Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If lead wires are fixed and attached to an adapter, connector or clamp, then the lead wires are secured, but individual lead wires cannot be movable to reach different locations

Engineering Contradiction:

Improvelead wire securityVSAvoidlead wire position flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The lead wire slide incorporates a sliding mechanism that allows lead wires to move dynamically along the slide body. The wire guide channels enable wires to be repositioned to different locations while remaining secured during each position, thus providing both reliability and adaptability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The lead wire slide is divided into multiple wire guide channels, each capable of independently accommodating and positioning individual lead wires. This segmentation allows each wire to be moved and secured at different positions along its respective channel.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If lead wires are placed in grooves of two connectable pieces, then the wires are organized, but the system becomes more complex and requires assembly of multiple parts

Engineering Contradiction:

Improvewire organizationVSAvoidnumber of parts

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invention merges the wire guide channels and the connecting structure into a single integrated lead wire slide body. This eliminates the need for separate grooved pieces while maintaining wire organization and adding modular connectivity capabilities.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lead wire slide serves multiple functions: it organizes and guides multiple lead wires simultaneously, provides a connecting interface for modular assembly, and enables both secure positioning and reconfigurability. This multi-functionality reduces the need for separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Quantity of substance

If many lead wires are used in EEG, then comprehensive brain coverage is achieved, but the wires become tangled and difficult to manage

Engineering Contradiction:

Improvenumber of electrodesVSAvoidwire management

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The lead wire slide divides the management of multiple lead wires into separate, parallel wire guide channels. Each channel independently guides one or more wires, preventing tangling even when many wires are used simultaneously for comprehensive EEG coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wire guide channels extend in a direction transverse to the longitudinal axis of the slide, creating a two-dimensional arrangement of wires. This spatial organization in multiple dimensions prevents wires from becoming tangled while accommodating a large number of electrodes.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

4Ease of operation

If lead wires are pulled to attach electrodes, then electrode attachment is achieved, but other lead wires may be unintentionally moved or detached

Engineering Contradiction:

Improveelectrode attachmentVSAvoidunintentional detachment

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Each lead wire is accommodated in its own wire guide channel, creating independent pathways. When one wire is pulled for electrode attachment, the frictional engagement within its specific channel prevents adjacent wires from being unintentionally moved or detached.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wire guide channels act as intermediary structures between the lead wires and the external environment. These channels provide controlled frictional engagement that allows intentional wire movement while preventing unintended movement of other wires.

Inventive Principle:

Principle #24Intermediary (Mediator)
