Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing open-close and image forming apparatuses face challenges in controlling the moving speed of movable components, leading to potential damage and inefficiency due to unregulated motion.
Innovation Solution
Incorporating a limiting section, such as a limiting plate with a higher dynamic coefficient of friction, between movable members to control and reduce their moving speed by applying frictional forces, thereby mitigating impact and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a movable member is provided in an open-close apparatus, then the apparatus can perform its function (e.g., opening and closing operations), but the moving speed of the member cannot be controlled, leading to potential damage and inefficiency
Solution Approach 1:
A limiting section is introduced as an intermediary component between the movable member and the apparatus main body. This limiting section includes a limiting surface that contacts the movable member during its movement, thereby mediating the interaction and controlling the moving speed through friction without requiring complex control systems.
Solution Approach 2:
The patent changes the friction parameter by using a limiting section with a higher dynamic coefficient of friction than the surrounding surfaces. This parameter change allows the limiting section to control the moving speed of the movable member through increased frictional force, transforming the uncontrolled motion into regulated movement.
2Speed
If the moving speed of a movable member is not limited, then the member can move freely and quickly, but impact and wear occur during operation
Solution Approach 1:
The limiting section is positioned to engage with the movable member before the member reaches high-speed impact zones. By introducing frictional resistance in advance through the limiting surface, the system cushions the potential impact and reduces wear before it occurs, rather than reacting after damage has happened.
Solution Approach 2:
The patent converts the potentially harmful high-speed motion into a beneficial controlled movement by using the limiting section. The friction that would normally be considered resistance is transformed into a useful controlling force that regulates speed and prevents damage, turning a harmful effect into a beneficial control mechanism.
