Solution Overview
Problem
Existing scanning assemblies face challenges in precisely positioning the radiation source relative to the carrier and lens, affecting the collimation and operation of the scanning assembly.
Innovation Solution
The scanning assembly incorporates a guide system comprising conductor elements and connection elements that allow the radiation source to be moved along an adjustment path for precise positioning, maintaining electrical contact and enabling easy alignment with the lens and scanning plate, with optional mechanical guidance within a receptacle on the carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radiation source is fixed rigidly on the carrier, then the electrical connection is stable, but the positioning precision and adjustability are poor
Solution Approach 1:
The patent transforms the static fixed connection into a dynamic adjustable connection. The radiation source can be positioned at different locations along the conductor track, allowing dynamic adjustment of the distance between the radiation source and lens while maintaining continuous electrical contact through the flexible conductor element.
Solution Approach 2:
The patent enables parameter changes by allowing the radiation source position to be adjusted along the adjustment path. This changes the critical parameter of distance between the radiation source and lens, optimizing collimation performance without requiring a completely new device design.
2Manufacturing precision
If the distance between radiation source and lens is adjusted for precise collimation, then the collimation quality improves, but the assembly complexity increases
Solution Approach 1:
The conductor element serves multiple functions: it provides electrical connection, enables positioning adjustment, and acts as a guide for the radiation source. This multi-functionality reduces the need for separate adjustment mechanisms, thereby reducing assembly complexity while maintaining precise collimation capability.
Solution Approach 2:
The flexible conductor element acts as an intermediary that mediates between the need for stable electrical connection and the need for adjustable positioning. It allows the radiation source to move along a defined path while maintaining continuous electrical contact, simplifying the overall assembly process.
3Ease of operation
If the radiation source is repositionable on the carrier, then the adjustability and alignment ease improve, but the electrical connection stability may deteriorate
Solution Approach 1:
The patent uses a flexible conductor element that can bend and deform to accommodate the movement of the radiation source along the adjustment path. This flexibility maintains continuous electrical contact throughout the adjustment range, ensuring connection stability is not compromised by the repositioning capability.

AI summary
The component (11) has a radiation source (4) i.e. LED, fixed on a holder and emitting electromagnetic radiation to scan a measurement graduation (50) of a position measuring system. Electrical conductor elements of the holder and electrical connection elements of the radiation source form a guide. The radiation source is moved on the guide along an adjustment trajectory relative to the holder while maintaining electrical contact between the connection elements and the conductor elements to arrange the radiation source at different positions along the trajectory on the holder. The electrical conductor elements are formed as strip conductors.
