Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the information processing apparatus measures received signal strength to connect to an image processing device, then connection is established, but the apparatus may accidentally connect to the wrong device when multiple devices are present
Solution Approach 1:
The patent introduces inclination measurement as a new dimension beyond signal strength measurement. The measuring unit measures both the strength of received radio waves and the inclination of the information processing apparatus relative to the image processing device. By adding this spatial orientation dimension, the system can distinguish between devices that have similar signal strengths but different spatial relationships, thereby resolving the contradiction between connection reliability and measurement precision.
Solution Approach 2:
The patent changes the parameters used for device selection from solely signal strength to a combination of signal strength and inclination angle. The selection unit evaluates multiple parameters including the strength of received signals and the measured inclination to determine the most appropriate image processing device to connect to. This multi-parameter approach improves connection accuracy by providing more discriminatory information when multiple devices are present.
2Productivity
If the apparatus connects based on highest signal strength, then connection is established quickly, but jobs may be sent to unintended devices
Solution Approach 1:
The patent adds inclination measurement as an additional dimension to the device selection process. Instead of relying solely on signal strength for quick connection, the system now considers both signal strength and the physical orientation of the apparatus relative to the target device. This allows faster connection establishment while maintaining reliability by using the inclination parameter to verify correct device identification.
Solution Approach 2:
The inclination measurement acts as an intermediary parameter that mediates between the speed of connection establishment and the accuracy of device selection. By introducing this intermediate measurement, the system can quickly assess both signal strength and orientation, then use the combination of these factors to make accurate device selection decisions without significantly delaying the connection process.
3Adaptability or versatility
If multiple image processing devices are disposed in proximity, then device availability increases, but signal interference and wrong connection risk increase
Solution Approach 1:
The patent introduces spatial orientation (inclination) as an additional dimension to differentiate between multiple image processing devices disposed in proximity. When several devices are available, the measuring unit measures the inclination relative to each device, and the selection unit uses this spatial information alongside signal strength to identify the intended target device, thereby maintaining connection reliability even with high device availability.
Solution Approach 2:
The patent applies local quality by considering the specific spatial relationship (inclination) between the information processing apparatus and each individual image processing device. Rather than treating all devices uniformly, the system evaluates the local geometric configuration and signal characteristics specific to each device-apparatus pair, enabling accurate selection among multiple nearby devices.
