Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is fixed on the housing, then the structure is simple and stable, but the flexibility and convenience for secret shooting is poor
Solution Approach 1:
The camera is transformed from a fixed static position to a dynamically adjustable position along the flexible circuit board. The camera can be extended to various locations and retracted when not in use, providing dynamic adaptability for different shooting scenarios while maintaining a compact form factor.
Solution Approach 2:
The flexible circuit board is wound around the rotating roller when the camera is not in use, creating a nested configuration. This nesting principle allows the extended camera system to be compactly stored within the housing, reducing overall device complexity while maintaining flexibility during operation.
2Ease of operation
If the camera is extended for flexible shooting, then the convenience is improved, but the risk of circuit board damage increases
Solution Approach 1:
A flexible printed circuit board is used instead of rigid wiring to connect the camera. This flexible circuit board can bend and stretch as the camera is extended along its length, maintaining electrical connectivity while accommodating the dynamic movement without damage.
Solution Approach 2:
The flexible circuit board dynamically adjusts its configuration as the camera moves along its length. The circuit board flexes and extends with the camera movement, maintaining reliability throughout the range of motion rather than being constrained by a fixed rigid connection.
3Adaptability or versatility
If the flexible circuit board is made longer for extended range, then the flexibility is improved, but the device size increases
Solution Approach 1:
The flexible circuit board is wound around the rotating roller when not in use, creating a compact nested configuration. This allows a long flexible circuit board (providing extended range) to be stored in a small volume around the roller, resolving the contradiction between extension range and device volume.
Solution Approach 2:
Instead of extending the flexible circuit board in a straight line (one dimension), it is wound around the rotating roller, utilizing circular/rotational space (another dimension). This dimensional change allows the long circuit board to be compactly stored, reducing device volume while maintaining extension capability.
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 camera device provides flexible and covert shooting capabilities, allowing the camera to be easily extended and retracted, making it suitable for various usage scenarios, including secret recording.
Implementation Method 1
The elastic piece is a clockwork spring. An accommodating cavity is defined in a center of the central shaft. The clockwork spring is disposed in the accommodating cavity.
Implementation Method 2
The locking device further comprises a push rod and a torsion spring. The push rod is disposed on the first mounting frame. The push rod is connected to the check pawl. Amounting shaft portion and a stand column are disposed on the first mounting frame. The torsion spring is sleeved on the mounting shaft portion.
Implementation Method 3
The locking device comprises a ratchet disposed on the rotating roller and a check pawl disposed on the first mounting frame. When the check pawl is engaged with one of ratchet teeth of the ratchet, the check pawl locks the rotating roller in the elastic retracting direction.

AI summary
A camera device includes a rotating roller, a camera, a flexible circuit board, and a housing. The rotating roller is disposed in the housing, the flexible circuit board is of a strip shape. A first end of the flexible circuit board is connected to the camera. A second end of the flexible circuit board is connected to the rotating roller. The flexible circuit board is disposed around the rotating roller, so that the camera is flexibly stretchable through the flexible circuit board. When shooting, the housing is placed at a desired position, which is flexible and convenient to use. In addition, the camera is flexibly stretchable, so the camera is allowed to be applied to different usage scenarios. After use, the flexible circuit board is retracted to be disposed around the rotating roller by rotating the rotating roller to realize the storage of the flexible circuit board.
