechanism without tools, allowing for secure connection of adjacent wall frame elements and supporting panels of different shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional connection methods are used for extruded-member frameworks, then structural stability is achieved, but assembly time and cost increase significantly
Solution Approach 1:
The connection system is divided into separate modular components: a lock retainer attached to one frame element, and a lock cassette attached to the adjacent frame element. This segmentation allows each component to be independently manufactured and quickly assembled, eliminating the need for complex integrated connection mechanisms and significantly reducing assembly time.
Solution Approach 2:
The lock cassette is designed to nest within the lock retainer structure, with the lock cassette inserting into a recess of the lock retainer. This nesting arrangement allows for compact storage during transport and rapid deployment during assembly, as the components fit together like nested dolls without requiring additional fastening operations.
2Reliability
If traditional fastening systems are used, then secure connection is achieved, but device complexity and cost increase
Solution Approach 1:
The lock retainer includes a spring-loaded detent mechanism that automatically engages with the lock cassette upon insertion. This self-service feature provides secure locking without requiring manual intervention, tools, or complex adjustment procedures, thereby maintaining connection reliability while minimizing device complexity.
Solution Approach 2:
The invention replaces traditional mechanical fastening systems (screws, bolts, welds) with a simplified snap-fit engagement mechanism. The lock cassette inserts into the lock retainer and is secured by a spring detent that automatically engages, substituting complex mechanical assemblies with a single-action insertion and release system.
3Adaptability or versatility
If fixed connection methods are used, then structural integrity is maintained, but adaptability to various frame shapes and sizes is reduced
Solution Approach 1:
The lock retainer and lock cassette are designed as universal connection components that can be attached to any extruded frame element regardless of its specific dimensions or orientation. The standardized interface allows the same connection mechanism to serve multiple functions across different wall sections, enabling flexible frame configurations while maintaining consistent structural integrity throughout the display system.

AI summary
A lock retainer for facilitating the secured connection of an adjacent pair of wall frame elements to one another by way of a lock cassette having an actuatable grip portion is disclosed. The lock retainer may comprise a flange portion disposed between a proximal portion and distal portion. A cassette compartment may retainingly engage a portion of the lock cassette with the grip portion remaining outward the lock retainer. The proximal portion is configured to be mounted in a retainer mounting aperture in a frame segment of a wall frame element. The lock retainer may include a retainer detent moveable between a securing and releasing positions. The detent may be resiliently biased toward the securing position. The detent may be on a detent lever having a release actuation portion enabling a user to manually overcome the resilient bias. Also disclosed is a modular wall frame system incorporating the lock retainer.
