Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple digital display screen with memory is provided, then weight readings can be stored, but there is no easy way for a given user to uniquely identify themselves
Solution Approach 1:
The device segments user identification into separate functional elements: a display screen showing user names, tactile buttons for selection, and memory for storing user profiles. This segmentation allows users to easily identify themselves through visual and tactile cues without requiring complex authentication mechanisms.
Solution Approach 2:
The device enables self-service user identification by displaying user names on the screen and allowing users to press buttons corresponding to their names. The system automatically retrieves and displays weight data for the selected user from memory, eliminating the need for manual data entry or complex identification procedures.
2Measurement precision
If weight readings are taken without stability assessment, then measurement speed is fast, but accuracy is compromised when users cannot stand still
Solution Approach 1:
The device continuously monitors weight readings and provides feedback by displaying the current measurement on the screen. It automatically assesses stability by comparing consecutive readings and only finalizes the measurement when stability criteria are met, ensuring accuracy without requiring manual intervention or excessive measurement time.
Solution Approach 2:
The system changes the parameter of measurement finalization from immediate to conditional based on stability assessment. It monitors weight fluctuations and determines when to accept a reading based on predefined stability parameters, allowing fast measurement for stable users while ensuring accuracy for unstable users without time loss.
3Adaptability or versatility
If multiple users are supported with configurable buttons, then user-specific weight data can be stored, but device complexity increases
Solution Approach 1:
The device achieves multi-functionality by using a single set of configurable buttons and display screen to serve multiple users. The memory stores profiles for multiple users, and the same button interface allows any user to select themselves and access their data, eliminating the need for separate interfaces for each user.
Solution Approach 2:
The system creates digital copies of user profiles and weight data in memory. Each user has a unique profile stored as data, allowing the device to distinguish between users through software-based identification rather than physical differentiation, thus maintaining simplicity while supporting multiple users.
4Stability of the object's composition
If weight readings are not averaged over time, then response time is fast, but stability of the reading is compromised for users with imbalance
Solution Approach 1:
The device continuously takes weight readings and compares them against stability criteria without interruption. It maintains continuous monitoring until the required number of stable readings are obtained, ensuring reading stability for users with imbalance while minimizing total measurement time through efficient continuous processing rather than repeated discrete measurements.
