Nonlinear Image Capture Motion Control in Light Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture devices require manual operation or rely on robotic arms, which are cumbersome and not suitable for light boxes, leading to inaccurate and time-consuming image capture, especially when trying to capture objects from multiple angles within limited spaces.
Innovation Solution
A nonlinear motion and tilt angle control structure using dual or mono guiding rails, combined with stepping/servo motors and timing belts, allows for automated movement and rotation of the image capture device within a light box, enabling precise capture from top and side directions, and enabling the creation of 3D images through mathematical composition.

Engineering Contradiction Analysis
1Extent of automation
If a robotic arm is used to carry and rotate the image capture device, then automation is achieved, but the device becomes too heavy and complex for light box environments
Solution Approach 1:
The robotic arm system is segmented into separate functional modules: a guiding rail system for linear movement, a rotation mechanism for angular positioning, and an image capture device. This segmentation allows each component to be optimized independently and reduces overall system complexity while maintaining automation capabilities.
Solution Approach 2:
The heavy rotation set is extracted from the light box environment and positioned externally. Only the essential image capture device and lightweight guiding rails remain inside the light box, significantly reducing device complexity and weight while preserving automated image capture functionality.
2Adaptability or versatility
If a robotic arm with long swing arm is used, then rotation capability is improved, but durability decreases due to overloading
Solution Approach 1:
A guiding rail acts as an intermediary between the image capture device and the external rotation mechanism. The guiding rail provides precise linear guidance while the external rotation mechanism handles angular positioning, distributing mechanical loads and preventing overloading of any single component, thereby improving durability.
Solution Approach 2:
The system separates linear movement (handled by guiding rails inside light box) from rotational movement (handled by external rotation mechanism). This dimensional separation allows each subsystem to operate within optimal load ranges, improving reliability while maintaining full rotational capability.
3Device complexity
If manual operation is used, then device complexity is reduced, but image capture accuracy and speed deteriorate
Solution Approach 1:
The guiding rail system is designed with self-aligning features and automatic positioning mechanisms that ensure precise image capture without requiring complex manual adjustment. The system serves itself by maintaining optimal positioning through its inherent mechanical design, achieving high accuracy while keeping operational complexity low.

AI summary
Nonlinear movement and tilt angle control structure of an image capture device inside a light box includes a nonlinear motion set, a rotation set, a cartridge and a compartment. The nonlinear motion set uses dual guiding rails or a single guiding rail to drive the image capture device from top and side directions. The rotation set rotates the image capture device. The cartridge carries the rotation set and is driven by the nonlinear motion set to perform the nonlinear motion. And, the compartment is configured inside the rotation set to ride and fasten the image capture device.
