Solution Overview

Problem

Existing bait coating containers for angling are complex, prone to component loss, difficult to clean, and costly due to multiple parts, and inefficient in liquid drainage.

Innovation Solution

A single-piece container with integral drainage formations, such as protruded portions and troughs, allows bait to steep in liquid while excess drains away, simplifying manufacturing and cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple independent components (container and removable colander) are used, then liquid drainage function is provided, but device complexity increases and components can be misplaced or lost

Engineering Contradiction:
Improvecomponent retentionVSAvoidnumber of components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the container and colander into a single integrated device where the drainage formation is formed as an integral part of the container base. This eliminates the need for separate removable colanders while maintaining the drainage function, directly resolving the contradiction between component retention and device complexity.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If multiple independent components with complex geometry are used, then drainage function is achieved, but cleaning difficulty increases

Engineering Contradiction:
Improvedrainage functionVSAvoidcleaning ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By merging the container and drainage structures into a single piece with integral drainage formations, the patent eliminates multiple components and complex geometries that are difficult to clean. The integrated design allows for simpler, more thorough cleaning while maintaining effective drainage functionality.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If multiple independent components are used, then drainage capability is provided, but manufacturing cost and complexity increase

Engineering Contradiction:
Improvedrainage capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent integrates the drainage formation directly into the container base as a single molded piece, eliminating the need to manufacture and assemble multiple separate components. This single-piece construction reduces manufacturing steps, assembly requirements, and overall production costs while maintaining full drainage capability.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If integral drainage formations are used, then manufacturing is simplified, but bait support and liquid drainage coordination must be achieved

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidinternal structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies local quality by creating specific protruded portions and trough portions at strategic locations within the integral drainage formation. These localized structural variations provide bait support surfaces and drainage pathways without requiring complex overall device architecture, achieving both manufacturing simplicity and functional effectiveness.

Inventive Principle:
Principle #3Local quality
