Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical/electronic installation devices with motion detectors lack flexibility in operating modes, as they typically offer only fully automatic or manual operation, failing to provide customizable options that cater to specific user needs, such as energy-saving and user convenience in various environments.
Innovation Solution
An electrical/electronic installation device with a motion detector and manual switching device that allows customers to set four distinct operating modes: fully automatic, manual, semi-automatic with manual switch-on and automatic switch-off, and semi-automatic with automatic switch-on and manual switch-off, enabling customizable lighting control based on user preferences and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a motion detector with fully automatic operation is used, then energy-saving control is achieved, but user flexibility and manual control capability are reduced
Solution Approach 1:
The system dynamically switches between fully automatic and manual operating modes based on user needs. The operating mode can change from automatic (for energy saving) to manual (for user control) and back, making the system adaptable rather than fixed in one state
Solution Approach 2:
The installation device combines multiple functions in one unit: it can operate as a fully automatic motion-activated switch, as a manual switch, or as a dimmer. This multi-functionality allows a single device to meet different user needs in different situations
2Ease of operation
If a motion detector with automatic operation is used, then convenience is improved, but energy consumption increases due to lack of manual control
Solution Approach 1:
The system allows dynamic switching between automatic and manual modes, enabling users to choose automatic operation for convenience when needed, and manual operation when energy conservation is the priority
3Adaptability or versatility
If manual switching device is added, then operating mode flexibility is improved, but device complexity increases
Solution Approach 1:
The patent combines the motion detector, manual switching device, and dimmer functions into a single integrated installation device. This merging approach provides multiple operating modes without requiring separate devices, thus managing complexity through integration rather than addition

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides enhanced user control and energy management by allowing users to choose operating modes that suit specific contexts, such as automatic lighting in twilight and manual override in dark environments, ensuring energy efficiency and user convenience, with the ability to switch between modes for different settings.
Implementation Method 1
an IR detector/lens arrangement 3 (possibly including a mirror for deflecting IR radiation) with a pyroelectric infrared sensor (preferably dual sensor) and preferably a Fresnel lens for the detection of IR radiation
Implementation Method 2

Implementation Method 3
preferably a Fresnel lens for the detection of IR radiation from a 'moving' heat source in a wide detection range (preferably 180°)
Implementation Method 4

AI summary
An electrical/electronic installation device with a motion detector microprocessor (2) is proposed, which controls a switching element (9) for a lighting device on its output side, and which receives signals on its input side from an IR detector/lens arrangement (3), a daylight sensor (5), a time setting (6) for specifying a switch-off delay, a twilight setting (7) for specifying a light level below which the device should operate, and a manual switching device (8). It is important that the time setting (6) can be set to an infinitely long switch-off delay and that the twilight setting (7) can be set to an infinitely low light level.In this way, the device can be advantageously set by the customer to four different operating modes: a fully automatic operating mode specified or controlled by the motion detector, a manual operating mode specified by the manual switching device, a semi-automatic operating mode with manual switching on by actuating the switching device and automatic switching off by the motion detector, and a semi-automatic operating mode with automatic switching on by the motion detector and manual switching off by actuating the switching device.
