Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a camera module is integrated into a display module to form a display assembly, then the overall device structure becomes more compact and integration is improved, but the display module can no longer be separately replaced or upgraded
Solution Approach 1:
The patent divides the camera module into separable components: the first lens assembly that remains integrated with the display module, and the second lens assembly that can be independently replaced. This segmentation allows the display module to maintain compact integration while enabling selective replacement of the second lens assembly for upgrades or repairs.
Solution Approach 2:
The patent introduces a movable support structure that allows the second lens assembly to be dynamically positioned between an installed state (integrated with the display module) and a removed state (separated for replacement). This dynamic mechanism enables the system to transition between integrated and replaceable configurations.
2Volume of moving object
If the distance between the display module and camera module is reduced for compactness, then device size is minimized, but optical performance deteriorates due to insufficient light transmission distance
Solution Approach 1:
The patent employs a foldable optical path using a reflective member (mirror) that redirects light at an angle, effectively increasing the optical transmission distance within a reduced physical space. This allows sufficient light path length for optimal optical performance while maintaining compact device dimensions.
Solution Approach 2:
The patent nests the reflective member within the compact space between the display module and camera module, creating a folded optical path that maximizes the use of available space. This nested configuration enables longer optical paths without increasing the overall device volume.
3Reliability
If the optical path is extended to improve optical performance, then light transmission is enhanced, but the device volume increases
Solution Approach 1:
The reflective member redirects the optical path in a different spatial dimension, creating a folded configuration that extends the light transmission distance without increasing the linear dimensions of the device. This allows improved optical performance within compact device volume.

AI summary
An optical arrangement (1) comprising a base (10), a first optics group (3), an actuator (6), and a first retaining element (7) moving in response to rotation of said actuator (6). The base (10) maintains said first retaining element (7) in a first rotary position (R1), such that said actuator (6) rotation converts to movement of said first retaining element (7) from a first linear position (L1) to a second linear position (L2) along an optical axis (A1). The base (10) disengages said first retaining element (7) when reaching said second linear position (L2), such that said actuator (6) rotation rotates said first retaining element (7) to a second rotary position (R2) in which said first retaining element (7) can return to said first linear position (L1) by decompression of a resilient element (9), moving said first optics group (3) from a retracted position (P1) to an extended position (P2).
