Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional multi-component sunshade hooks are used, then structural integrity is maintained, but assembly time increases and risk of part failure increases

Engineering Contradiction:

Improverisk of part failureVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent combines multiple separate components (brackets, hooks, covers) into a single integrated glass run channel component with molded-in sunshade hooks. This merging eliminates the need for separate assembly steps and reduces the number of parts that can fail, directly addressing both the reliability and assembly time concerns.

Inventive Principle:

Principle #5Merging (Combining)

2Device complexity

If multiple separate components are used for sunshade hooks, then ease of repair is maintained, but device complexity increases

Engineering Contradiction:

Improvenumber of componentsVSAvoidease of repair

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The sunshade hooks are molded directly into the glass run channel as an integrated component, reducing the total number of parts from seven to one. This simplification reduces device complexity while maintaining repairability through the overall component replacement approach.

Inventive Principle:

Principle #5Merging (Combining)

3Manufacturing precision

If traditional assembly method with multiple parts is used, then adaptability is maintained, but manufacturing precision requirements increase

Engineering Contradiction:

Improvealignment precisionVSAvoidadaptability

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

By molding the hooks directly into the glass run channel, the patent eliminates the need for precise alignment and fastening of separate components. The integrated design reduces manufacturing precision requirements for assembly while maintaining the adaptability of the sunshade system through the functional integrity of the molded component.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A glass run channel includes a header and one or more inserts molded into the header. The header includes an upper header wall, an outer header wall extending from the upper header wall, and an inner header wall extending from the upper header wall opposite the outer header wall. The inserts include an upper insert wall provided within the upper header wall, an insert body extending from the upper insert wall and provided within the inner header wall, and a hook wall extending from the insert body. The header fully surrounds the inserts. A portion of the header surrounding the one or more inserts defines a hook for a sunshade.
