Impact Sensor Radial Hose Opening Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impact sensors for motor vehicles require additional work steps and components for secure fastening, such as clamping devices or cable ties, which complicate installation and increase costs, particularly in tight spaces.
Innovation Solution
The impact sensor design incorporates radially outward openings in the hose for easy penetration of fastening means, with options for press fits, undercuts, or separate fastening parts, allowing for secure attachment without additional components like cable ties, and enabling tolerance compensation during assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping devices or cable ties are used to secure the hose to the connecting piece of pipe, then secure fastening is achieved, but additional work steps and components are required, complicating installation and increasing costs
Solution Approach 1:
The patent integrates the fastening function directly into the hose structure by incorporating a radially outward opening that receives a fastening means. This merging of the connection interface into the hose itself eliminates the need for separate clamping devices or cable ties, thereby securing fastening while reducing installation complexity and component count
Solution Approach 2:
The hose is segmented with a radially outward opening that creates a dedicated interface for the fastening means. This segmentation allows the fastening function to be integrated into the hose structure without requiring additional external components, simplifying both the device and installation process
2Reliability
If clamping devices or cable ties are used to secure the hose, then secure fastening is achieved, but installation time and costs increase
Solution Approach 1:
The radially outward opening is pre-formed in the hose during manufacturing, allowing the fastening means to be directly inserted during assembly without requiring additional work steps. This preliminary preparation of the connection interface significantly reduces installation time while maintaining secure fastening
Solution Approach 2:
By integrating the fastening interface directly into the hose structure through the radially outward opening, the patent eliminates the need for separate fastening components and their associated installation steps, thereby reducing installation time while ensuring reliable connection
3Reliability
If additional fastening components like cable ties are used, then secure attachment is achieved, but installation space requirements increase
Solution Approach 1:
The patent merges the fastening function into the hose structure itself through the radially outward opening, eliminating the need for external cable ties or clamping devices. This integration maintains secure attachment while significantly reducing the space required for installation, making it ideal for tight vehicle compartments

AI summary
A further development of an impact sensor is described, consisting of a hose (1) that is elastically deformable upon impact and has a cavity, and at least one pressure sensor for detecting the pressure change in the cavity of the hose. The pressure sensor has a connecting tube (2) on its housing, over which an overlapping section of the hose (1) is pushed. In the overlapping section of the hose (1), at least one radially outwardly directed opening (11) is provided, spaced apart from the edge (13) of the hose, along with a fastening element (21, 22, 3) for penetration into the opening (11). This fastening element can be a locking lug (21) on the connecting tube (2), which is shaped according to the opening (11), or a separate fastening part 3, which is inserted into the opening 11 from the outside of the hose.By forming a head, by gluing, locking, hot forming or laser fusing, a strengthening and inseparable connection can be achieved.
