Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional splicing apparatus using chains, wire ropes, or belts are employed, then splicing function is achieved, but device complexity and cost increase

Engineering Contradiction:

Improvesplicing functionVSAvoidstructure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential splicing function from complex traditional mechanisms and implements it using a simplified rod apparatus that can be detached and reattached to the slide rail at different positions. This eliminates the need for chains, wire ropes, or belts while maintaining the splicing capability, directly resolving the contradiction between reliability and device complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The splicing apparatus is segmented into modular components: a slide rail with multiple positions and a detachable rod apparatus. This segmentation allows the system to achieve splicing functionality through simple attachment and detachment operations rather than complex continuous mechanisms, reducing overall device complexity while maintaining reliability.

Inventive Principle:

Principle #1Segmentation

2Reliability

If traditional splicing apparatus are used, then splicing operations can be performed, but production efficiency decreases

Engineering Contradiction:

Improvesplicing capabilityVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The rod apparatus can be dynamically repositioned along the slide rail and detached/attached at different positions according to splicing needs. This dynamic adaptability allows quick response to breaking events at various locations without requiring complex reconfiguration, thereby improving production efficiency while maintaining splicing capability.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The slide rail is pre-configured with multiple positions and the rod apparatus is designed for quick attachment and detachment. When a break occurs, the rod can be rapidly repositioned to the appropriate location and attached, minimizing downtime and maintaining high production efficiency without compromising splicing reliability.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If conventional splicing mechanisms are implemented, then strip material can be spliced, but cost increases

Engineering Contradiction:

Improvesplicing functionVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The rod apparatus is designed as a simple, inexpensive component that can be easily manufactured and replaced if needed. This simple structure, consisting essentially of a rod and attachment mechanism, dramatically reduces manufacturing cost compared to traditional chains, wire ropes, or belts while maintaining the essential splicing function.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent replaces complex mechanical splicing systems (chains, wire ropes, belts) with a simplified rod-based mechanism that uses basic mechanical attachment and detachment. This substitution maintains splicing functionality while significantly reducing manufacturing complexity and cost.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
