Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position detection devices require structural attachment to profile elements, which can lead to damage and are not space-efficient, especially when used with profile elements that need special retaining clips.
Innovation Solution
A position detection device with a profile element featuring central cavities and recesses that house measuring probes and positioning elements, allowing for secure, space-saving, and easy installation, with optional redundancy for error correction and dirt resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If position detection devices are attached to profile elements using special retaining clips, then the position detection function is achieved, but the device complexity and installation complexity increase
Solution Approach 1:
The patent integrates the position detection element directly into the profile element by utilizing the central cavity and recesses as built-in mounting features. The measuring probe is positioned within the central cavity while positioning elements engage with recesses, merging the detection function with the structural profile element itself rather than requiring separate attachment mechanisms.
Solution Approach 2:
The central cavity and recesses serve multiple functions: they provide structural support for the profile element, enable positioning of the measuring probe, and facilitate secure mounting of positioning elements. This multi-functional design eliminates the need for specialized retaining clips while achieving reliable position detection.
2Reliability
If a separate space is reserved on or near the profile element for position detection, then position detection is enabled, but the available space is reduced and structural attachment is required
Solution Approach 1:
The measuring probe is nested within the central cavity of the profile element, and positioning elements are nested within recesses. This nesting approach allows the position detection system to be housed within the existing profile structure without requiring additional external space.
3Stability of the object's composition
If structural attachment is used to mount position detection elements, then secure mounting is achieved, but the risk of damage increases
Solution Approach 1:
The profile element features locally optimized structures: a central cavity for housing the measuring probe and recesses for positioning elements. These localized features provide secure mounting at specific locations without requiring extensive structural modifications or heavy attachment hardware across the entire profile.
