Problem
Existing display stands lack efficient and easy-to-use mechanisms for securely attaching and detaching displays without the need for fasteners, leading to potential instability and difficulty in adjusting height and positioning.
Innovation Solution
A stand design featuring a base with connection protrusions and holes, a support with elastic wire and lever mechanism, allowing for secure attachment and detachment of the display without fasteners, ensuring stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stand uses traditional fasteners (screws or bolts) for attaching displays, then the attachment is secure and stable, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent replaces the traditional mechanical fastening system (screws or bolts) with a lever-based mechanical advantage system. The lever unit utilizes elastic deformation and mechanical leverage to achieve secure attachment without threaded fasteners. When the lever is actuated, it applies concentrated force to deform the elastic element, creating a strong clamping force that holds the display securely.
Solution Approach 2:
The elastic element in the lever unit provides self-service by automatically maintaining the clamping force. As the lever is pressed, the elastic element deforms and stores energy; when the lever is released, the elastic recovery automatically maintains the attachment force, ensuring continuous secure holding without requiring additional fastening operations.
2Ease of operation
If a stand uses a simple attachment mechanism without fasteners, then the ease of operation is improved, but the attachment stability and reliability deteriorate
Solution Approach 1:
The patent employs a dynamic attachment mechanism where the lever can be easily actuated to change the attachment state. The lever unit transitions between locked and unlocked positions through simple user input, allowing quick attachment and detachment while maintaining secure holding when engaged. The elastic element dynamically adjusts to maintain optimal clamping force.
Solution Approach 2:
The mechanism changes the physical state of the elastic element from undeformed to deformed when the lever is actuated. This parameter change in the elastic element's deformation state creates a corresponding change in clamping force, enabling the transition from an unattached to a securely attached state through simple lever movement.
3Reliability
If a stand uses multiple connection points for stability, then the attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple connection functions into a single integrated lever unit. The lever simultaneously engages with multiple connection holes and activates the elastic element to create clamping force across multiple attachment points. This merging of functions allows the user to secure the display at multiple locations with a single lever action, maintaining stability without increasing operational complexity.
