Solution Overview

Problem

Conventional terminal crimping machines are bulky and expensive due to the need for a separate applicator and tight tolerances, which limits space around the crimping zone and makes it difficult to integrate components like cameras or sensors for monitoring.

Innovation Solution

A crimp tooling system that eliminates the need for a separate applicator by directly coupling the upper and lower tooling to the terminator ram, allowing for improved adaptability and reduced bulk, with the upper tooling supported by the lower tooling assembly during storage and operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate applicator with housing is used to hold crimp tooling, then the tooling is supported and positioned, but the housing occupies much space around the crimping zone making it difficult to place monitoring components

Engineering Contradiction:
Improvetooling support and positioningVSAvoidspace around crimping zone
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent extracts the applicator housing from the crimping system, eliminating the bulky housing that occupied space around the crimping zone. The crimp tooling (anvil and wire crimper) is now directly supported by the terminator frame and ram, with no intervening applicator housing, thereby freeing up space for monitoring components like cameras and sensors.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The terminator frame and ram are made to directly support the crimp tooling functions previously handled by the separate applicator. The terminator ram directly positions and moves the wire crimper relative to the anvil, combining the functions of the terminator and applicator into a single integrated system.

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

2Manufacturing precision

If tight tolerances are used for locating the wire crimper relative to the anvil, then positioning precision is improved, but manufacturing cost increases

Engineering Contradiction:
Improvewire crimper positioning relative to anvilVSAvoidmanufacturing cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent segments the positioning function into two parts: coarse positioning is achieved through the terminator frame's built-in features, while fine positioning is achieved through adjustable mounting mechanisms for the wire crimper and anvil. This allows tight tolerances to be achieved only where necessary, reducing overall manufacturing complexity and cost.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces intermediary positioning features such as adjustable mounts and alignment mechanisms between the terminator ram and the crimp tooling. These intermediaries provide precise positioning without requiring the entire system to be manufactured to tight tolerances, thereby reducing manufacturing cost while maintaining positioning precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If an intervening applicator is used between the terminator ram and crimp tooling, then the tooling is supported, but the system bulk increases and adaptability decreases

Engineering Contradiction:
Improvetooling supportVSAvoidadaptability to different applications
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent removes the intervening applicator from between the terminator ram and the crimp tooling. The wire crimper and anvil are now directly mounted to the terminator frame and ram, eliminating the applicator's housing and components. This reduction in system bulk enhances adaptability by allowing easier integration of monitoring components and greater flexibility for different crimping applications.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If a bulky applicator housing is used, then crimp tooling is supported, but it becomes expensive to manufacture due to tight tolerances requirements

Engineering Contradiction:
Improvecrimp tooling supportVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent extracts and eliminates the bulky applicator housing, supporting the crimp tooling directly through the terminator frame and ram. This eliminates the need for the housing's tight tolerance features, significantly reducing manufacturing cost while maintaining adequate tooling support through the terminator's own structural features.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Crimp tooling (100) includes upper tooling (126) for forming a terminal (120) around a wire (122) during crimping. The upper tooling includes a wire crimper (140) and a wire crimper holder (142) for holding the wire crimper. The wire crimper holder is removably coupled directly to a terminator ram (136) of a terminal crimping machine (102) and being driven by the terminator ram. The crimp tooling includes lower tooling assembly (128) for supporting the terminal during crimping. The lower tooling assembly includes a base (152) having a plate (300) and an anvil (150) supported by the plate. The base is removably coupled directly to the terminal crimping machine.
