Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If press-sensing touch screens are used for weight measurement, then weight measurement capability is achieved, but measurement precision and measuring range are limited
Solution Approach 1:
A dedicated sensing member is introduced as an intermediary between the platform and the mobile device's touch screen. This sensing member has a sensing surface that contacts the touch screen, allowing the touch screen to detect weight-induced displacement with enhanced precision. The sensing member acts as a mediator that translates mechanical weight into detectable touch screen signals, overcoming the limitations of direct touch screen sensing.
2Measurement precision
If a dedicated scale device is used, then measurement precision is improved, but device portability and ease of operation are reduced
Solution Approach 1:
The invention enables the mobile device to serve multiple functions: it acts as both a computing device and a precision weighing scale. By integrating the sensing member with the mobile device's existing touch screen, the device gains weight measurement capability without requiring a separate dedicated scale device. This multi-functionality maintains portability and ease of operation while achieving accurate weight measurements.
3Device complexity
If the sensing member directly contacts the platform, then structural complexity is reduced, but measurement reliability is compromised
Solution Approach 1:
The sensing member serves as an intermediary component between the platform and the mobile device's touch screen. It includes a sensing surface that contacts the touch screen and a supporting structure that connects to the platform. This intermediary structure ensures reliable force transmission from the platform to the touch screen while maintaining proper contact geometry, thereby improving measurement reliability without excessive structural complexity.

AI summary
The instant disclosure relates to a scale assembly applicable to a mobile device, which includes a touch screen and a software application (app). The scale assembly includes a platform, one or more sensing member, one or more flexible member, and a base. When an object is placed on the platform, the sensing member of the scale assembly presses the touch screen of the mobile device, and the mobile device, based on the app, reads the change associated with a sensing value detected by the touch screen, and converts the obtained sensing value difference into the weight of the object.
