Solution Overview

Problem

Installing an illuminated bathroom mirror with a mains power supply is costly and time-consuming due to the need for cabling and electrical expertise, as building regulations restrict the provision of mains power sockets in bathrooms.

Innovation Solution

An illuminated mirror with a self-contained power supply featuring a rechargeable battery unit and bi-stable mechanism for easy mounting and removal, along with a splash-resistant seal, allowing for tool-free installation and concealed integration within the mirror frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mains power supply is used for illuminated mirror, then reliable power supply is achieved, but installation complexity and cost increase due to cabling requirements

Engineering Contradiction:
Improvepower supply reliabilityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The power supply system is segmented into separate functional modules: a rechargeable battery unit housed in a removable power supply unit, and a mounting structure integrated into the mirror frame. This segmentation allows the power supply to be installed without complex cabling, as the battery unit can be simply inserted and secured into the mounting structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The power supply unit is extracted as a self-contained module that can be installed independently of the mirror assembly. The battery and electrical connector are housed together in a removable unit that interfaces with the mirror frame through a standardized mounting structure, eliminating the need for permanent electrical installations.

Inventive Principle:
Principle #2Taking out (Extraction)

2Duration of action of stationary object

If mains power supply with cabling is installed, then continuous power is provided, but installation time and cost increase due to tiling and wiring work

Engineering Contradiction:
Improvecontinuous power supplyVSAvoidinstallation time
Core Design Contradiction:
Duration of action of stationary objectVSLoss of time

Solution Approach 1:

The power supply unit is designed as a pre-assembled module containing the battery, electrical connector, and mounting interface. This preliminary preparation allows the installer to simply insert the complete unit into the mirror frame without performing complex installation tasks such as routing cables through walls or connecting electrical wiring.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If power supply unit is made removable for easy installation, then installation ease is improved, but connection reliability may worsen

Engineering Contradiction:
Improveinstallation easeVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The electrical connector and mechanical mounting structure are merged into a single integrated component. When the power supply unit is inserted into the mirror frame, the same physical action simultaneously establishes both the mechanical attachment and the electrical connection, ensuring that connection reliability is maintained while preserving ease of installation and removal.

Inventive Principle:
Principle #5Merging (Combining)
