Solution Overview

Problem

Conventional component supply devices are complex, costly, and inefficient due to the need for air pressure systems and multiple tiered tube structures, making it difficult to detect empty tubes and replace them efficiently, especially when handling various types and sizes of components.

Innovation Solution

A component supply device that uses a weight ball to slide components along an inclined stick by gravity, with a sensor detecting the weight ball's position to signal when the stick is empty, allowing for automatic or manual replacement without air pressure, and a versatile stick design that supports components stably across different sizes and types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If air pressure is used to press components in the supplying direction, then components can be reliably supplied, but the device structure becomes complex and size increases

Engineering Contradiction:
Improvecomponent supply reliabilityVSAvoiddevice structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the air pressure generating portion, air pressure supply route, and air pressure switching/adjusting portion from the component supply device. Instead of using air pressure to move components, the invention uses a weight ball that rolls down an inclined stick to directly push components along the supply path, thereby simplifying the device structure while maintaining reliable component supply.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the pneumatic system (air pressure generation and control) with a simple mechanical system consisting of an inclined stick and a weight ball. The weight ball converts gravitational potential energy into kinetic energy to push components, eliminating the need for complex air pressure control mechanisms while achieving reliable component movement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If multiple tiers tubes are arranged to supply different connector types, then various connectors can be supplied, but it becomes difficult to detect empty tubes and replace them efficiently

Engineering Contradiction:
Improveconnector type versatilityVSAvoidempty tube detection difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent introduces a weight ball as an intermediary element in each stick. The weight ball serves as a visual and functional indicator: when present at the bottom of the stick, it indicates the stick is not empty; when absent, it signals the stick is empty and needs replacement. This intermediary makes empty tube detection immediate and obvious without requiring complex sensors or inspection systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

While not explicitly using color changes, the patent employs a visual indication principle where the presence or absence of the weight ball (a distinct physical object) provides immediate visual feedback about the stick's status. This simple visual indicator system allows operators to quickly identify which sticks need replacement among multiple tiers.

Inventive Principle:
Principle #32Color changes

3Productivity

If air pressure systems are included in the component supply device, then components can be pressurized and moved, but the cost of the device increases

Engineering Contradiction:
Improvecomponent movement capabilityVSAvoiddevice manufacturing cost
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent replaces expensive, complex air pressure systems with inexpensive mechanical components - specifically, simple inclined sticks and weight balls. These mechanical elements are much cheaper to manufacture and install than pneumatic systems, while still achieving the necessary component movement functionality. The weight ball acts as a simple, low-cost actuator that eliminates the need for costly air pressure infrastructure.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
