Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If power cords are used to connect the power adapter to the photography light, then power can be supplied to the light, but the cords drag and tangle during use, causing inconvenience for storage

Engineering Contradiction:
Improveconvenience of power connectionVSAvoidcord management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The power connection system is segmented into two parts: a fixed power adapter with connecting component and a detachable power supply module (battery or AC adapter) with corresponding connector. This segmentation eliminates the need for long power cords, as the power supply module attaches directly to the light body, thereby solving the cord tangling and storage inconvenience problems while maintaining easy power connection capability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting component (comprising connecting block and connecting groove) acts as an intermediary mechanism between the power adapter and the power supply module. This intermediary enables direct coupling without requiring external power cords, thus eliminating the cord management issues while facilitating straightforward power connection and detachment operations

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the power adapter is detachably connected to the light body, then cord tangling is eliminated and storage is simplified, but the connection structure becomes more complex

Engineering Contradiction:
Improvepower connection structureVSAvoidease of power module attachment
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The traditional mechanical cord-based connection system is replaced with a direct mechanical coupling system using connecting blocks and grooves. This substitution eliminates the need for flexible cords while providing a secure, tool-free attachment mechanism that is simple to operate - users only need to align and push the power supply module onto the light body, achieving both structural integration and operational simplicity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The connecting block is designed to fit precisely into the connecting groove, creating a nested configuration where the power supply module attaches to the light body in a space-efficient manner. This nesting approach minimizes the overall profile when attached and simplifies the connection structure by eliminating external cords and connectors

Inventive Principle:
Principle #7Nested doll (Nesting)
