Solution Overview

Problem

Existing key duplicating machines require manual operation for opening and closing the casing, which is inefficient and lacks automation, safety, and compactness, with previous motorization solutions being complex and bulky.

Innovation Solution

A motorized and automated mechanism for the casing movement, integrated within the machine, using a rotating body interacting with the internal surface of the casing to facilitate efficient and safe operation, allowing both automated and manual control, and reducing overall dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual operation is used for opening and closing the casing, then the structure remains simple, but the efficiency and automation level are low

Engineering Contradiction:
Improveautomation of casing movementVSAvoidcomplexity of movement mechanism
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The patent replaces complex motorized mechanical systems with a simplified mechanism consisting of a rotating body that directly interacts with the casing's internal surface. This substitution maintains automation functionality while dramatically reducing mechanical complexity and component count.

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

Solution Approach 2:

The invention extracts the essential movement function from complex motorized systems and implements it through a minimal mechanism. By taking out only the necessary elements (rotating body and interaction surface), the solution achieves automation without the burden of complex mechanical assemblies.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If motorized solutions are implemented for casing movement, then automation is achieved, but the device becomes bulky and complex

Engineering Contradiction:
Improveoperational efficiencyVSAvoidoverall dimensions of machine
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The rotating body is positioned within the casing's internal volume, nesting the actuation mechanism inside the existing structure. This eliminates the need for external motors and mechanical assemblies, maintaining compact dimensions while achieving motorized operation.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The mechanism utilizes rotational motion in a different dimensional approach compared to traditional linear motorized systems. The rotating body interacts with the casing through rotational contact, achieving movement through a dimensional change that reduces spatial requirements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Extent of automation

If traditional motorized mechanisms are used, then automation is achieved, but the construction becomes complicated

Engineering Contradiction:
Improveautomated casing controlVSAvoidmanufacturing simplicity
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The rotating body directly engages with the casing's internal surface, allowing the mechanism to self-regulate its movement through the interaction of these two components. This self-service approach eliminates the need for complex control systems, sensors, and multiple actuation components, simplifying both manufacturing and maintenance.

Inventive Principle:
Principle #25Self-service

4Extent of automation

If manual handling is completely replaced by motorized systems, then automation increases, but flexibility and manual intervention capability are lost

Engineering Contradiction:
Improvelevel of automationVSAvoidmanual control capability
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

The mechanism is designed with dynamic characteristics that allow it to respond to both automated control inputs and manual intervention. The rotating body can be actuated by the automated system or manually manipulated, providing operational flexibility while maintaining the capability for full automation when needed.

Inventive Principle:
Principle #15Dynamics
