Printer Cover Mechanism Synchronized Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printer cover opening and closing mechanisms with pop-up mechanisms face issues where one end may not lock properly, leading to incomplete closure, jamming, and deformation due to biased force application, especially when using resin materials for cost and weight reduction.
Innovation Solution
A cover opening and closing mechanism featuring first and second contact members connected to the main body and cover, respectively, with a biasing member that ensures synchronized rotation and locking, preventing deformation and ensuring complete closure by maintaining a constant positional relationship between these members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pop-up mechanism is used to push open both sides of the cover independently, then the cover can be opened, but one end may not lock properly leading to incomplete closure and deformation
Solution Approach 1:
The pop-up mechanism is divided into two independent pop-up members (first and second pop-up members) that act on opposite sides of the cover independently. Each pop-up member has its own contact members and biasing member, allowing separate operation while maintaining synchronized locking through the locking mechanism.
Solution Approach 2:
The first and second contact members are connected to each other, merging their functions into a coordinated system. This connection ensures that when one contact member is pushed, the other is also pushed in a coordinated manner, preventing the cover from opening unevenly and ensuring complete closure.
2Ease of manufacture
If resin materials are used for cost and weight reduction, then manufacturing cost and weight decrease, but the cover becomes prone to deformation under biased force
Solution Approach 1:
The biasing members (springs) provide a counteracting force that balances the biased force applied during cover closure. This counterforce prevents the cover from deforming under uneven loading, allowing the use of lightweight resin materials without compromising structural integrity.
Solution Approach 2:
The biasing members are pre-loaded to provide cushioning force before the cover closure process begins. This beforehand cushioning prevents sudden biased forces from deforming the resin cover during the locking process, protecting the low-rigidity material from damage.
3Ease of operation
If the cover is pushed open at one end more than the other, then opening operation occurs, but the cover may not close completely leading to jamming
Solution Approach 1:
The connected contact members provide mutual feedback between the two sides of the cover. When one side is pushed during opening, the connection transmits this motion to the other side, ensuring synchronized opening and closing operations that prevent incomplete closure and jamming.
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
The mechanism ensures the cover can be securely opened and closed, preventing jamming and deformation, even when using low-rigidity materials, thereby maintaining recording quality and reducing operational issues.

AI summary
A cover is coupled to a main body casing in manner enabling rotation of the cover. A pop-up mechanism is provided that when locking by a locking mechanism that fixes the cover at a closed position in a releasable manner is released, rotates the cover from the closed position to an open position by a biasing of first contact members in a direction so that the first contact members push second contact members that are respectively disposed at both ends of the cover, the first contact members being connected to each other and respectively disposed at both ends of the main body casing. Thus, the second contact members are pushed while a positional relationship of the first contact members is maintained to be constant.
