Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional components (parking piston, parking caliper) are added to monoblock type caliper for actuator integration, then braking function is achieved, but manufacturing cost increases and productivity decreases

Engineering Contradiction:
Improvebraking functionVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines the parking caliper and sliding caliper functions into a single integrated caliper body structure. The caliper body includes both the parking brake application portion and the sliding brake application portion, eliminating the need for separate parking piston and parking caliper components. This merging approach achieves the braking function while reducing part count and manufacturing complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If additional components are added to monoblock type caliper, then actuator integration is achieved, but manufacturing period increases

Engineering Contradiction:
Improveactuator integrationVSAvoidmanufacturing period
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The integrated caliper body design merges multiple brake functions into a single manufacturable component. The caliper body is designed to accommodate both parking and sliding brake operations through its structural configuration, allowing for streamlined manufacturing processes and reduced assembly time compared to separate component approaches.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If conventional caliper structure with multiple components is used, then ease of manufacture is improved, but appearance and rigidity are compromised

Engineering Contradiction:
Improvecomponent assemblyVSAvoidappearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent achieves a monoblock type integrated structure that combines multiple caliper functions into one unified component. This integration provides a sleek, continuous appearance without visible joints or seams, while maintaining manufacturing feasibility through careful design of the unified structure. The single-piece construction enhances both aesthetics and structural rigidity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

While maintaining an integrated appearance, the caliper body is functionally segmented into distinct regions: the parking brake application portion and the sliding brake application portion. This functional segmentation allows each brake type to operate independently within the unified structure, achieving both aesthetic simplicity and functional versatility.

Inventive Principle:
Principle #1Segmentation

4Shape

If monoblock type caliper is manufactured by precisely processing one component, then appearance is improved, but manufacturing cost and period increase

Engineering Contradiction:
ImproveappearanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The integrated caliper body design merges multiple functions into a single component that can be manufactured as one piece. The structure is designed to accommodate both parking and sliding brake mechanisms within the unified body, reducing the need for post-manufacturing assembly operations and associated costs while maintaining the aesthetic benefits of a monoblock construction.

Inventive Principle:
Principle #5Merging (Combining)
