Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users carry lithium batteries separately without integrated storage, then the batteries can be accessed quickly, but the USB cables become entangled with other objects and the batteries collide and rub against items causing damage

Engineering Contradiction:

ImproveConvenience of carrying and accessing batteryVSAvoidBattery functionality and protection from damage

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines the battery storage bag with the battery itself, creating an integrated assembly where the bag contains the battery along with its charging cable and accessories. This merging eliminates the need for separate storage and prevents cable entanglement and battery damage during transport.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a nested structure where the battery is placed inside the storage bag, and the charging cable is stored within the same bag. This nested arrangement protects all components from external damage and prevents tangling while maintaining easy accessibility.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the charging cable is left loose and unsecured, then it is easily accessible for charging, but it becomes entangled with other objects and causes the battery to collide and rub against items

Engineering Contradiction:

ImproveAccessibility of charging cableVSAvoidEntanglement and mechanical damage from rubbing

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent provides a designated sleeve or compartment within the storage bag where the charging cable can be preliminarily arranged and secured before use. This preliminary organization prevents entanglement during transport while allowing quick access when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses a flexible storage bag with a sleeve or compartment that can accommodate the charging cable in a neat, protected manner. The flexible material allows the cable to be stored securely without rigid constraints, preventing damage while maintaining accessibility.

Inventive Principle:

Principle #30Flexible shells and thin films

3Ease of manufacture

If the battery is stored in a separate bag without integration, then storage is simple, but users must temporarily find a storage bag and the battery lacks protection during transport

Engineering Contradiction:

ImproveSimplicity of storage solutionVSAvoidBattery protection from wear and tear

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent merges the storage bag and battery into a single integrated unit, eliminating the need for separate storage solutions. This integration ensures the battery is always protected during transport while maintaining simplicity in the storage approach.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated battery assembly serves multiple functions: it provides storage for the battery, charging cable, and accessories; it protects the battery from damage; and it offers a portable charging solution. This multi-functionality eliminates the need for multiple separate items.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Reliability

If the charging interface is not exposed on the bag body, then the battery is fully protected inside, but the charging interface cannot be accessed for charging

Engineering Contradiction:

ImproveBattery protection inside storage bagVSAvoidAccessibility of charging interface

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent positions the charging interface of the battery on the side of the bag body that faces outward, allowing the interface to be exposed and accessible without requiring the bag to be opened. This preliminary positioning enables charging while the battery remains protected inside the bag.

Inventive Principle:

Principle #10Preliminary action
