Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users can select options in an online lottery system, then user participation and selection freedom are improved, but inventory management complexity and selection efficiency deteriorate due to many participants and inability to monopolize options
Solution Approach 1:
The system performs preliminary actions by displaying inventory status images before users make selections. This allows users to see available options and their quantities in advance, enabling informed decisions without requiring complex real-time management during the selection process. The inventory status is prepared and presented beforehand, reducing the complexity of managing concurrent selections from multiple users.
2Productivity
If inventory status information is provided to users, then selection efficiency is improved, but information processing requirements and system complexity increase
Solution Approach 1:
The system creates simplified copies of inventory status information in the form of visual images that are easy to understand. Instead of providing detailed numerical data or complex inventory records, the system generates visual representations (images showing inventory status) that convey essential information at a glance. This copying approach maintains selection efficiency while avoiding the complexity of processing and displaying detailed inventory data.
3Reliability
If the system prevents users from selecting already chosen options, then inventory accuracy is improved, but selection process time and user experience deteriorate
Solution Approach 1:
The system displays inventory status images showing available options and their quantities before users make selections. This preliminary display of accurate inventory information allows users to make informed choices without needing to wait for real-time updates during the selection process. Users can see what is available and select accordingly, maintaining inventory accuracy while avoiding time delays associated with real-time validation and error handling.
