Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If power is distributed to multiple terminals simultaneously, then all terminals can be charged, but the terminal most urgently requiring charging cannot be rapidly charged
Solution Approach 1:
The patent implements dynamic power distribution by allowing the power supply apparatus to adjust power allocation in real-time based on charging states and user-defined priorities. The controller dynamically switches between different power distribution modes: simultaneous charging when no priority is needed, and priority-based sequential charging when rapid charging of specific terminals is required. This dynamic adaptability resolves the contradiction by making the system flexible enough to handle both multi-terminal charging and rapid priority charging scenarios.
Solution Approach 2:
The patent applies local quality by enabling different charging characteristics for different terminals based on their individual needs and user-defined priorities. Each terminal can receive customized power allocation, charging timing, and power levels. The controller identifies specific terminals requiring rapid charging and concentrates power resources on those terminals while adjusting or delaying power delivery to other terminals, thus providing localized optimized charging quality to each terminal.
2Loss of energy
If preset power is distributively transmitted to multiple terminals, then power is shared among terminals, but charging cannot be performed according to user-intended order
Solution Approach 1:
The patent implements feedback mechanisms where the power supply apparatus continuously monitors charging states of all terminals and compares them against user-defined priority settings. The controller receives feedback information about battery levels, charging speeds, and terminal positions, then adjusts power distribution accordingly. This feedback loop enables the system to maintain efficient power distribution while simultaneously respecting user-intended charging orders, as the controller can see the current state and make informed decisions about power allocation.
Solution Approach 2:
The patent makes the power supply apparatus universal by enabling it to perform multiple charging distribution functions: it can operate in simultaneous charging mode for efficient power distribution, switch to priority-based sequential charging for user-controlled ordering, and adapt to different terminal configurations. The controller integrates multiple functions including power management, priority arbitration, position detection, and real-time adjustment, allowing the single apparatus to handle diverse charging scenarios efficiently.
3Reliability
If wireless power transmission is used, then waterproof function is improved and portability is increased, but individual control and position detection of multiple terminals becomes difficult
Solution Approach 1:
The patent introduces communication modules and position detection modules as intermediaries between the power supply apparatus and multiple terminals. These intermediaries facilitate wireless identification, positioning, and control signaling without requiring physical contact. The communication modules enable the apparatus to detect terminal positions and transmit control signals wirelessly, while position detection modules provide spatial information for accurate power targeting. This intermediary layer manages the complexity of controlling multiple wireless terminals while preserving the waterproof and portable benefits of wireless power transmission.
