Electronic Scale Profile Determination and Redundancy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of measuring results from electronic scales with integrated computers is heavily dependent on the user's attention and technical qualifications, leading to potential errors and faulty operations due to the complexity of parameter settings and protocols.
Innovation Solution
The system implements a redundancy control mechanism for profile determination and execution, where users are guided through successive steps with relevant options, and confirmation of each action is required before proceeding, using a combination of manual and automatic confirmation methods, with optional authorization checks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are allowed to manually set parameters and activate profiles, then the scales can perform complex weighing operations, but the quality of measuring results becomes heavily dependent on user attention and technical qualifications
Solution Approach 1:
The system performs preliminary actions by automatically determining the appropriate profile and executing the weighing protocol before the user can make errors. The computer identifies the weighing type, selects the corresponding profile, and guides the user through predefined steps, eliminating the need for users to manually configure complex parameters and reducing dependency on user expertise.
2Adaptability or versatility
If the scales provide extensive parameter settings and protocol options, then more weighing operations can be performed, but the complexity of instrumentation increases leading to faulty operations
Solution Approach 1:
The computer system performs self-service by automatically determining the weighing type, selecting the appropriate profile from stored protocols, and guiding the user through the necessary steps. This automation reduces the effective complexity presented to the user while maintaining access to extensive weighing operation capabilities through the background intelligence of the system.
3Reliability
If users must follow detailed protocols step by step, then accurate measurements can be obtained, but the time required for setting parameters and performing operations increases
Solution Approach 1:
The system performs preliminary actions by pre-configuring profiles with optimal parameter settings and protocol steps based on different weighing types. When a user initiates a weighing operation, the computer automatically retrieves the appropriate profile and guides the user through pre-validated steps, eliminating the time-consuming manual configuration phase while maintaining measurement accuracy through protocol adherence.

AI summary
Electronic scales having an integrated computer including a display for presenting information to a user, an input unit for entering selection data by a user, a memory for storing a plurality of activatable profiles as sets of parameter values for assignment to corresponding sets of parameters, and a data processing unit for controlling the display, the input unit, and the memory, and for determining and processing measured values in accordance with the current activated profile. The measured values are generated during a weighing operation by the user. To determine a profile, a user is requested, over a plurality of successive steps, to select one of several options presented by the display, the combination of the options presented in a step being dependent on the selection made in the preceding step. Then, during the weighing operation, the user is requested, again, over a plurality of successive steps, to perform an action presented by the display. A request, is a function of the type of actual current activated profile, and is made only if the action requested in the preceding step is confirmed as carried out.
