Optoelectronic Sensor Knob Encoder Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optoelectronic sensors face challenges in setting operating parameters with required sensitivity due to the limitations of multiturn trimmers, which increase costs and dimensions, and require additional visual indicators, complicating production and design.
Innovation Solution
The use of a multiturn encoder with configurable parameters for adjusting operating parameters, such as trigger threshold and cut-off distance, allows for precise sensitivity adjustments without additional visual indicators, using a single knob for multiple settings and reducing component complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiturn trimmers are used for adjusting operating parameters, then the sensitivity and precision of parameter setting is improved, but the device dimensions and production costs increase
Solution Approach 1:
The patent replaces mechanical multiturn trimmers with an electronic encoder system that uses electronic signals and software processing to achieve the same parameter adjustment function. This substitution eliminates the need for complex mechanical components while maintaining or improving adjustment precision.
Solution Approach 2:
The encoder is designed to serve multiple functions: it provides precise parameter adjustment, displays adjustment status through integrated visual indicators, and communicates with external systems. This multi-functionality consolidates what would otherwise require separate components into a single unit.
2Ease of operation
If additional visual indicators are added to show parameter settings, then the ease of operation is improved, but the device complexity and production costs increase
Solution Approach 1:
The patent combines the visual indication function with the existing encoder component. The encoder incorporates integrated visual indicators that display parameter settings and adjustment status, eliminating the need for separate indicator components while providing comprehensive feedback to the operator.
Solution Approach 2:
The encoder serves multiple functions simultaneously: precise parameter adjustment through rotation, visual display of settings through integrated LEDs, and communication with external systems. This multi-functionality reduces the total component count while improving operational ease.
3Ease of manufacture
If standard components are used instead of specialized trimmers, then the ease of manufacture is improved, but the measurement precision of parameter adjustment may worsen
Solution Approach 1:
The patent replaces specialized mechanical trimmers with standard electronic encoders that are widely available and easier to manufacture. The encoder's electronic nature allows for precise parameter adjustment through software control while using standardized hardware components.
Solution Approach 2:
The encoder allows for flexible parameter configuration through software, enabling the same hardware component to achieve different levels of precision depending on the application requirements. This adaptability maintains measurement precision while using standard components.

AI summary
An optoelectronic sensor for detecting one or more features of an object comprises means for controlling the operation of said sensor and a face (20) for interaction with an operator provided with adjusting means (22, 23) for adjusting operating parameters of the sensor. The means for controlling is connected to the adjusting means (22, 23) to detect a setting of the operating parameters and the adjusting means (22, 23) comprises a knob (22) which is rotatable around an axis (A) for adjusting at least one predetermined parameter among said operating parameters. The sensor comprises a multiturn encoder (28) that is actuatable by the knob (22) and the means for controlling are connected to the multiturn encoder (28) to obtain a rotation mode of said knob, for example a rotation direction and further/or a rotation speed, so as to associate with said detected rotation mode a corresponding setting mode of the predetermined parameter, for example a setting with a first coarse sensitivity, or a second fine sensitivity.
