Method for evaluating an assembly area, system for performing the method and assembly area

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses a method and system for evaluating the effectiveness of an assembly or workstation area by segmenting the assembly process into identifiable steps marked by characteristic operation results (such as picking up a part or using a tool). Sensors automatically record the time when each key event happens, and the time intervals between steps are analyzed. This data is compared against reference data to objectively measure and improve the efficiency of assembly stations, either during simulation or real operation. The system is designed to use simple and cost-effective sensors and can be applied to existing or new workstations.

Use CasesContent extracted from patent full text and abstract with AI.

• Optimizing the layout and workflow of manual assembly workstations in manufacturing plants.
• Evaluating different workstation designs during the planning phase to determine the most efficient setup.
• Continuous improvement of existing assembly stations by identifying process bottlenecks or inefficiencies.
• Comparing the performance of alternative tools or arrangements in a production environment.
• Supporting ergonomic assessments by understanding task durations and frequencies.
• Implementing quality control processes by tracking and documenting production steps for traceability.
• Setting and validating standard performance metrics (e.g., for labor or process time calculations).

BenefitsContent extracted from patent full text and abstract with AI.

• Provides an objective, data-driven method for analyzing and improving workstation efficiency rather than relying on subjective observation.
• Uses simple and inexpensive sensors, reducing system cost and complexity compared to comprehensive motion tracking solutions.
• Minimizes data collection to only key events, making analysis and storage straightforward and efficient.
• Allows easy comparison between current performance and target/reference times for rapid identification of weak points.
• Can be implemented on both existing and new assembly areas, offering flexible deployment.
• Facilitates anonymized data collection to protect worker privacy and meet legal regulations.
• Enables wireless configuration and data transmission, simplifying integration in various production environments.
• Supports iterative process improvements, as repeated measurements and averaging filter out one-off anomalies.
• Integrates with common computer systems for analysis, reducing additional equipment investments.

Patent Abstract

The method involves dividing mounting process into individual process segments, which are identified by a characteristic operation result. A time point, during occurrence of the operation result, is recorded, during implementation or simulation of the mounting process at the process segments. Temporal gap between the recorded time point of subsequent process segments are determined and stored as a data set, which is derived for evaluation of effectiveness of a mounting place (3) in an evaluation unit (11). A determined data set is compared with a pre-determined reference data set. An independent claim is also included for a system for implementing the method for testing the mounting place.
