Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measuring devices are used for each component, then measurement precision is maintained, but device complexity and quantity increase
Solution Approach 1:
The patent implements a universal measuring device with a movable support structure that can be positioned at multiple locations and orientations on a single workpiece. The support unit can move along guides in different directions and be oriented at various angles, allowing one device to perform measurements that previously required multiple specialized devices for different components.
2Reliability
If specialized measuring devices are used for each component, then measurement reliability is improved, but storage space and setup time increase
Solution Approach 1:
The measuring device is designed as a universal system that can measure various components without requiring separate specialized devices. The movable support structure with multiple degrees of freedom allows the same device to adapt to different component geometries and measurement locations, eliminating the need for multiple storage locations for different measuring devices.
Solution Approach 2:
The support structure incorporates movable elements that can dynamically adjust position and orientation during measurement operations. The support unit can move along guides, change angles, and reposition itself to accommodate different measurement requirements, providing the adaptability previously achieved only through multiple static specialized devices.
3Measurement precision
If multiple specialized measuring devices are used, then measurement precision is maintained, but setup time and calibration processes increase
Solution Approach 1:
The patent describes a universal measuring device that can measure different components with the same apparatus. The movable support structure allows rapid repositioning and reorientation without requiring device changes or extensive recalibration, maintaining measurement precision while significantly reducing setup time compared to swapping between multiple specialized devices.
4Manufacturing precision
If conventional fixed positioning devices are used, then positioning accuracy is achieved, but adaptability to different shapes is reduced
Solution Approach 1:
The patent implements a dynamic support structure with movable elements that can adjust position and orientation. The support unit can move along guides in multiple directions and be oriented at various angles, enabling the device to adapt to different workpiece shapes and geometries while maintaining positioning accuracy through controlled movement along precision guides.
Solution Approach 2:
The measuring device incorporates movement in multiple spatial dimensions through its movable support structure. The support can translate along guides in different directions and rotate to achieve various orientations, adding dimensional flexibility that allows the same device to accurately position and measure workpieces of different shapes and sizes.

AI summary
The present invention relates to an accommodating apparatus for accommodating an object (5) of any desired shape, having a basic frame (1) and at least one first basic-carrier bearing (4a), which is arranged on the basic frame (1) and has two guides, on which at least one first basic carrier (6) is mounted on a first carrier-displacement unit (11a), which can be displaced via a first basic-carrier drive (6a), and a second basic carrier (6) is mounted on a second carrier-displacement unit (11a), which can be displaced via the first basic-carrier drive (6a) or via a second basic-carrier drive (6a). A third basic carrier (6), which is arranged on a third carrier-displacement unit (11a), can be displaced on the first basic-carrier bearing (4a) by a third basic-carrier drive (6a), by the first basic-carrier drive (6a) or by the second basic-carrier drive (6a), or the third basic carrier (6) is arranged on a third carrier-displacement unit (11a), by way of a second basic-carrier bearing (4a) arranged on the basic frame (1) and having two rails, and can be displaced by the third basic-carrier drive (6a). Each of the basic carriers (6) has arranged on it an intermediate-carrier bearing (4b), along which an intermediate carrier (19) can be displaced on the respective basic carrier (2), by an intermediate-carrier-displacement unit (11b), by means of an intermediate-carrier drive (6b). An attachment-carrier-displacement unit (11c) is arranged on the intermediate carrier (19) and makes it possible for an attachment-carrier bearing (4c) with an end-side tool holder (23) to be displaced by an attachment drive (6c).
