Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If multiple batteries are equipped to increase capacity, then the power supply capacity is improved, but the device becomes heavier and more cumbersome

Engineering Contradiction:
Improvebattery capacityVSAvoiddevice weight
Core Design Contradiction:
Quantity of substanceVSWeight of moving object

Solution Approach 1:

The battery system is divided into a first battery that remains in the power supply device and second batteries that can be separately added or removed. This segmentation allows the device to maintain a lightweight base configuration while enabling users to add capacity only when needed, resolving the contradiction between portability and power supply capacity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery configuration transitions from a static fixed-capacity design to a dynamic adjustable configuration. The telescopic component allows the device to adapt its battery capacity based on usage requirements, enabling the device to be lightweight during transport and high-capacity during use, thus resolving the weight-capacity contradiction.

Inventive Principle:
Principle #15Dynamics

2Quantity of substance

If multiple batteries are equipped to increase capacity, then the power supply capacity is improved, but the ease of operation deteriorates due to cumbersome handling

Engineering Contradiction:
Improvebattery capacityVSAvoidportability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

By separating the battery system into a permanent first battery and removable second batteries, the device maintains ease of operation in its base state while providing an simple addition mechanism for increased capacity. The telescopic component provides a straightforward interface for adding or removing batteries, preserving operational simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second batteries are nested on the telescopic component, which can be extended from or retracted into the power supply device. This nesting arrangement provides an intuitive and simple mechanism for adding or removing capacity, maintaining ease of operation while enabling flexible capacity adjustment.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If a telescopic component is added to enable flexible battery installation, then the ease of operation is improved, but the device complexity increases

Engineering Contradiction:
Improvebattery installation convenienceVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The telescopic component serves multiple functions: it provides a mounting structure for second batteries, acts as a protective cover when retracted, and serves as the interface for adding or removing batteries. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while improving ease of operation.

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

Solution Approach 2:

The telescopic component combines the functions of a battery mount, protective cover, and interface mechanism into a single integrated structure. By merging these functions, the design avoids adding multiple separate components, thus limiting the increase in structural complexity while achieving improved battery installation convenience.

Inventive Principle:
Principle #5Merging (Combining)
