Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional charging cables are used to charge electronic devices, then charging functionality is provided, but device complexity and ease of operation deteriorate due to cable management requirements

Engineering Contradiction:

Improvecharging functionalityVSAvoidcable management

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent combines the charging cable connection function with the seat structure by integrating a power supply base into the seat. The power supply base includes electrical connection terminals that directly connect to the electronic device when placed on the seat, eliminating the need for separate cable management and providing a more convenient charging solution.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The power supply base acts as an intermediary between the vehicle's power system and the electronic device. It provides a fixed charging interface built into the seat, serving as a mediator that eliminates the need for users to manually manage charging cables while still providing power transfer functionality.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If electronic devices are fastened to seats via holders, then device stability is improved, but ease of operation deteriorates because devices cannot be moved, removed, or replaced

Engineering Contradiction:

Improvedevice stabilityVSAvoiddevice mobility

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent employs a magnetic support portion that provides dynamic holding capability. The magnetic force maintains the electronic device in a stable position when needed, but allows easy removal when the user wants to move or replace the device, thus providing both stability and mobility without requiring mechanical fasteners.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If holders are placed on seats with electronic devices, then device support is provided, but safety deteriorates due to potential safety problems for rear-row passengers

Engineering Contradiction:

Improvedevice supportVSAvoidpassenger safety

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the device support function from traditional mechanical holders and implements it through magnetic attraction integrated into the seat structure. This eliminates protruding mechanical components that could pose safety hazards to passengers, while still providing effective device support through the magnetic support portion.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of manufacture

If electrical connection terminals are arranged for single-direction plugging, then manufacturing simplicity is maintained, but adaptability deteriorates because bidirectional plugging is not supported

Engineering Contradiction:

Improveterminal arrangementVSAvoidplugging flexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent uses symmetrical arrangement of electrical connection terminals to enable bidirectional plugging capability. By arranging the terminals symmetrically, the power supply base can accept electronic devices plugged in from either direction, providing plugging flexibility while maintaining manufacturing simplicity through the regular pattern.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The electrical connection terminals are designed with universal functionality to support both forward and reverse plugging modes. The same terminal arrangement serves multiple plugging directions, eliminating the need for separate terminal configurations for different plugging orientations and enhancing adaptability without increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
