Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary insert units with flow rate regulators lack improved control behavior and are often limited by circular cross-sections, which restrict their design flexibility and efficiency.
Innovation Solution
A ring-shaped throttle body divided into two first ring sections and two curved second ring sections, integrated with a flow rate regulator in a rectangular insert housing, allows for elastic deformation and improved control behavior, enabling a flat and narrow design with enhanced support surface and pressure resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a circular cross-section is used for the insert housing, then the design is simpler and more conventional, but the design flexibility and efficiency are restricted
Solution Approach 1:
The insert housing is designed with a rectangular cross-section instead of the conventional circular shape. This asymmetric design allows the long sides to be oriented in the direction of water flow, providing better flow guidance and reduced turbulence. The rectangular geometry enables improved design flexibility and efficiency while maintaining structural simplicity.
2Strength
If a bar or cord shaped throttle body is used, then the structure is simple, but the support surface is limited and pressure resistance is reduced
Solution Approach 1:
The throttle body is designed with a ring shape featuring curved second ring sections that connect the first ring sections. This curved geometry provides a larger support surface area compared to a straight bar or cord shape, significantly improving pressure resistance. The ring configuration allows the throttle body to better withstand water pressure while maintaining structural simplicity.
3Ease of operation
If the throttle body is made elastic and deformable, then the control behavior is improved and flow rate regulation is enhanced, but the structural stability may be compromised
Solution Approach 1:
The throttle body is manufactured from elastic material that allows it to deform under water pressure. This flexibility enables the throttle body to automatically adjust its position and shape in response to pressure changes, improving control behavior and flow rate regulation. The elastic properties allow the throttle body to maintain optimal positioning without compromising structural integrity.
4Productivity
If a rectangular cross-section is used for the insert housing, then the design flexibility and efficiency are improved, but the manufacturing complexity increases
Solution Approach 1:
The insert housing is designed as a modular unit with a rectangular cross-section that can be manufactured as a single integrated component. The segmentation principle is applied to the throttle body, which is divided into first ring sections and second ring sections, allowing for simplified manufacturing while maintaining the overall rectangular housing structure. This approach balances manufacturing ease with design efficiency.

Function Achieved in This Case
The solution provides improved control behavior and design flexibility, ensuring a fixed maximum water flow rate independent of pressure, while shaping the water into a non-splashing, homogeneous flat jet or jet band.
Implementation Method 1
the throttle body under the pressure of the medium flowing through so elastically ver is formable that the clear flow cross section of the control gap narrows by molding the throttle body into the profiling of the at least partially profiled wall

AI summary
The invention relates to a sanitary insertion unit (1) with an insertion housing (2) that can be inserted into the water outlet of a sanitary outlet fitting. A flow regulator is provided in the insertion housing (2) of the insertion unit (1), which has at least one flow channel through which water flows, and in which flow channel a throttle element (8) is arranged. The flow regulator used in the insertion unit (1) has at least one control gap, which is arranged between a wall that is profiled at least partially and delimits the flow channel, and an adjacent outer surface of the throttle element (8).The throttle body (8) made of elastic material is ring-shaped and is held in the insertion unit in such a way that the ring-shaped throttle body (8) is divided in its longitudinal extent into two longitudinally oriented first ring sections (9, 10) and two curved second ring sections (11, 12) connecting the first ring sections (9, 10) on both sides (see Figure 4).
