Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws or bolts are used to fasten the battery to the main body, then the battery is securely fixed during flight, but the battery replacement process becomes time-consuming and inconvenient

Engineering Contradiction:
Improvebattery fixation stabilityVSAvoidbattery replacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The fastening mechanism is divided into multiple clamp buttons distributed along the battery package, each independently fastening different sections of the battery to the main body. This segmentation allows for quicker release and attachment compared to a single complex fastening system, reducing replacement time while maintaining secure fixation during flight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The clamp buttons are designed to be manually pressable to release the fastening state, transforming the static screw-fastening system into a dynamic one that can quickly transition between locked and unlocked states. This dynamic mechanism enables rapid battery replacement without requiring tools or complex operations.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a sealing board with screws is used to prevent battery dropping, then the battery is securely held during flight, but the operation complexity increases due to the need to loosen and tighten fasteners

Engineering Contradiction:
Improvebattery retention during flightVSAvoidbattery replacement convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The clamp buttons are designed to be self-operating through manual pressing, eliminating the need for external tools or complex fastening procedures. The user can directly press the clamp buttons to release or secure the battery, making the operation simple and intuitive while ensuring reliable retention during flight.

Inventive Principle:
Principle #25Self-service

3Device complexity

If a simple open cavity is used for battery accommodation, then the structure is simple, but the battery can drop during flight

Engineering Contradiction:
Improvebattery cavity structureVSAvoidbattery security during flight
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The battery package incorporates multiple clamp buttons distributed along its length, dividing the fastening function into several points of contact. This segmented approach provides secure retention during flight while adding minimal structural complexity compared to a fully enclosed or heavily braced cavity design.

Inventive Principle:
Principle #1Segmentation
