Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If mobile power pack capacitance is increased, then charging capacity is improved, but weight increases resulting in poor portability
Solution Approach 1:
The mobile power pack system is divided into multiple independent modules (first mobile power pack and second mobile power pack), each with its own charging unit and battery. These modules can be used separately or stacked together, allowing users to segment the total capacitance into manageable portions that balance charging capacity needs with portability requirements.
Solution Approach 2:
The second mobile power pack is designed to stack on top of the first mobile power pack, creating a nested configuration. The probe-type connectors enable the stacked modules to electrically connect and function as a unified power source, effectively nesting smaller capacity units to achieve larger total capacity when needed while maintaining individual portability.
2Weight of moving object
If mobile power pack capacitance is decreased, then weight is reduced improving portability, but charging capacity becomes insufficient for practical use
Solution Approach 1:
Instead of providing a single large-capacity power pack that compromises portability, the system segments capacitance into multiple smaller modules. Each module maintains sufficient charging capacity for basic needs while remaining lightweight, and users can combine segments to achieve higher total capacity when the application requires it.
Solution Approach 2:
The system provides dynamic configurability where the effective capacitance can be adjusted by stacking one or more second mobile power packs on the first mobile power pack. This allows the charging capacity to dynamically adapt to different usage scenarios, providing just enough capacity for each situation without always carrying excessive weight.
3Quantity of substance
If multiple mobile power packs are stacked to increase charging capacity, then capacitance is improved, but device complexity increases
Solution Approach 1:
Each mobile power pack module is designed with universal functionality, containing its own complete charging unit, battery, and probe-type connectors. This multi-functional design allows each module to operate independently or be combined with others, simplifying the overall system architecture by making each component self-sufficient rather than requiring complex inter-module dependencies.
Solution Approach 2:
When multiple mobile power packs are stacked, they merge into a unified power source through the probe-type connector interface. The magnetic attraction automatically aligns and connects the modules, merging their capacitance and charging functions without requiring complex mechanical or electrical assembly procedures, thus reducing operational complexity despite increased total capacity.

AI summary
A mobile power pack combination of the present invention includes a first mobile power pack and at least a second mobile power pack. The first mobile power pack has a first housing. The first housing is disposed with a first charging unit and a first probe-type connector connected to the first charging unit. The second mobile power pack has a second housing. The second housing is disposed with a second charging unit, a first probe-type connector and a second probe-type connector connected to the second charging unit. When the second mobile power pack is stacked on the first mobile power pack, the second probe-type connector of the second mobile power pack is connected with the first probe-type connector of the first mobile power pack to make electric current conduct. Therefore, the mobile power pack combination provides charging function based on stackable technology and is convenient to carry.
