Solution Overview

Problem

Existing methods for producing ball spreaders are limited by slow production velocity and require significant space due to manual assembly and separate supply lines for multiple parts.

Innovation Solution

A method involving moulding of a plastic ball housing and cover, where the ball is positioned under pressure within the mould, and the cover is connected using an actuator, allowing for assembly within the mould and reducing the need for manual labor and space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual assembly is used to assemble the ball, ball housing, and cover, then the production process is simple and flexible, but the production velocity is slow and depends on the number of operators

Engineering Contradiction:
Improveproduction velocityVSAvoidassembly process complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the ball, ball housing, and cover assembly operations into a single integrated mould. The mould contains multiple cavities that simultaneously form all three components and automatically assemble them through the mould's internal mechanism, eliminating the need for separate manual assembly steps and significantly increasing production velocity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single mould serves multiple functions: it forms the ball housing, forms the cover, positions the ball, and performs the assembly operation all in one device. This multi-functional approach replaces what would traditionally require multiple separate tools and manual operations

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

2Area of stationary object

If separate supply lines are used for ball, ball housing, and cover, then each component can be manufactured independently, but the production space required is large due to multiple supply lines and assembly zone

Engineering Contradiction:
Improveproduction spaceVSAvoidcomponent manufacturing independence
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The patent merges multiple manufacturing operations into a single mould location. All three components are formed and assembled within the same mould body, eliminating the need for separate supply lines and reducing the production footprint to just the mould and its immediate support structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mould design nests multiple cavities and assembly features within a single compact structure. The ball housing cavity, cover cavity, and ball positioning mechanism are all integrated within the mould body, creating a space-efficient configuration that produces multiple components in one location

Inventive Principle:
Principle #7Nested doll (Nesting)
