Solution Overview
Problem
Conventional weighing apparatuses fail to accurately identify and correct for environmental variations, leading to uncertainty in measurement accuracy and user anxiety regarding the source of performance issues, whether due to the installation environment or the apparatus itself.
Innovation Solution
A weighing apparatus equipped with a load measuring mechanism, environmental measurement means, storage, and arithmetic processing units that correlate and display temporal fluctuations in weighed and environmental data, allowing users to visually recognize and understand the impact of environmental variations on measurement results, thereby attributing performance issues to environmental factors and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If environmental factors are monitored and correction values are applied during calibration, then measurement accuracy is improved, but users cannot understand the correlation between environmental variations and measurement results
Solution Approach 1:
The system provides visual feedback by displaying graphs that show the correlation between environmental factor variations and measurement result fluctuations. This allows users to see how environmental changes affect weighing accuracy, transforming invisible environmental impacts into visible information that helps users understand and address the root causes of measurement deviations.
Solution Approach 2:
The patent introduces an intermediary visualization system (display device showing graphs) that mediates between the environmental monitoring data and user understanding. This intermediary translates complex environmental data and measurement results into an intuitive visual format that reveals correlations, allowing users to comprehend the relationship between environmental variations and measurement accuracy without needing to analyze raw data themselves.
2Measurement precision
If calibration is performed multiple times under varying environmental conditions, then correction values are updated, but fundamental performance is not achieved unless environmental variations settle
Solution Approach 1:
The system performs preliminary analysis by visually displaying the correlation between environmental variations and measurement results before performing calibration. This allows users to determine whether environmental factors are causing measurement deviations, enabling them to wait for environmental stabilization or take corrective actions before calibration, thereby avoiding repeated unnecessary calibration attempts and saving time.
Solution Approach 2:
The system empowers users to self-diagnose the cause of measurement accuracy issues by providing visual correlation data. Users can independently determine whether environmental variations are affecting weighing accuracy without requiring technical support or repeated calibration attempts, allowing them to make informed decisions about when to perform calibration and how to improve their measurement environment.
3Ease of operation
If environmental measurement data are displayed as allowable value evaluations, then users are urged to correct values, but users cannot recognize how much installation environment affects weighing
Solution Approach 1:
The patent adds a new dimension to environmental data presentation by displaying not only whether environmental values are within allowable ranges but also how these variations correlate with measurement result fluctuations over time. This temporal and correlational dimension transforms static compliance checks into dynamic insights about environmental impact magnitude, allowing users to understand both the presence and quantitative effect of environmental factors on weighing accuracy.

AI summary
[Object] To provide a weighing apparatus by which it is possible for a user himself/herself to determine poor performance of the apparatus is a factor attributable to an installation environment, to reduce anxiety in use by the user, allowing the user to use the apparatus with confidence including understanding error factors by environment, and the weighing accuracy is improved from a new perspective. [Solution] The apparatus is configured such that respective temporal fluctuations in weighed data detected from a load measuring mechanism 2 and environmental measurement data detected in an environmental measurement means 10 are recorded in a correlative manner in an arithmetic processing unit 32, and the temporal fluctuations are visually recognizable via a display unit 31. Thereby, the correlation between the environmental variations and the weighed data, which has not conventionally become apparent, is visually disclosed, and it is possible for a user to easily recognize that poor performance of the apparatus attributable to the environmental variations, that increases the reliability of the weighing apparatus. Further, the fundamental performance (accuracy) presented by the apparatus is also assured by allowing the user himself/herself to improve the surrounding environment.
