Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed signal threshold is used for protocol switching, then the switching decision is simple, but it leads to inaccurate switching points and unnecessary energy consumption due to variations in cordless base unit ranges
Solution Approach 1:
The patent dynamically adjusts the signal strength threshold parameter based on the detected cordless base unit range. Instead of using a fixed threshold, the system modifies the threshold value to match the specific characteristics of each base unit model, thereby achieving accurate switching points that prevent unnecessary protocol transitions and reduce energy consumption.
Solution Approach 2:
The system implements a feedback mechanism where the detected cordless base unit range is used to adjust the signal threshold for protocol switching. The handset continuously monitors the cordless signal strength and compares it against the dynamically determined threshold, creating a closed-loop control system that optimizes switching decisions based on actual signal conditions.
2Device complexity
If protocol switching threshold is not accurately determined, then device complexity is reduced, but communication reliability deteriorates due to premature or delayed switching
Solution Approach 1:
The patent performs preliminary testing and detection of the cordless base unit range during the initialization phase or before actual communication begins. This preliminary action determines the appropriate signal threshold in advance, ensuring that the threshold is accurately set before protocol switching decisions are made, thereby maintaining communication reliability without adding complexity during active communication.
3Reliability
If seamless protocol switching is implemented, then communication reliability is improved, but device complexity increases due to multiple communication protocols and switching logic
Solution Approach 1:
The patent simplifies the multi-protocol switching logic by dynamically adjusting a single key parameter - the signal strength threshold - based on the detected cordless base unit range. This approach avoids the need for complex decision matrices while maintaining seamless switching, as the adaptive threshold automatically accounts for variations in base unit capabilities and signal characteristics.

AI summary
A system and method for establishing a signal parameter threshold for switching between communications protocols by a multimode handset may include providing cordless telephones of different models. A dropout point at which a communications signal of each of the cordless telephones deteriorates below a predetermined level may be determined. At least one signal parameter of the communications signal at the determined dropout point of each of the cordless telephones may be measured and collected. The signal parameter(s) associated with the cordless telephone having the shortest range at which the associated dropout point may be determined so that a multimode handset may be established with the signal parameter(s) to cause the multimode handset to switch communications protocols in response to the multimode handset crossing a signal parameter threshold level defined by the predetermined signal parameter(s) when communicating with a base unit of a cordless telephone.
