Photometric Scanner Housing With Movable Visor for Large Flat Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photometric stereo scanner housings are not designed to accommodate larger flat objects without requiring folding or crumpling, limiting their usability for items like scarves, shirts, and towels.
Innovation Solution
A housing design featuring a movable visor-shaped wall section that allows easy access to the interior, enabling larger flat objects to be placed unfolded, with lamps and cameras positioned to capture images from various angles, and a control unit to process these images using a photometric stereo method.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the housing uses a fixed closed structure with rigid walls, then the structural stability and enclosure are improved, but the accessibility for placing large flat objects is worsened
Solution Approach 1:
The housing incorporates a movable wall section that can transition between closed and open positions. This dynamic structure allows the housing to maintain stability during scanning while enabling easy access for placing large flat objects like scarves and shirts without folding or crumpling them.
2Area of stationary object
If the housing base is kept compact and small, then the device portability and size are improved, but the capacity to accommodate larger flat objects is worsened
Solution Approach 1:
The housing design allows the object to extend beyond the base area in the vertical dimension. The movable wall section opens upward to accommodate objects larger than the base footprint, enabling the compact base to handle larger flat objects by utilizing the third dimension rather than expanding the base area.
3Strength
If the housing walls are made rigid and fixed, then the structural integrity and light sealing are improved, but the ease of accessing the interior space is worsened
Solution Approach 1:
The housing wall is segmented into a fixed first wall section and a movable second wall section. This segmentation allows the majority of the structure to remain rigid for structural integrity and light sealing, while the movable section provides easy access to the interior space for placing and removing objects.

AI summary
A housing (12) for a photometric stereo scanner (10), the interior of which is easily accessible and which is also suitable for larger planar objects, comprises: - a base (16) having a first side edge (16a), a second side edge (16b) opposite the first side edge, and a front edge (16d) connecting the first and second side edges; - a ceiling (18) on which at least three lamps (38) can be mounted such that they are directed towards the floor; - a perimeter wall (20) connecting the base to the ceiling and having a first and a second wall section (20a, 20b); - a mount (36) on which a camera (14) can be mounted such that the camera is either mounted below the ceiling and directed towards the floor or mounted on the ceiling and directed towards the floor through an opening (32b) in the ceiling;wherein - the second wall section is essentially designed in the form of a helmet visor and is movably mounted on the floor, the ceiling and/or the first wall section; - the second wall section can assume a closed position in which it, together with the floor, the ceiling and the first wall section, encloses an interior space of the housing; - the second wall section can assume an open position in which the interior space is accessible from the outside and the first and second side edges and the front edge are exposed.;
