Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If two separate cable holders are rotatably connected to one another to achieve rotatability, then the fastening clip can adapt to different cable orientations, but the manufacturing effort increases and the component becomes more expensive

Engineering Contradiction:
ImproverotatabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges two separate cable holders into a single integrated base body with multiple receptacles. The base body contains multiple receptacles (at least two) that can receive different cable holders, eliminating the need for separate rotatable cable holder components and their complex assembly, while maintaining the ability to accommodate cables at various angles

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base body is designed as a universal component with multiple receptacles that can accommodate different cable holders in various orientations. This multi-functional design allows a single component to perform the function previously requiring multiple separate components, reducing manufacturing complexity while preserving adaptability

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

2Adaptability or versatility

If two separate cable holders are rotatably connected to achieve rotatability, then the fastening clip can adapt to different cable orientations, but the number of assembly steps increases

Engineering Contradiction:
ImproverotatabilityVSAvoidassembly efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple cable holder receptacles into a single base body component, reducing the number of parts that need to be assembled. This integration eliminates multiple assembly steps required for connecting separate rotatable cable holders, thereby improving assembly efficiency and productivity

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If flexible elements are used to connect the holding section to the base body, then the fastening clip can be produced in one piece, but the flexible elements may experience excessive deflection or force without stops

Engineering Contradiction:
Improveone-piece productionVSAvoidflexible element durability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates stop structures within the base body that preliminarily define the movement limits of the flexible elements. These stops are pre-positioned during one-piece production to prevent excessive deflection or force on the flexible elements, ensuring their durability while maintaining the benefits of integrated manufacturing

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The stop structures act as protective measures built into the base body that cushion and limit the movement of flexible elements before excessive force or deflection can occur. This beforehand protection prevents damage to the flexible elements while allowing the one-piece manufacturing approach

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A fastening clip comprises a base body and at least one holding portion which is integrally but flexibly connected to the base body, the base body as well as the holding portion comprising at least one receptacle for an elongated member. The holding portion is reversibly movable with respect to the base body in a predefined range, however, a rotation of the holding portion relative to the base body is limited by first stops.
