Scale Control Button for Pourable Bulk Materials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scale control systems for pourable materials are complex and difficult for untrained operators to use, requiring specific button sequences and operations to accurately measure and record material weights during loading and unloading.
Innovation Solution
A simplified scale control method where a single control button, such as the START/STOP button, transitions the system through modes for TARE, UNLOAD, and PRINT functions, displaying net weight changes and automatically saving data, with optional features like power control and data field display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional scale control systems use multiple control buttons and complex sequences to accurately measure and record material weights, then measurement precision is improved, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines multiple control functions (TARE, PRINT, Gross/Net display switching) into a single control button. The single button cycles through different operational modes sequentially, eliminating the need for multiple separate buttons and complex operation sequences while maintaining accurate weight measurement and recording capabilities
Solution Approach 2:
The single control button serves multiple functions depending on the current operational mode. The same button performs TARE initialization, triggers PRINT to save data, and switches display between Gross and Net weights. This multi-functionality reduces the number of physical controls needed while preserving all necessary measurement and recording operations
2Adaptability or versatility
If conventional scale control systems use multiple control buttons and sequences, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple control functions into a single button interface. The control button cycles through different operational states (TARE mode, PRINT mode, Gross/Net switching) based on sequential presses, thereby maintaining full functionality while dramatically simplifying the physical control structure
Solution Approach 2:
The control button's function dynamically changes based on the current operational mode and sequence of presses. The system transitions between different states (initialization, weighing, printing, display switching) using the same physical button, making the control system adaptive rather than static

AI summary
A method of controlling a scale in connection with to a carrier of pourable bulk materials. The scale involved has a control with a display and control buttons. Upon a first press of a first control button, the system is transitioned into a “tare” mode and displays a base, or tare, value. Upon a second press of the first control button, generally after unloading some or all of the load, the difference in weight from the first press is saved to a storage medium, and a value displayed representing the weight of bulk material in the container at that time. The method may also include the pressing of a Zero button to zero the scale before the carrier is first loaded.
