Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen connecting devices do not allow screens to pivot to a 0° position for parallel alignment, and they lack ease in snapping into specific angular positions, making them inefficient for transport, storage, and space management.
Innovation Solution
A screen connecting device featuring first and second hinge members with a pivot pin and complementary latching surfaces, allowing wide pivoting range and secure latching in various angular positions, including 0°, 60°, and 90°, through elongated holes and snap-in connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If simple hinges are used for screen connection, then the device structure is simple, but the screens cannot pivot to a 0° position for parallel alignment
Solution Approach 1:
The hinge member is segmented into two parts: a first hinge member attached to one screen and a second hinge member attached to the other screen. These segmented parts work together with complementary latching surfaces to enable both wide pivoting range including 0° position and structural simplicity.
Solution Approach 2:
The hinge connection is made dynamic through the elongated hole that allows the pivot pin to move along its length. This dynamic adjustment enables the screens to pivot through a wide range of angles including 0° parallel alignment, while the latching surfaces provide stability when needed.
2Ease of operation
If simple hinges are used for screen connection, then manufacturing is simple, but the screens cannot be easily snapped into specific angular positions
Solution Approach 1:
The latching surfaces have specific local geometries with凸起和凹陷 features that engage at predetermined angular positions. This local quality enhancement at critical points enables easy snapping into specific angles while keeping the overall manufacturing process relatively simple.
Solution Approach 2:
The hinge design incorporates parameter changes in the form of complementary latching surfaces with specific geometries. These geometric parameters are designed to engage at specific angular positions, enabling easy snapping into predetermined orientations while maintaining manufacturing feasibility.
3Adaptability or versatility
If screens are hinged with fixed pivot position, then the hinge structure is simple, but the screens cannot be pivoted together to parallel position for transport
Solution Approach 1:
The pivot position is made dynamic through the elongated hole that allows the pivot pin to move along its length. This enables the hinge to adapt to different screen angles including the parallel 0° position for transport, while the overall mechanism remains relatively simple.
Solution Approach 2:
The elongated hole introduces a degree of freedom in another dimension (along the length of the hole) rather than constraining the pivot to a fixed point. This dimensional change enables the screens to achieve parallel alignment while keeping the hinge mechanism simple.

AI summary
The invention relates to a screen connecting device having a first and a second joint element (4a, 4b) and a swivel pin (5) for the jointed connecting of the first and second joint elements (4a, 4b), wherein said elements can be locked to each other in at least one angular position. The joint elements (4a, 4b) comprise an oblong hole (25a, 25b) and rest surfaces (19, 24). Two interacting joint elements (4a, 4b) can be pivoted over a wide angular range by moving the swivel axis (32) along the oblong holes (25a, 25b) and locked in at least one angular position.
