Optoelectronic Measuring Device Single-Face Scale Fixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optoelectronic measuring devices with hollow profiles require separate access for fixing the graduated scale and the profile, making installation cumbersome, especially in environments where not all faces are accessible.
Innovation Solution
The optoelectronic measuring device allows both the scale fixing device and the profile fixing device to be accessible from the same face of the hollow profile, enabling simultaneous immobilization of the graduated scale and fixing of the profile to an object with a single actuation, without the need for holes in the graduated scale.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate access for fixing the graduated scale and the profile is required, then the fixing operation can be performed, but the installation process becomes cumbersome and complex
Solution Approach 1:
The patent combines the access points for the scale fixing device and profile fixing device into a single face of the hollow profile. This merging of access requirements eliminates the need for separate access operations, simplifying the installation process while maintaining the integrity of both fixing mechanisms.
2Reliability
If multiple actuations are required to immobilize the graduated scale, then the scale can be secured in both measuring directions, but the operation becomes more complex and time-consuming
Solution Approach 1:
The scale fixing device is designed with a cam mechanism that automatically exerts pressure on the graduated scale in the anchoring direction when the elongated element is actuated in the scale fixing direction. This preliminary action ensures that both immobilization functions are achieved with a single actuation, improving ease of operation while maintaining reliable immobilization.
3Reliability
If holes are made in the graduated scale for immobilization, then the scale can be secured, but the structure of the graduated scale becomes more complex
Solution Approach 1:
The patent extracts the immobilization function from the graduated scale structure itself and relocates it to the scale fixing device. The scale fixing device with its cam mechanism and pressure-exerting elements provides the immobilization function externally, eliminating the need for holes or modifications to the graduated scale structure.

AI summary
The invention relates to a device (100) configured for measuring the relative position between two objects, one of the objects being movable with respect to the other object along a longitudinal axis (X). The device (100) comprises a graduated scale (3), a hollow profile (4) defining an inner cavity and a channel (4.0) arranged in said inner cavity, extending in the longitudinal axis (X) and being configured for housing the graduated scale (3), a scale fixing device for immobilizing the graduated scale (3) in the hollow profile (4) in both measuring directions (A1, A2) along the longitudinal axis (X), and a profile fixing device for fixing the hollow profile (4) to one of the objects (1). Both fixing devices are accessible from the same face of the hollow profile (4) to perform the corresponding fixing operation.
