Solution Overview

Problem

Conventional exchangeable plug systems require bulky appliance housings or adjustable prong orientations to accommodate various country-specific connectors, leading to increased product variety and space inefficiencies.

Innovation Solution

An intermediate adapter with a base plate featuring first and second contact elements oriented at non-zero angles, allowing for adjustable pin orientation of the connector unit relative to the appliance, thereby reducing bulkiness and maintaining flexibility across different connector types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If appliance housings with differently oriented universal inputs are manufactured, then multi-directional plug orientation is achieved, but product variety increases

Engineering Contradiction:
Improvemulti-directional plug orientationVSAvoidproduct variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

An intermediate adapter is introduced as a mediator component between the appliance and the connector unit. The adapter includes a base plate with contact elements that can be oriented at different angles (e.g., 0°, 45°, 90°, 135°) relative to the appliance housing, allowing the connector unit to be attached in multiple orientations without requiring multiple appliance housing variants. This single adapter design resolves the contradiction by providing orientation flexibility while maintaining a unified appliance product line.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If connector units with adjustable prong orientation are used, then multi-directional plug orientation is achieved, but the connector units become bulky

Engineering Contradiction:
Improveprong orientation adjustabilityVSAvoidconnector unit size
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The system is segmented into three independent components: the appliance housing, the intermediate adapter, and the connector unit. The orientation adjustment functionality is isolated to the intermediate adapter, which acts as a separate segment between the fixed appliance and the standard connector unit. This segmentation allows the connector unit to remain compact and simple while the adapter provides the necessary orientation flexibility through its rotatable or adjustable contact elements.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If appliance housings are made bulky to accommodate various connectors, then compatibility is improved, but space requirements increase

Engineering Contradiction:
Improveconnector compatibilityVSAvoidappliance housing size
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The intermediate adapter serves as a mediator that enables various country-specific connector units to be compatible with a standardized appliance housing. Instead of enlarging the appliance housing to accommodate different connector types and orientations, the adapter is attached to the housing's universal input and provides the necessary adaptation. This approach maintains a compact appliance design while achieving broad connector compatibility through the intermediary adapter component.
