Non-linear Progress Arc for Smart Recipe Weighing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive on-screen weighing for recipes lacks intuitive and accurate perceptual cues, making it difficult for users to accurately measure ingredient weights.
Innovation Solution
A computer-implemented method using a weighing mechanism connected to a weighing application that determines a target weight, calculates a non-linear progress arc angle based on the current and target weights, and displays this on a user interface to provide visual feedback, allowing users to intuitively track weight progress and ensure accuracy within a target range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a linear weight indicator is used, then the display is simple and easy to understand, but it does not provide sufficient perceptual cues for accurate weighing
Solution Approach 1:
The patent applies curvature by using an arc-shaped progress indicator instead of a linear one. The arc provides perceptual cues through its curved geometry, making it easier for users to perceive weight progress and achieve target weights accurately. The curved arc creates natural visual flow and perceptual landmarks that aid in accurate ingredient weighing.
2Productivity
If the weight indicator moves at constant speed, then the display is simple to implement, but it does not help users slow down near the target weight
Solution Approach 1:
The patent implements dynamic behavior by making the arc progress speed variable rather than constant. The arc accelerates when the ingredient weight is far from the target and decelerates as it approaches the target weight. This dynamic speed adjustment helps users naturally slow down their pouring action, preventing overpouring and improving measurement precision near the target.
3Loss of information
If no visual feedback mechanism is provided, then the interface is simpler, but users cannot intuitively track weight progress
Solution Approach 1:
The patent implements a visual feedback mechanism using an arc that dynamically responds to weight changes. As ingredients are added, the arc progresses toward a target position, providing continuous visual feedback on weight progress. This feedback loop helps users understand how close they are to the target weight and adjust their pouring accordingly, improving both visibility of progress and measurement accuracy.

AI summary
A computer-implemented method, using a weighing mechanism operatively connected to a weighing application. The method includes drawing a progress arc on a user interface of the weighing application, where the drawing is based on a non-linear function of the target weight (Wt) for the particular ingredient, a total angle to be drawn when the target weight (Wt) has been met, and the current weight (w) of the particular ingredient.
