Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handling devices require multiple sensor systems for comprehensive monitoring, leading to increased design complexity and susceptibility to errors, particularly in accurately monitoring position accuracy and positional movements of held objects during processing.
Innovation Solution
A handling device with a sensor system comprising two interacting sensor components, where one sensor component is connected to the contact section and the other to the base section, allowing for the measurement of operating parameters such as displacement, force, and presence detection, thereby simplifying the monitoring process and reducing the need for multiple sensor systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensor systems are used for comprehensive monitoring, then measurement precision and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor functions into a single sensor system. The sensor device includes a first sensor component arranged on the contact section and a second sensor component arranged on the base section, which together measure displacement, presence, and force through their relative movements. This merging approach maintains comprehensive monitoring capability while reducing the number of separate sensor systems needed.
Solution Approach 2:
The sensor system is designed to perform multiple functions simultaneously. The same sensor components that detect displacement between the contact section and base section also enable presence detection and force measurement. This multi-functionality allows a single sensor system to replace what would traditionally require multiple specialized sensor systems.
2Reliability
If multiple sensor devices are arranged on the handling device, then comprehensive monitoring of operating parameters is achieved, but susceptibility to errors increases
Solution Approach 1:
The patent reduces the number of sensor devices by combining multiple monitoring functions into a single integrated sensor system. The first and second sensor components work together to provide comprehensive monitoring of displacement, presence, and force, thereby reducing susceptibility to errors associated with multiple separate sensor systems while maintaining reliable monitoring.
3Measurement precision
If sensor components are arranged to directly contact the object, then measurement precision is improved, but the risk of object interference and error increases
Solution Approach 1:
The patent introduces the contact section as an intermediary between the object and the first sensor component. The first sensor component is arranged on the contact section rather than directly contacting the object. This intermediary structure allows the sensor to measure displacement and position accurately while being protected from direct object interference, contamination, and damage.

AI summary
The invention relates to a handling device (10) for holding objects (12) comprising a base section (22) and a contact section (20), and a sensor device (26) comprising a first sensor component (28) and a second sensor component (30) which cooperate to determine operating parameters of the handling device (10). The sensor device (26) is configured to detect a change in the position of the first sensor component (28) relative to the second sensor component (30), wherein the first sensor component (28) is designed and arranged such that when an object (12) rests against and is held against the contact section (20), a displacement of the object (12) relative to the base section (22) is associated with a displacement of the first sensor component (28) relative to the base section (22), and wherein the second sensor component (30) is arranged in a fixed position relative to the base section (22).The invention also relates to a method for monitoring a handling process with a handling device.
