Display Stand Lever Assembly for Screwless Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display stands lack efficient and easy-to-use mechanisms for securely attaching and detaching displays without the need for fasteners like screws or bolts.
Innovation Solution
A stand design featuring a base with connection protrusions and holes, a lever unit with an elastic wire, and a support system that allows for separable attachment and detachment of the display, utilizing a lever mechanism to lock and unlock the display securely to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional fasteners like screws or bolts are used to attach the display to the stand, then the attachment is secure and stable, but the attachment and detachment process becomes complex and time-consuming
Solution Approach 1:
The connection interface is segmented into multiple connection protrusions on the base and corresponding connection holes on the support, allowing independent engagement points that provide both ease of insertion and secure attachment through distributed contact points
Solution Approach 2:
The lever unit acts as an intermediary mechanism that translates a simple rotational motion into a locking action, mediating between the user's input and the secure attachment state without requiring direct manipulation of fasteners
2Loss of time
If a simple connection mechanism without fasteners is used, then the ease of attachment and detachment is improved, but the reliability and stability of the connection deteriorates
Solution Approach 1:
The connection protrusions and holes are pre-configured in specific positions and orientations, allowing the support to be preliminarily positioned on the base before the lever locking action, ensuring proper alignment and reducing the time required for attachment
Solution Approach 2:
The lever unit utilizes curved or rounded geometric features that allow for smooth rotational motion and provide a large contact area during engagement, enabling quick insertion while maintaining strong mechanical interlocking through the curved geometry
3Stability of the object's composition
If multiple connection points are provided to enhance stability, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple connection protrusions and corresponding holes are merged into a single integrated connection interface where the lever unit simultaneously engages with all connection points, providing stable multi-point attachment while maintaining simple overall structure through functional integration

Function Achieved in This Case
Enables easy and rapid attachment and detachment of displays without the use of fasteners, ensuring stable support and preventing accidental dislodging.
Implementation Method 1
an elastic wire including a rear end hinge-connected to the lever, while a front end is in contact with the at least one support protrusion in a state where the front end is pressed against the at least one support protrusion
