Rotatable Polygonal Camera Module Testing System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera module testing systems require extensive linear space due to the conical nature of lens fields of view and rectangular image sensors, leading to inefficient use of space and the need for exclusive 'keep-out' areas between modules and targets.
Innovation Solution
A rotatable polygonal structure with faces configured to receive camera modules and targets, allowing multiple camera modules to be tested in a circular or polygonal arrangement, with controlled rotation and lighting to optimize space usage and minimize interference areas.

1Productivity
If camera modules are tested in a linear arrangement, then testing can be performed in assembly-line fashion, but extensive space is required due to keep-out areas between modules and targets
Solution Approach 1:
The patent transitions from a linear one-dimensional testing arrangement to a rotational two-dimensional polygonal structure. Camera modules are positioned on the perimeter of a rotating polygon, allowing them to face inward toward a central target. This dimensional change eliminates the need for linear keep-out areas while maintaining testing functionality through rotational positioning.
Solution Approach 2:
The patent employs a polygonal structure that approximates a circular arrangement, with camera modules positioned around the perimeter facing a central target. This curved/circular layout optimizes space utilization compared to linear arrangement, as it allows the conical fields of view to converge toward the center without requiring extensive linear separation distances between modules.
2Productivity
If multiple camera modules are tested simultaneously, then testing throughput increases, but interference between modules and targets must be avoided
Solution Approach 1:
The polygonal/circular arrangement positions multiple camera modules around a central target, with each module's conical field of view directed inward toward the center. This geometric configuration allows multiple modules to simultaneously test the same target without lateral interference, as their fields of view converge toward the central point rather than extending outward into adjacent module spaces.
Solution Approach 2:
The rotational polygonal structure enables multiple camera modules to access the central target from different angular positions around the perimeter. This two-dimensional radial arrangement allows simultaneous testing by multiple modules without the field of view conflicts that would occur in a linear one-dimensional arrangement, where modules would block each other's views.

If a rotatable polygonal structure is used, then space efficiency improves, but the system complexity increases
Solution Approach 1:
The rotating polygonal structure serves multiple functions: it positions camera modules in the optimal radial arrangement, enables rotational access to the central target, and provides a compact framework that integrates both the modules and targets. This multi-functional design consolidates what would otherwise require separate positioning mechanisms into a single unified structure.
Solution Approach 2:
The patent introduces rotational movement to the testing system, allowing the polygonal structure to rotate and bring different camera modules into position to test different targets. This dynamic element replaces what would otherwise require multiple stationary testing stations, reducing overall system complexity while maintaining space efficiency.

AI summary
An example system for testing camera modules may include: a polygonal structure that is rotatable, where the polygonal structure includes faces, each of which is configured to receive at least one camera module under test; and targets facing at least some of the faces of the polygonal structure, where each target is usable in testing a corresponding camera module facing the each target.
