Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual pressing of individual wires into IDCs is used, then reliable electrical contact is achieved, but the wiring process becomes cumbersome and time-consuming

Engineering Contradiction:
Improveelectrical contact reliabilityVSAvoidwiring speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines multiple wire termination functions into a single integrated wiring block structure. The wiring block simultaneously accommodates multiple wires and provides contact pressure through its design, eliminating the need for individual manual pressing operations while maintaining reliable electrical contact across all wire positions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The wiring block is designed to automatically provide contact pressure and secure wire positioning through its inherent structural features. The deformable receiving elements and overall block design enable the system to self-terminate multiple wires without requiring external manual pressing tools or operations for each individual wire.

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If individual manual wire pressing is required, then precise wire positioning is achieved, but the device complexity increases

Engineering Contradiction:
Improvewire positioning precisionVSAvoidconnector structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The wiring block serves multiple functions simultaneously: it accommodates multiple wires, provides positioning structures for precise wire placement, and delivers contact pressure through its design. This multi-functional integration reduces the need for separate components and manual operations, simplifying the overall device while maintaining precision.

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

Solution Approach 2:

The wiring block incorporates multiple deformable receiving elements that are distributed across its structure, with each element responsible for a specific wire position. This segmentation allows independent wire termination at each position while the overall block provides structural support and contact pressure, achieving precise positioning without complex individual mechanisms.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If deformable receiving elements are used to simplify wiring, then ease of operation improves, but manufacturing precision may be compromised

Engineering Contradiction:
Improvewiring easeVSAvoidconnection precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The receiving elements are designed to be deformable, allowing them to adapt to wire insertion and provide contact pressure dynamically. This dynamic characteristic simplifies the wiring operation by eliminating the need for precise manual pressing, while the controlled deformability ensures consistent contact force and positioning precision is maintained through the element's elastic recovery.

Inventive Principle:
Principle #15Dynamics
