Solution Overview

Problem

Existing household appliances with additional functionalities, such as lighting and sensors, have complex structures due to separate installation of electrical components, requiring additional openings in the housing that complicate design and manufacturing.

Innovation Solution

Integrating the light source, sensor unit, and connection unit into a common lighting module with a carrier, such as a circuit board, which simplifies the structure and manufacturing by using a single connection unit for both light sources and sensors, eliminating the need for separate openings in the appliance housing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If electrical and electronic components for additional functionalities are installed separately in the housing, then each component can be independently installed and maintained, but the design becomes complex and requires separate openings in the housing

Engineering Contradiction:
Improveease of manufactureVSAvoiddesign complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple electrical and electronic components (light source, sensor unit, connection unit) into a single integrated lighting module. This merging eliminates the need for separate installations and reduces design complexity while maintaining ease of manufacture through modular assembly.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting module serves multiple functions: it provides lighting through the light source, environmental sensing through the sensor unit, and electrical connection through the connection unit. This multi-functionality reduces the number of separate components needed in the housing.

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

2Adaptability or versatility

If separate openings are provided in the housing for each component, then each component can access the environment or appliance interior, but the housing design becomes more complex

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidhousing design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

By combining the light source, sensor unit, and connection unit into a single lighting module, the patent reduces multiple separate openings in the housing to a single opening or integrated access point, thereby maintaining component accessibility while simplifying housing design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent positions the sensor unit on the side of the carrier facing the housing opening, allowing the sensor to detect environmental conditions through the same opening used for lighting, effectively utilizing the same spatial dimension for multiple functions.

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

3Adaptability or versatility

If multiple separate components are installed in the housing, then each functionality can be independently implemented, but the space requirements and manufacturing complexity increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent integrates the light source, sensor unit, and connection unit onto a single carrier board, allowing all functionalities to be manufactured together as one module. This reduces manufacturing complexity while maintaining full functionality and adaptability.

Inventive Principle:
Principle #5Merging (Combining)
