Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a single storage battery is used in the handheld fan, then the device complexity is low, but the battery capacity is insufficient and battery life is short

Engineering Contradiction:
Improvebattery lifeVSAvoidbattery module complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

The battery module is segmented into a battery housing and multiple storage batteries (first storage battery and second storage battery). This segmentation allows the batteries to be arranged separately within the housing, enabling extended battery life through series or parallel connections while maintaining manageable device complexity through modular organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage batteries are nested within the battery housing, which itself is integrated into the handheld portion of the fan. This nesting structure allows the battery system to be compactly organized, providing extended battery life without significantly increasing the overall device complexity or size.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If multiple storage batteries are connected in series or parallel, then the battery capacity increases, but the electrical connection complexity increases

Engineering Contradiction:
Improvebattery capacityVSAvoidelectrical connection complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The first storage battery and second storage battery are merged into a single battery module with integrated electrical connections. The batteries are connected in series or parallel within the battery housing, combining their capacity while managing electrical connection complexity through unified module design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery module is designed to provide multiple functions: it can operate with batteries connected in series for higher voltage or in parallel for higher capacity, making it a universal power solution that adapts to different power requirements while maintaining a single structural design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Duration of action of moving object

If the battery module is integrated into the handheld portion, then the portability is maintained, but the space for battery arrangement is limited

Engineering Contradiction:
Improvebattery lifeVSAvoidbattery housing volume
Core Design Contradiction:
Duration of action of moving objectVSVolume of stationary object

Solution Approach 1:

The storage batteries are nested within the battery housing, which is itself integrated into the handheld portion of the fan. This nested structure maximizes the use of available space within the compact handheld form factor, allowing extended battery life without significantly increasing the external dimensions of the device.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The batteries are arranged in different spatial configurations (series or parallel connections) within the battery housing, utilizing three-dimensional space efficiently. This dimensional arrangement allows adequate battery capacity for extended life while maintaining a compact handheld size.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A handheld fan includes an air supply portion and a handheld portion. The handheld portion includes a first outer shell and a battery module arranged in the first outer shell. The battery module includes a battery housing, and a first storage battery and a second storage battery which are arranged in the battery housing. The first storage battery and the second storage battery are connected in series through an electrical connector. The first storage battery and the second storage battery are arranged in a battery housing. The first storage battery and the second storage battery are connected in series or in parallel through an electric connector, which increases the battery capacity of the handheld fan, so that when a user uses the handheld fan, the battery life can be longer, bringing a better user experience.
