Solution Overview

Problem

The existing connection terminal assembled bodies require a cutting process after reflowing, which hampers productivity and increases manufacturing costs due to wasteful material usage and complex shapes, necessitating the development of a solution that allows self-standing placement and soldering without special fixtures.

Innovation Solution

A connection terminal assembled body featuring unit connection terminals with a suction member made of synthetic resin, integrated with a suction surface for automatic machine pickup, and a connection-suction member that omits the need for cutting processes, enabling self-standing soldering on circuit boards without special jigs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a connection terminal assembled body is designed to be automatically placed by a chip mounter, then automation is improved, but a cutting process is required after reflowing which reduces productivity and increases complexity

Engineering Contradiction:
Improveautomatic placementVSAvoidproductivity
Core Design Contradiction:
Extent of automationVSProductivity

Solution Approach 1:

The connection terminal assembled body is segmented into a body portion and a placing portion that are separately formed and then integrated. The placing portion is designed as a distinct component with suction holes for automatic pickup, while the body portion contains the connection terminals. This segmentation allows the placing portion to be removed after placement without requiring cutting of the entire assembled body, thus eliminating the harmful cutting process while maintaining automation capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The placing portion is extracted as a separate functional element from the connection terminal assembled body. It is designed to be temporarily attached for automatic placement purposes only, then removed after the connection terminals are soldered to the circuit board. This extraction eliminates the need to cut the main body structure after reflowing, improving productivity by removing an unnecessary processing step.

Inventive Principle:
Principle #2Taking out (Extraction)

2Extent of automation

If the connection terminal assembled body is formed with a complex shape to enable automatic pickup, then automation is improved, but material waste increases and manufacturing cost rises

Engineering Contradiction:
Improveautomatic pickupVSAvoidmaterial waste
Core Design Contradiction:
Extent of automationVSLoss of substance

Solution Approach 1:

The placed body is divided into a body portion and a placing portion. The placing portion is designed with minimal material required only for the suction function (with suction holes), while the body portion contains the essential connection terminals. This segmentation allows efficient material usage in each component, reducing overall material waste while maintaining automatic pickup capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The placing portion is designed as a temporary, disposable component that serves its purpose during automatic placement and then is removed. It does not need to be durable or complex, only sufficient for the pickup and placement function. This approach reduces material consumption and manufacturing cost compared to designing the entire assembled body with complex shapes for automatic handling.

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

3Ease of operation

If the connection terminal assembled body is designed to stand by itself during soldering, then special fixtures are eliminated improving ease of operation, but placing stability is poor making self-standing difficult

Engineering Contradiction:
Improveease of operationVSAvoidplacing stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The connection terminal assembled body is designed to be self-sufficient during the soldering process. The body portion with its connection terminals and the placed portion work together to provide inherent stability without requiring external fixtures. The design allows the assembled body to stand by itself during reflowing, eliminating the need for special fixation fixtures and improving ease of operation.

Inventive Principle:
Principle #25Self-service

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution improves productivity by eliminating the cutting process, reducing material waste, and simplifying material cutting, thereby lowering manufacturing costs and enhancing self-standing functionality during the reflowing process.

Implementation Method 1

a suction member made of synthetic resin, fixed more to a terminal section side than the bent section, and having a suction surface to be sucked by an automatic machine

Methodology Applied
Scientific EffectSuction: Suction

Implementation Method 2

The soldering of this type of the connection terminal assembled body is generally performed by 'reflowing process'. The 'reflowing process' is a method in which paste-like solder that is called as cream solder is applied to a required place of a wiring pattern of the circuit board in advance, and the connection terminal assembled body is placed thereon and then the soldering is performed by directly heating the circuit board to melt the solder.

Methodology Applied
Scientific EffectSoldering: Soldering

Implementation Method 3

the soldering is performed by directly heating the circuit board to melt the solder

Methodology Applied
Scientific EffectMelting: Melting

AI summary

A unit connection terminal (26) is formed of an adhesion section (29) to be soldered onto a circuit board (21) and extending in a longitudinal direction, a terminal section (30) extending in the direction approximately orthogonal to the adhesion section extending in the longitudinal direction and to be connected to a counterpart-side circuit board, a bent section (31) bent so as to connect the adhesion section and the terminal section, and of a suction member (28) made of synthetic resin, fixed more to the terminal side than the bent section (31), and having a suction surface. More preferably, a projection position where the gravity center position of the entire unit connection terminal is projected toward the adhesion section side is included in the adhesion range of the adhesion section.
