Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the actuating element is arranged to be linearly movable with parallel axes to the valve closing element, then the outlet fitting can be designed to be particularly slim, but the complexity of the actuating mechanism increases
Solution Approach 1:
The actuating element and valve closing element are merged into a single linear motion system with parallel axes, eliminating the need for separate actuating and closing mechanisms. This integration allows the outlet fitting to achieve a slim design while maintaining functional complexity through a unified actuation system.
Solution Approach 2:
The invention transitions from traditional perpendicular or intersecting axis arrangements to a parallel axis configuration, utilizing dimensional reorientation to achieve a more compact, slim profile while preserving the necessary valve control functionality through linear motion in a optimized spatial arrangement.
2Ease of operation
If the actuating element is made accessible for manual operation, then the ease of operation is improved, but the compact design is compromised
Solution Approach 1:
The outlet pipe body is provided with a localized recess at the actuation position, creating an accessible area for manual operation without increasing the overall dimensions of the fitting. This local modification allows easy access to the actuating element while preserving the compact, slim design of the main body.
Solution Approach 2:
The actuating element is nested within or adjacent to the recess in the outlet pipe body, allowing it to be accessible for operation while being integrated into the compact structure. The recess provides the necessary access space without requiring the actuating element to protrude significantly from the main body.

AI summary
2.1. The invention relates to a sanitary outlet fitting with a fitting housing (1) comprising a longitudinally extended outlet pipe body (2), a fluid inlet (3) into the outlet pipe body (2), a first and a second outlet (4, 5) from the outlet pipe body (2), a first fluid connection (6) from the fluid inlet (3) to the first outlet (4) and a second fluid connection (7) from the fluid inlet (3) to the second outlet (5), a valve (8) with a valve closing element (9) which is linearly movable in the outlet pipe body (2) between a first and a second setting position (E1, E2) and is configured for selectively closing and opening the first and/or the second fluid connection (6, 7), and an actuating unit (10) with an actuating element (11) arranged on the outlet pipe body (2) for actuating the valve closing element (9). 2.2.According to the invention, the actuating element (11) is arranged to be linearly movable, and an axis of movement (BB) of the actuating element (11) and an axis of movement (Bv) of the valve closing element (9) run essentially parallel to each other and essentially parallel to a longitudinal axis (LA) of the outlet pipe body (2). 2.3. Use, e.g., as a bathtub outlet fitting.
