Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing electronic scale structure is used, then weighing function is achieved, but volume and weight increase making it inconvenient to carry
Solution Approach 1:
The scale is divided into separate modules: a housing unit, a detachable upper cover, and a separate battery compartment. This segmentation allows the scale to be assembled and disassembled, reducing the effective weight when carrying only the necessary components while maintaining full weighing functionality when assembled.
Solution Approach 2:
The upper cover is designed to be detachable rather than fixed, allowing dynamic reconfiguration of the scale. Users can attach the upper cover when weighing is needed and remove it for portability, transforming the scale from a static heavy unit to a flexible portable system.
2Ease of operation
If existing electronic scale structure is used, then weighing function is achieved, but volume increases making it inconvenient to carry
Solution Approach 1:
The scale structure is segmented into a main housing and a separate upper cover assembly. When disassembled, the upper cover can be removed or stored separately, significantly reducing the volume of the scale during transport while maintaining complete functionality when assembled.
Solution Approach 2:
The upper cover is designed to nest within or attach to the housing when not in use, creating a compact configuration that minimizes volume. The bracket structure allows the upper cover to be stored in a folded or nested position, reducing overall scale volume for portability.
3Measurement precision
If weighing sensor is fixed firmly to ensure accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The first and second brackets are pre-installed and fixed to the housing before the weighing sensor is positioned. This preliminary action ensures proper alignment and secure mounting of the sensor, guaranteeing measurement precision while simplifying the overall assembly process rather than increasing complexity.
Solution Approach 2:
The bracket structure is integrated into the housing design, merging the mounting function with the structural housing. This integration eliminates separate complex mounting mechanisms while ensuring the weighing sensor is firmly and accurately positioned through the combined bracket-housing assembly.
