Solution Overview
Problem
Conventional cover units have fixed areas, limiting their versatility in use due to their predetermined sizes, which restricts their application in various contexts.
Innovation Solution
An expandable cover unit design featuring a main body with slidable wing members and a wing driving unit utilizing magnets and gear mechanisms allows the area to be adjusted by user manipulation, enabling expansion and contraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cover unit has a fixed area according to intended purpose, then the manufacturing is simple and reliable, but the versatility and adaptability are limited
Solution Approach 1:
The cover unit is divided into a main body and multiple detachable wing members that can be independently positioned. The wing members are segmented and can be attached at different locations around the main body, allowing the cover area to be customized based on specific needs while maintaining a simple base structure.
Solution Approach 2:
The cover unit transitions from a static fixed-area design to a dynamic adjustable-area design. The wing members can be moved, attached, or detached to change the effective area of the cover unit, enabling adaptability without permanently complicating the structure.
2Adaptability or versatility
If the cover unit has a fixed area, then the structure is simple and reliable, but the usability in various contexts is restricted
Solution Approach 1:
The functional area of the cover is segmented into a core main body and optional wing members. This segmentation allows users to configure only the necessary portions for each specific task, improving usability while keeping the operational interface simple through standardized attachment mechanisms.
Solution Approach 2:
The main body serves as a universal base that can accommodate different numbers and positions of wing members. This multi-functionality allows the same basic structure to be used across various contexts by simply adjusting the wing member configuration, enhancing usability without complicating operation.
3Adaptability or versatility
If wing members are slidable to expand area, then the versatility is enhanced, but the device complexity increases due to sliding mechanisms
Solution Approach 1:
The wing members are designed as separate, modular components that slide along the main body. This segmentation allows each wing member to be independently controlled and positioned, achieving area adjustability through simple individual sliding actions rather than complex integrated mechanisms.
Solution Approach 2:
The sliding mechanism replaces more complex mechanical attachment systems. By using simple sliding guides or tracks integrated into the main body, the wing members can be easily repositioned without requiring screws, clips, or other complicated fastening mechanisms, thus enhancing area adjustability while minimizing mechanism complexity.
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 expandable cover unit can change its area according to user needs, enhancing its versatility and allowing it to be used in a wider range of applications, such as container lids and sunscreens.
Implementation Method 1
an attractive magnet which is installed on an outer circumferential surface of the manipulation member and generates an attractive force with respect to the fixed magnet to move the wing member toward the manipulation member
Implementation Method 2
a repulsive magnet which is installed on an outer circumferential surface of the manipulation member at a position spaced apart from the attractive magnet in a direction in which the manipulation member rotates or moves upward or downward, and generates a repulsive force with respect to the fixed magnet to move the wing member in the direction away from the manipulation member

AI summary
The present disclosure relates to an expandable cover unit including a main body, a manipulation member installed on the main body to be rotatable or moveable upward or downward, an expanding portion installed on the main body at a position adjacent to the manipulation member and provided with at least one wing member installed on the main body to be slidable in a direction away from the manipulation member such that an end portion of the wing member protrudes outward from the main body, and a wing driving unit configured to operate the wing member to move the wing member according to the manipulation member rotated or moved upward or downward by a manipulation of a user.
