Solution Overview

Problem

Existing flush-type control devices for electric user appliances require replacement of the entire device upon failure of either the user interface or actuation circuits, leading to high maintenance costs and bulkiness due to the integration of both components in a single box-shaped body.

Innovation Solution

A control device comprising a separable interface module and actuation module connected via a communication BUS, allowing for modular replacement and configuration, with each module housed in a distinct box-shaped body, enabling flexible installation and maintenance without the need for a single, integrated unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the interface means and actuation circuits are integrated in the same box-shaped body, then the device has a compact form factor, but it requires replacement of the entire device upon failure of either component, leading to high maintenance costs

Engineering Contradiction:
Improvedevice volumeVSAvoidmaintenance cost
Core Design Contradiction:
Volume of moving objectVSEase of repair

Solution Approach 1:

The control device is divided into two separate modules: a first module housing the interface means and a second module housing the actuation circuits. Each module can be independently replaced, allowing cost-effective maintenance by replacing only the faulty module rather than the entire device.

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the interface means and actuation circuits are separated into distinct modules, then maintenance becomes simpler and less expensive, but the device has greater bulk requiring space for mounting two separate bodies

Engineering Contradiction:
Improvemaintenance simplicityVSAvoidmounting space
Core Design Contradiction:
Ease of repairVSVolume of moving object

Solution Approach 1:

The first and second modules are designed to be nested within a single box-shaped body, with each module occupying a separate compartment or space. This nesting arrangement allows the separated modules to be mounted within the volume of a single flush-mounted box, avoiding the need for additional mounting space while maintaining modular replaceability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If two separate modules are used with microprocessors in both interface and actuation modules, then modular replacement is enabled, but the device becomes very expensive

Engineering Contradiction:
Improvemodular replacement capabilityVSAvoiddevice cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The microprocessor is extracted from the actuation module and relocated to the interface module. The actuation module contains only the actuation circuits without a microprocessor, while the interface module houses both the interface means and the microprocessor. This extraction reduces the complexity and cost of the actuation module while maintaining modular replacement capability.

Inventive Principle:
Principle #2Taking out (Extraction)
