Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional household scales lack an aesthetically pleasing design, require multiple user interactions for setup and operation, and do not offer customizable automated features for weight tracking and reminders.
Innovation Solution
A buttonless digital weight scale with a display screen and advanced recognition algorithms that allows users to interact through physical contact, enabling automated user identification, weight tracking, time and date stamping, and customizable reminders for medical and personal tasks, using a radio interface for atomic clock synchronization and an LCD screen for visual data representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If buttons and switches are added to the scale for user interaction, then the scale can perform more functions and be more versatile, but the aesthetic appearance and surface smoothness are compromised
Solution Approach 1:
The patent replaces mechanical buttons and switches with a touch-sensitive display screen interface. Users interact with the scale by touching the display screen, which eliminates the need for physical buttons while maintaining full functionality. This substitution preserves the smooth, buttonless aesthetic appearance while enabling versatile operations including weight measurement, user identification, and reminder setup.
2Ease of manufacture
If manual setup and operation steps are required for the scale, then the device is easier to manufacture with fewer automated components, but the user experience and convenience are reduced
Solution Approach 1:
The patent implements automated user identification through recognition algorithms that automatically detect and identify users based on their presence or biometric data. The scale also automatically timestamps weight measurements and manages multiple user profiles without manual configuration. These self-service features significantly improve user convenience while the modular architecture keeps manufacturing complexity manageable.
3Extent of automation
If automated features such as user identification and timestamping are implemented, then user convenience and operational efficiency are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent employs a microcontroller that serves multiple functions: weight measurement processing, user identification algorithms, timestamp generation, reminder management, and display control. By consolidating these diverse automated functions into a single multi-functional controller, the system achieves high automation levels while managing overall device complexity through functional integration rather than proliferation of separate components.
4Loss of information
If a display screen is added to the scale for information presentation, then the user interface and data visualization are enhanced, but the aesthetic simplicity and surface smoothness are compromised
Solution Approach 1:
The patent integrates the display screen directly into the scale's top surface, merging the information presentation function with the weighing platform. The display screen becomes an integral part of the smooth surface rather than a separate additive component. This integration allows the screen to be flush-mounted or seamlessly embedded, maintaining the aesthetic simplicity and surface smoothness while providing comprehensive information display capabilities for weight measurements and user feedback.
Data Source
AI summary
A digital scale includes a display and buttonless top platform. Contact with the scale platform alone allows a user to power the scale, identify a user of the scale, determine a mode of operation of the scale, and to establish a reminder. The scale has a first mode of operation displaying a reading of the user's weight. The scale has a second mode of operation providing a display of the user's current weight, a delta or differential weight with the most recent recorded weight measurement and if the data is available, additional deltas for weight measurements taken up to one year earlier. The scale has a third mode of operation in which it provides a reminder for tasks to be undertaken by a user within a specified time.
