Display Housing Snap-Fit Assembly Without Screws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional device housings, such as monitor housings, require numerous screws for assembly and disassembly, which is time-consuming and prone to screw loss.
Innovation Solution
A form-fitted enclosure design using spring-loaded tabs and receiving tabs that allow the display device bracket to be securely locked in an upright position without the need for screws, enabling easy setup and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous screws are used to assemble the housing, then the housing can be securely kept together, but the assembly and disassembly process becomes time-consuming and screws can be easily lost
Solution Approach 1:
The patent removes screws entirely from the housing assembly system and replaces them with a snap-fit mechanism using recesses and protrusions. This extraction of the screw fastening system eliminates the time-consuming assembly/disassembly process while maintaining housing security through the form-fitted configuration that engages automatically when components are assembled.
Solution Approach 2:
The housing components perform their own fastening function through the snap-fit mechanism. The protrusions on one component automatically engage with the recesses on another component when assembled, creating a self-securing connection without requiring external fastening elements like screws. This self-service mechanism eliminates both assembly time and the risk of losing fastening elements.
2Reliability
If numerous screws are used to assemble the housing, then the housing can be securely kept together, but the assembly process becomes complex and requires multiple fastening operations
Solution Approach 1:
The patent merges the fastening function into the structural design of the housing components themselves. The recesses and protrusions are integrated directly into the housing parts, combining what would traditionally be separate fastening elements (screws) and structural components into a unified snap-fit system. This reduces assembly complexity from multiple screw fastening operations to a single snap-together action while maintaining security.
3Productivity
If a form-fitted configuration without screws is used, then assembly becomes quick and secure, but the locking mechanism must provide sufficient holding force without mechanical fasteners
Solution Approach 1:
The patent employs spring-loaded plunger elements that provide dynamic locking force. The springs continuously apply force to maintain engagement between the form-fitted components, ensuring sufficient holding strength while allowing for easy assembly and disassembly. This dynamic mechanism compensates for the lack of mechanical fasteners by using elastic force to maintain the locked state.
Solution Approach 2:
The spring-loaded plungers act as intermediary elements between the form-fitted recesses and protrusions. These plungers transmit and amplify the engagement force, providing sufficient locking strength through the elastic properties of the springs while maintaining the screw-less design. The intermediary mechanism allows the form-fitted configuration to achieve the necessary holding force without direct rigid connection.

AI summary
A display device may be mounted at a predetermined angle via a free-standing display housing. In one example, the display device bracket may include at least two spring loaded tabs and a display monitor affixed to the display device bracket. A base mount may be on a resting surface with at least one side that is configured to make contact with the display device. A rear housing cover may also be included with at least two receiving tabs form-fitted to receive the spring loaded tabs and provide a secure spring-loaded locking position that maintains the display device bracket in a locked position and in an upright predefined angled viewing position.
