Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor fastening devices are complex and expensive to manufacture due to the need for clamping jaws and intricate adjustments, limiting their production efficiency and flexibility.
Innovation Solution
A sensor mounting device with a one-piece sleeve featuring internal threads, where the sleeve is embedded in a housing with formed collars that secure it through reshaping, eliminating the need for clamping jaws and allowing for simpler, cost-effective production and flexible installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamping jaws and intricate adjustments are used to secure the sleeve, then the sensor fastening device achieves reliable fixation, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The invention extracts and eliminates the clamping jaws and adjustment mechanisms from the sensor fastening device. Instead of using these complex components to secure the sleeve, the patent uses a simple insertion method where the sleeve is pushed through the housing and fixed in place, thereby achieving reliable fixation without the manufacturing complexity and cost associated with clamping jaws and adjustments.
Solution Approach 2:
Instead of using active components like clamping jaws to grip and secure the sleeve, the invention inverts the approach by using a passive form-fitting connection. The sleeve is designed with collars that match recesses in the housing, creating a self-retaining structure that eliminates the need for active fastening mechanisms.
2Reliability
If clamping jaws and adjustment mechanisms are incorporated, then the sensor fastening device provides secure mounting, but the production time and cost increase
Solution Approach 1:
The collars on the sleeve are pre-formed during the sleeve manufacturing process, before insertion into the housing. The housing recesses are also pre-formed. This preliminary preparation allows for rapid assembly by simple insertion, eliminating the need for time-consuming adjustments and securing operations during final assembly, thereby significantly improving production efficiency.
3Strength
If the sleeve is secured using traditional fastening methods, then the connection is robust, but the device requires complex adjustments and alignment
Solution Approach 1:
The sleeve and housing are designed with self-aligning features through the form-fitting connection between collars and recesses. When the sleeve is inserted, the collars automatically align with the recesses and engage, providing robust connection without requiring external alignment tools or complex adjustment procedures. The design itself performs the alignment function.
4Productivity
If injection molding process is used for the housing, then production is efficient, but the threaded sleeve requires complex adjustment and larger wall thickness
Solution Approach 1:
The invention segments the fastening function into separate components: the housing (produced by injection molding) and the sleeve with integrated collars. This segmentation allows the housing to be efficiently produced by injection molding while the sleeve incorporates the fastening features independently, eliminating the need for complex adjustments and allowing for smaller wall thickness in the housing.

AI summary
The sensor fastening device (1) has a housing (10) with an upper side (20) and a rear side (30), where a through opening (40) is formed in the housing. A sleeve is provided with an internal thread (80) with two ends for receiving a sensor, where the sleeve (70) is embedded in the through opening. The sleeve is formed in one piece, where the former end of the sleeve has a collar (90), which is embedded on the upper side of the housing by inserting in a recess (50). An independent claim is also included for a method for manufacturing a sensor fastening device.
