Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If connectors are provided on the way in the extending direction to enable electrical connections at arbitrary positions, then the flexibility of connection position is improved, but the device complexity and component count increase

Engineering Contradiction:

Improveflexibility of connection positionVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the connection portion with the plate wiring member itself, forming an integrated structure where the connection portion is a protruding part of the lower plate wiring member that passes through the upper plate wiring member. This eliminates the need for separate connectors and reduces component count while enabling electrical connections at arbitrary positions along the extending direction.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent utilizes the vertical stacking dimension to achieve horizontal connectivity. By having the connection portion of the lower plate wiring member pass through the upper plate wiring member in the vertical direction, the invention enables electrical connections at arbitrary positions along the extending direction without adding components in the horizontal plane, thus solving the contradiction between connection flexibility and device complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

Engineering Contradiction:

Improveflexibility of connection positionVSAvoidnumber of components

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The connection portion is merged with the plate wiring member to form an integrated structure. The connection portion is formed as a protruding part of the lower plate wiring member that extends through the upper plate wiring member, eliminating the need for separate connector components and reducing the overall component count while maintaining the ability to make electrical connections at arbitrary positions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The plate wiring member serves multiple functions: it provides the main conductive path and simultaneously incorporates the connection portion that enables electrical connections at arbitrary positions. This multi-functionality reduces the number of components by making the plate wiring member itself capable of both power transmission and connection functions.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If the plate wiring member is connected only at both ends, then the structure is simple and the number of components is reduced, but the flexibility of connection position is limited

Engineering Contradiction:

Improvestructure simplicityVSAvoidflexibility of connection position

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The plate wiring member is segmented into functional regions: the main body portion that provides the conductive path and the connection portion that protrudes to enable connections. This segmentation allows the plate wiring member to maintain structural simplicity while providing multiple connection points along its length, thus improving connection flexibility without significantly increasing overall complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention adds connectivity in the vertical dimension by having the connection portion of the lower plate wiring member pass through the upper plate wiring member. This vertical passage enables horizontal connectivity at arbitrary positions while maintaining the simple laminated structure, thus resolving the contradiction between structural simplicity and connection flexibility.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
