Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information devices with cameras, such as laptops and smartphones, face challenges in assembling camera cover mechanisms due to narrow spaces, which can lead to deformation of springs and difficulties in assembly.
Innovation Solution
A camera cover unit with a cover case and a slidable cover body, featuring an elastic body and a protrusion that allows the cover body to move between positions, is designed to be assembled in a space with sufficient margin, using a cantilever arm and guide holes for easy assembly and minimizing deformation concerns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spring and protrusion mechanism is used to position the cover body, then the cover body can be positioned in first or second position, but the narrow upper frame portion may cause plastic deformation of the spring during assembly
Solution Approach 1:
The invention divides the positioning mechanism into separate functional elements: the elastic body provides positioning force while the guide protrusion on the cover case provides geometric constraint. This segmentation allows each component to be optimized independently, preventing spring deformation while maintaining reliable positioning.
Solution Approach 2:
The guide protrusion acts as an intermediary element between the elastic body and the cover body. It mediates the interaction by providing a fixed reference point that the elastic body can push against, ensuring that the positioning force is applied correctly without causing deformation to the elastic body itself.
2Reliability
If the camera cover unit is assembled in a narrow edge portion space, then the camera can be covered, but assembly becomes difficult and spring deformation may occur
Solution Approach 1:
The invention extends the positioning mechanism in the sliding direction by adding a guide protrusion that extends in the sliding direction. This dimensional extension allows the mechanism to be assembled in a more accessible orientation, making assembly easier while maintaining the camera cover function.
Solution Approach 2:
The guide protrusion is pre-formed on the cover case before assembly. This preliminary action provides a ready-made guide structure that simplifies the assembly process, allowing workers to easily align and install the cover body without complex positioning steps.
3Ease of operation
If the cover body is made slidable between positions, then the camera can be covered or exposed, but the elastic body may be deformed during assembly in narrow spaces
Solution Approach 1:
The invention applies different structural qualities to different parts of the mechanism: the guide protrusion provides rigid geometric constraint in one location, while the elastic body provides flexible positioning force in another location. This local differentiation allows the elastic body to maintain its deformation characteristics for smooth sliding while being protected from assembly damage.

Function Achieved in This Case
The solution facilitates easy assembly of the camera cover unit, reducing the risk of spring deformation and ensuring proper placement of components, making the assembly process more accessible and efficient.
Implementation Method 1
an elastic body that is elastically deformable inward and outward of the frame of the edge portion; and the cover case includes a protrusion that protrudes in a direction opposite to an acting part of the elastic body, and, upon the cover body sliding between the first position and the second position, presses and elastically displaces the acting part, so that thereafter the acting part goes over the protrusion

AI summary
An information device has a camera cover unit that is fixed to an upper edge in the outside of a display device in a back cover. The camera cover unit includes a cover case that is fixed to the upper edge and a cover body that is housed in the cover case and is slidable between a first position and a second position. The cover body includes an end that is placed in the first position to cover the front of the camera and placed in the second position to avoid the front of the camera, and a leaf spring that is elastically deformable inward and outward of the frame of the upper edge.
