Solution Overview
Problem
Existing technologies face challenges in efficiently treating and inspecting objects with curved surfaces, particularly in high-throughput settings, as they struggle to maintain high resolution and accuracy while accommodating objects of various sizes and shapes, and often require complex mechanisms for gripping and alignment.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex gripping mechanisms are used to hold objects of various sizes and shapes, then adaptability is improved, but device complexity increases
Solution Approach 1:
The mandrel is designed as a universal gripping device that can accommodate objects of various sizes and shapes through a single standardized structure. The mandrel includes a body with an internal cavity that can receive different objects, and friction-imparting elements that can adapt to different object dimensions, eliminating the need for multiple specialized gripping mechanisms
Solution Approach 2:
The friction-imparting elements can change their friction characteristics dynamically to adapt to different objects. By adjusting parameters such as friction coefficient and contact pressure, the mandrel can securely hold various objects without requiring complex mechanical adjustments or multiple device configurations
2Manufacturing precision
If high-resolution treatment and inspection are applied to curved surfaces, then manufacturing precision is improved, but productivity decreases
Solution Approach 1:
The system dynamically adjusts the relative motion between the mandrel and the treatment/inspection apparatus. The mandrel can rotate at controlled speeds while the printhead or imaging unit moves along the object's surface, enabling high-resolution processing without requiring the entire system to slow down, thus maintaining productivity
Solution Approach 2:
The treatment and inspection processes are segmented into discrete zones along the production line. Multiple mandrels can be processed simultaneously by different printheads or imaging units, allowing parallel processing that maintains high throughput while each individual object receives high-resolution treatment
3Productivity
If multiple objects are processed simultaneously, then productivity is improved, but measurement precision deteriorates
Solution Approach 1:
The system incorporates feedback mechanisms through imaging units that continuously monitor the position and orientation of each object on the mandrel. This feedback is used by the control system to make real-time adjustments to the mandrel's rotation and the relative positioning of treatment apparatus, ensuring that each object is precisely aligned even during simultaneous processing of multiple objects
