Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate mechanical and electrical interfaces are used for battery connection, then reliable mechanical and electrical coupling is achieved, but the connection process becomes complex and time-consuming

Engineering Contradiction:
Improvemechanical and electrical coupling reliabilityVSAvoidconnection process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines separate mechanical and electrical interfaces into a single integrated coupling interface. The coupling interface includes both mechanical coupling elements (such as a coupling flange with mounting holes) and electrical coupling elements (such as electrical contacts or plug connectors) that work together as one unified component, allowing simultaneous mechanical and electrical connection in a single operation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling interface is designed to perform multiple functions simultaneously: it provides mechanical attachment, electrical connection, and alignment guidance all through one interface structure. This multi-functional design eliminates the need for separate mechanical and electrical coupling operations, reducing overall system complexity while maintaining reliable connections for both mechanical and electrical functions.

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

2Reliability

If separate mechanical and electrical coupling processes are used, then secure battery fixation is achieved, but the battery exchange time increases

Engineering Contradiction:
Improvebattery fixation securityVSAvoidbattery exchange time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges mechanical and electrical coupling operations into a single simultaneous action. When the battery is mounted or removed, both the mechanical coupling elements and electrical coupling elements engage or disengage together, allowing battery exchange to be completed in one operation rather than requiring sequential mechanical then electrical connection steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The coupling interface is pre-configured with alignment features and pre-positioned coupling elements that guide the connection process. The mechanical and electrical components are arranged in advance to automatically align and engage simultaneously, eliminating the need for separate alignment and connection steps during battery exchange.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a dual-function coupling interface is used, then battery exchange speed is improved, but the interface design becomes more complex

Engineering Contradiction:
Improvebattery exchange speedVSAvoidcoupling interface design complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The coupling interface is designed as a universal multi-functional component that handles mechanical attachment, electrical connection, and alignment guidance through a single integrated structure. This approach, while requiring careful initial design, actually reduces overall system complexity by eliminating the need for multiple separate interfaces and their associated mounting hardware, fasteners, and alignment features.

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

4Use of energy by moving object

If electrically conductive coupling elements are used, then electrical energy transfer is enabled, but the risk of short circuits increases

Engineering Contradiction:
Improveelectrical energy transfer efficiencyVSAvoidshort circuit risk
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The coupling interface applies local quality differentiation by providing electrical conductivity only at specific localized contact points rather than across the entire interface surface. The electrical contacts are positioned precisely at designated locations where connection is intended, while surrounding areas maintain electrical insulation through non-conductive materials or geometric separation, thereby enabling efficient energy transfer at contact points while minimizing short circuit risk elsewhere.

Inventive Principle:
Principle #3Local quality
