Opening and Closing Device for Electronic Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with a display that rotates out of a housing, the first and second connecting rotors can cause interference, making it difficult to remove the display from the housing.
Innovation Solution
An opening and closing device with a base plate, pivotably attached first and second plates, and a detachable system that allows the display to be easily removed by rotating the third plate around a second shaft, while a bias system biases the second plate to separate from the first shaft and a restriction system prevents sliding when rotated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first and second connecting rotors are used to allow the display to rotate out of the housing, then the display can be tilted and positioned at different angles, but the display or cover may interfere with the housing, making it difficult to remove the display from the housing
Solution Approach 1:
The connecting mechanism is divided into three separate plates (first plate, second plate, third plate) connected by shafts, allowing incremental separation. The detachable system enables the third plate to be separated from the first plate by applying force to rotate around the second shaft, facilitating easy display removal while maintaining positioning capability when assembled
Solution Approach 2:
The second plate acts as an intermediary component between the first and third plates. It includes a bias system that biases the second plate away from the first shaft, and a restriction system that allows sliding when superposed but restricts sliding when rotated, mediating the interaction between the display and housing
2Adaptability or versatility
If the first and second connecting rotors are used to allow the display to rotate out of the housing, then the display can be tilted and positioned at different angles, but the structure becomes complex with multiple rotating components
Solution Approach 1:
The connecting mechanism is divided into three separate plates (first plate, second plate, third plate) connected by shafts, allowing incremental separation. The detachable system enables the third plate to be separated from the first plate by applying force to rotate around the second shaft, facilitating easy display removal while maintaining positioning capability when assembled
Solution Approach 2:
The restriction system dynamically changes its behavior based on the state of the second plate. When the second plate is superposed to the first plate, the restriction system allows sliding along the first shaft. When the second plate is rotated with respect to the first plate, the restriction system restricts sliding, providing adaptive constraints
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy removal of the display from the housing without interference, allowing for secure and efficient tilting and accommodation of the display panel.
Implementation Method 1
a first shaft that is provided in the first plate; a second shaft that is provided in the second plate and that has an axial direction that is different from that of the first shaft
Implementation Method 2
a bias system configured to bias the second plate to the first plate in a direction to separate from the second shaft along the first shaft
Implementation Method 3
a detachable system configured to lock the third plate and the first plate in a state in which the first plate, the second plate, and the third plate are superposed, wherein the detachable system is configured to separate, upon application of force to the third plate that is for rotating the third plate around the second shaft, the third plate from the first plate
Implementation Method 4
a restriction system that is fixed to the second plate, wherein the restriction system is configured to allow the second plate to slide along the first shaft in a state in which the second plate is superposed to the first plate, and the restriction system is configured to restrict the second plate from sliding along the first shaft in a state in which the second plate is rotated with respect to the first plate around the first shaft
