Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding technologies are limited in their ability to efficiently process multiple workpieces of varying heights and internal surfaces simultaneously, as they typically require workpieces to be of the same height and can only handle external flat surfaces, leading to inefficiencies and precision issues.
Innovation Solution
A workpiece carrier unit with rotatably mounted workpiece carriers on roller bearings, allowing for independent rotation and adjustment of each carrier, enabling simultaneous processing of multiple workpieces of different heights and internal surfaces, with the grinding tool rotating to reach all workpieces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple workpiece holders are used to process multiple workpieces simultaneously, then productivity is improved, but only workpieces of the same height can be ground and only external flat surfaces can be processed
Solution Approach 1:
The workpiece carriers are made dynamically adjustable through tiltable and foldable mechanisms. Each workpiece carrier can be independently tilted and folded to adapt to workpieces of different heights and geometries, enabling the system to process diverse workpiece types while maintaining simultaneous multi-workpiece capability.
Solution Approach 2:
The system changes geometric parameters of the workpiece carriers by tilting and folding them. This parameter adjustment allows the carriers to accommodate workpieces of varying heights and orientations, transforming a fixed-configuration system into a variable-configuration system that maintains versatility across different workpiece types.
2Device complexity
If only the workpiece holder with the currently machined workpiece rotates, then device complexity is reduced, but processing efficiency and precision are limited
Solution Approach 1:
The system transitions from a static single-rotation mode to a dynamic multi-rotation mode. Multiple workpiece carriers can rotate independently in addition to the workpiece carrier unit rotation, creating coordinated motion patterns that improve grinding efficiency and precision without excessive complexity increase.
Solution Approach 2:
The rotation function is segmented and distributed across multiple independent workpiece carriers. Each carrier can rotate independently about its own axis, allowing parallel processing operations and improving overall system productivity while maintaining manageable complexity through modular design.
3Manufacturing precision
If workpiece carriers are mounted on roller bearings with independent rotation capability, then manufacturing precision and adaptability are improved, but device complexity increases
Solution Approach 1:
Roller bearings are introduced to enable dynamic, low-friction rotation of workpiece carriers. This dynamic mounting allows precise positioning and rotation control, improving dimensional accuracy while the modular bearing-based design keeps the complexity increase manageable through standardized components.

AI summary
A workpiece carrier unit (4) with several workpiece carriers (5, 5', 5") is shown and described, wherein the at least two workpiece carriers (5, 5', 5") are rotatably mounted about a workpiece carrier axis (X5), and wherein the workpiece carrier unit (4) is rotatably mounted about a workpiece carrier unit axis (X4). To enable low-friction and precise mounting of the workpiece carriers (5, 5', 5"), it is proposed that the workpiece carriers (5, 5', 5") be mounted on rolling bearings.
