Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If solar and wind power generating equipment is used, then green energy can be generated, but the equipment is huge, costly, and has geographical limits
Solution Approach 1:
The patent divides the energy storage system into modular energy storage units that can be independently connected in parallel. Each unit is a self-contained module with standardized terminals, allowing the system to be built incrementally without requiring large-scale infrastructure installation.
Solution Approach 2:
The patent employs a hierarchical structure where multiple energy storage units are nested within an energy storage module, which in turn is integrated into a portable green power device. This nested arrangement allows compact packaging while maintaining expandability.
2Quantity of substance
If multiple energy storage units are connected in parallel to expand capacity, then power storage capacity increases, but voltage differences between units may cause charging/discharging issues
Solution Approach 1:
The patent implements a dynamic self-balancing mechanism that continuously monitors and adjusts the voltage levels of parallel-connected energy storage units. The control unit dynamically identifies the unit with the lowest voltage and directs charging current to it, maintaining voltage equilibrium across all units during operation.
Solution Approach 2:
The control unit continuously monitors the voltage levels of all energy storage units and uses this feedback information to intelligently control the charging and discharging processes. The system automatically adjusts current distribution based on real-time voltage status, ensuring optimal performance and preventing overcharging or undercharging.
3Ease of operation
If kinetic energy is generated through handle operation, then portable power can be produced, but the power generation capacity is limited by manual effort
Solution Approach 1:
The patent combines multiple energy generation approaches (kinetic energy from handle operation, solar power, and wind power) into a single integrated system. The kinetic power generating module, solar power generating module, and wind power generating module work together to supplement each other, allowing the system to achieve higher power output than any single source could provide alone.

AI summary
A portable green power device includes a case, an energy storage module, a kinetic power generating module, a control unit, and a port for discharging. The energy storage module has an input terminal set, an output terminal set, a protection circuit, and a parallel dynamic self-balancing mechanism. The output terminal set may be connected to an additional energy storage unit to expand power storage capacity of the portable green power device. The parallel dynamic self-balancing mechanism enables synchronous charging and discharging under a voltage level which is dynamically reached and falls between voltages of all the energy storage units connected in parallel. The control unit tracks and collects energy generated by the kinetic power generating module at a maximum power point and allows transfer of the generated energy to the energy storage module.
