Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the information processing apparatus uses received signal strength threshold to connect to image processing devices, then connection speed is improved, but connection accuracy deteriorates when multiple devices are present
Solution Approach 1:
The patent adds a spatial dimension to the connection decision by measuring the inclination angle of the information processing apparatus relative to the image processing device. Instead of relying solely on received signal strength (one-dimensional), the system now considers both signal strength and angular orientation (two-dimensional), thereby improving connection accuracy when multiple devices are present while maintaining fast connection speed.
Solution Approach 2:
The patent changes the connection parameter from a single threshold-based signal strength check to a composite evaluation involving both received signal strength and inclination angle. By introducing the inclination angle parameter, the system can distinguish between devices at different spatial orientations, resolving the ambiguity in multi-device environments while preserving the speed advantage of threshold-based connection.
2Ease of operation
If the information processing apparatus automatically connects to any image processing device within range, then ease of operation is improved, but reliability deteriorates due to unintended job transmission
Solution Approach 1:
The patent enhances the automatic connection mechanism by incorporating inclination angle measurement. The system no longer connects to any device within range but specifically connects to devices within a predetermined angular range. This adds spatial orientation awareness to automatic connection, maintaining ease of use while ensuring that jobs are transmitted only to the intended device, thereby improving reliability.
Solution Approach 2:
The inclination angle measurement acts as an intermediary factor between the automatic connection function and the reliability requirement. It mediates the connection decision by filtering out devices that are not within the acceptable angular range, thus enabling automatic connection to work reliably in multi-device environments without requiring user intervention.
