Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment of curved elbow fittings is performed, then the hose line can be assembled, but the alignment is cumbersome, time-consuming, and imprecise
Solution Approach 1:
The patent introduces an auxiliary device with a reference plane and angle setting device as an intermediary tool between the manual operator and the elbow fittings. This device provides a standardized reference framework that mediates the alignment process, enabling precise angular positioning without requiring manual measurement and calculation, thus resolving the contradiction between alignment precision and assembly time
Solution Approach 2:
The patent replaces the manual mechanical alignment process with a standardized auxiliary device that incorporates reference planes and angle setting mechanisms. This substitution transforms the imprecise manual operation into a precise, repeatable process using the auxiliary device's built-in reference systems, thereby improving precision while reducing time loss
2Ease of operation
If manual alignment is used for obtuse angle elbow fittings, then assembly can proceed, but the plane of curvature is hardly recognizable and alignment is very difficult
Solution Approach 1:
The auxiliary device serves as an intermediary that provides a clear reference plane and standardized angle setting mechanisms. For obtuse angle fittings where the plane of curvature is difficult to recognize visually, the device's reference plane and angle scales act as mediators that make the alignment process straightforward and precise, directly addressing the ease of operation and measurement precision contradiction
Solution Approach 2:
The patent changes the measurement parameters by introducing a standardized reference plane and angle setting device with clear angular markings. This transforms the difficult visual estimation of obtuse angles into a precise parameter-based alignment process, where the angle is determined by setting the fitting relative to the reference plane rather than visual judgment, thereby improving both ease of operation and measurement precision
3Adaptability or versatility
If hose lines are bent away from natural curvature, then installation requirements can be met, but the hose tends to avoid this forced curvature causing non-parallel arrangement
Solution Approach 1:
The auxiliary device enables preliminary alignment of the elbow fittings to the hose's natural curvature before final installation. By using the reference plane to establish the correct angular relationship in advance, the hose can be installed in its natural curved state without forced bending, thereby maintaining both installation adaptability and hose parallelism
Solution Approach 2:
The auxiliary device creates a reference model (reference plane) that copies or replicates the hose's natural curvature characteristics. This reference plane serves as a template that guides the alignment of elbow fittings to match the natural curvature, allowing the hose to maintain its stable parallel arrangement while meeting installation requirements

AI summary
The device has an adjusting unit for adjusting a hose piece (2) based on a bending process, so that the piece lies in a hose datum plane (12) with its curved longitudinal axis. Another adjusting unit has an angle scale to adjust arc armatures (4) relative to the piece on a preset special rotary angle of armature bend plane (16) which is defined by a longitudinal axis (14) of the armatures, relative to datum plane.
