Sensor Housing Clamping Geometry for Controlled Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current housing designs for electronic components, such as sensors, require complex manufacturing processes and permanent joining of parts, which can lead to excessive force application damaging the components and making maintenance difficult.
Innovation Solution
A housing design with a pre-tensioned lid featuring a clamping geometry, including a groove, ridge, and clamp web, that applies a controlled force within a specified range to securely affix the sensor while allowing for easy assembly and disassembly, using a polyamide or polymer material with adjustable elasticity and profile for optimal positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor is affixed using traditional caulking or welding methods, then the join between lid and lower part is permanent and stable, but the manufacturing process becomes complex and the sensor may be damaged by excessive force
Solution Approach 1:
The housing is divided into a lower part and a lid that can be separately assembled and disassembled. The sensor is retained in the lower part, and the lid is joined via a clamping geometry that allows for separation, enabling maintenance while maintaining operational stability.
Solution Approach 2:
The clamping force is controlled within a specified range to ensure the sensor is securely retained without exceeding maximum force limits that could damage the pressure-sensitive sensor. This parameter control resolves the contradiction between secure retention and sensor protection.
2Reliability
If the lid is permanently joined to the lower part using traditional methods, then the join is stable, but maintenance and repair become difficult
Solution Approach 1:
The housing is divided into a lower part and a lid that can be separately assembled and disassembled. The sensor is retained in the lower part, and the lid is joined via a clamping geometry that allows for separation, enabling maintenance while maintaining operational stability.
Solution Approach 2:
The clamping geometry provides a dynamic join that is stable during operation but can be easily separated when needed. The clamp web and ridge create a force-fit connection that maintains stability during use but allows for disassembly for maintenance purposes.
3Strength
If excessive force is applied when affixing the sensor, then the sensor is securely retained, but the pressure-sensitive sensor is damaged
Solution Approach 1:
The clamping force is controlled within a specified range to ensure the sensor is securely retained without exceeding maximum force limits that could damage the pressure-sensitive sensor. This parameter control resolves the contradiction between secure retention and sensor protection.
Solution Approach 2:
The lid is designed with pre-tensioning that distributes the clamping force evenly across the sensor and housing structure. This pre-engineered force distribution prevents localized excessive forces that could damage the sensor while maintaining secure retention.
4Reliability
If multiple manufacturing processes are used for housing assembly, then the join is permanent and stable, but the manufacturing time and complexity increase
Solution Approach 1:
The clamping geometry integrates the joining function into a single force-fit operation between the lid and lower part. The clamp web and ridge create both the mechanical connection and the force distribution in one integrated structure, eliminating the need for separate caulking or welding steps.
Solution Approach 2:
The housing is divided into a lower part and a lid that can be separately assembled and disassembled. The sensor is retained in the lower part, and the lid is joined via a clamping geometry that allows for separation, enabling maintenance while maintaining operational stability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures stable sensor positioning and functionality over the component's lifespan, with adjustable force application to prevent damage, and allows for easy removal and reassembly for maintenance purposes, simplifying the manufacturing process.
Implementation Method 1
the force with which the lid is attached to the electronic component is in particular adjustable by means of a specified elasticity module on the lid
Implementation Method 2
a clamp web is arranged on the lower part of the lid in such a manner that following the connection with the lower part, the lid is clamped to the lower part with a clamping force which acts in parallel to the force applied to the electronic component

AI summary
A housing for retaining an electronic component, including a lid and a lower part made of synthetic material, wherein the lid is joined in a force-fit manner to the lower part by clamping geometry, and in order to affix the electronic component in position, the lid applies a specified force (F) to the electronic component after being joined to the lower part due to its design. Here, the lid is designed in such a manner that the force (F) applied lies within a specified force range (B), and that the clamping geometry comprises a groove on the lower part and a ridge on the lid which grips into the groove, wherein a clamp web on the lower part or on the lid is arranged in such a manner that the lid is removably clamped to the lower part after being joined to the lower part with a force (F) which acts parallel to the clamping force (KF).
