Solution Overview

Problem

Existing home automation devices require complex operation and maintenance, with control systems often involving multiple buttons and interfaces that can be prone to accidental activation and are not user-friendly.

Innovation Solution

A building technology controller utilizing a proximity-sensitive sensor integrated with evaluation electronics, eliminating the need for physical buttons by using a single, seamless input field made of transparent or opaque materials, with a touch panel for enhanced usability and a sleep mode to prevent accidental operation, featuring sensitivity adjustment and a scroll booster for efficient parameter adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons and interfaces are used for control, then the device can provide more functions and controls, but the operation becomes more complex and prone to accidental activation

Engineering Contradiction:
Improvecontrol functionsVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple control buttons are merged into a single touch-sensitive input field. The input field can detect different touch positions, durations, and patterns to provide various control functions, thereby reducing the number of physical buttons while maintaining operational versatility and simplifying the user interface.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single input field serves multiple functions by detecting different touch interactions (position, duration, pattern) to execute various control commands. This multi-functional approach replaces multiple dedicated buttons, reducing complexity while maintaining adaptability across different control scenarios.

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

2Ease of operation

If physical buttons are used for input, then the device is easy to operate, but the housing requires additional components and assembly steps

Engineering Contradiction:
Improveinput mechanismVSAvoidhousing structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mechanical button structure is extracted and replaced with a touch-sensitive sensor integrated directly into the housing panel. This eliminates the need for separate button components, reducing assembly steps and simplifying the housing structure while maintaining ease of operation through direct touch interaction.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mechanical button press system is replaced with an electrical/touch-based sensing system. The input field uses proximity-sensitive or capacitive sensors that detect touch without requiring mechanical movement, thereby eliminating mechanical buttons and simplifying the housing structure.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the control device remains active continuously, then it is always ready for operation, but energy consumption increases

Engineering Contradiction:
ImproveavailabilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The control device alternates between active and sleep states. During normal operation, the device is active and responsive to touch inputs. After a period of inactivity, it automatically transitions to a low-power sleep state, periodically checking for input while conserving energy. This periodic cycling balances availability with energy efficiency.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control device automatically manages its own power state by detecting user inactivity and transitioning to sleep mode without requiring manual intervention. The system self-regulates its availability based on usage patterns, reducing energy consumption while maintaining readiness when needed.

Inventive Principle:
Principle #25Self-service

AI summary

The regulator has a device (10) including an input field (11) with a proximity-sensitive capacitive sensor connected with an evaluation unit. The unit detects a change of an electrical condition of the sensor and outputs a position signal to an electronic circuit. The sensor is arranged behind a hard plate (21) of a housing (20). The plate is closed and is formed as a single piece. The sensor and the evaluation unit are connected with an interface i.e. serial peripheral interface bus, where the regulator is connected with the circuit over another interface i.e. controller area network-bus. An independent claim is also included for a method for regulating and/or controlling a household appliance.
