Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing electronic component packages with cylindrical cores require manual removal after complete extraction, deteriorating the workability of automatic mounting processes.

Innovation Solution

The electronic component packages are redesigned with a flat plate-shaped core at one end, allowing the core to be pulled out together with the packaging tape during automatic mounting, eliminating the need for manual removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a cylindrical core is used in the electronic component packaging tape, then the packaging structure is simple and easy to manufacture, but the core remains on the mounter after complete extraction requiring manual removal which deteriorates workability

Engineering Contradiction:

Improveworkability of automatic mountingVSAvoidpackaging structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The packaging structure is segmented into two functional parts: the cylindrical core for winding and storage, and the flat plate-shaped core integrated with the carrier tape for automatic extraction. This segmentation allows each part to perform its specific function optimally without interfering with the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flat plate-shaped core is preliminarily integrated with the carrier tape at one end portion, positioned to protrude from the cylindrical core. This preliminary arrangement ensures that during automatic mounting, the flat plate core is extracted first, guiding the cylindrical core to follow without remaining on the mounter.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the core is integrated with the carrier tape, then automatic extraction is enabled improving workability, but the structure becomes more complex

Engineering Contradiction:

Improveautomatic mounting efficiencyVSAvoidcore structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The flat plate-shaped core is merged with the carrier tape by fixing it to one end portion of the tape. This merging creates a unified structure where the core and tape move together during extraction, enabling automatic mounting without manual intervention.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The core structure transitions from a purely cylindrical form to a composite structure adding a flat plate dimension. This dimensional change allows the core to interact with the mounting equipment in a new way, enabling automatic detection and extraction while maintaining structural simplicity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
