Remote Appliance Control Triggered by Closed-Door Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical household appliances, such as washing machines, require manual activation of a remote control facility and closure of the door for remote operation, leading to potential user forgetfulness and safety concerns.
Innovation Solution
An electrical household appliance with a communication interface, remote control facility, door monitoring system, and controller that automatically activates the remote control facility when the door is closed and the appliance is locally activated, allowing remote operation while ensuring safety standards are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual activation of remote control facility is required, then safety is improved, but user convenience deteriorates due to potential forgetfulness
Solution Approach 1:
The system performs preliminary action by automatically activating the remote control facility when the door is closed, before any remote operation is attempted. This eliminates the need for users to manually activate the facility and remember to do so, while still maintaining safety through the door state verification.
2Ease of operation
If remote control facility is automatically activated, then user convenience is improved, but safety deteriorates due to potential accidental operation
Solution Approach 1:
The system applies local quality by making the automatic activation conditional on the door being in the closed state. This creates a spatial condition that must be met before remote control becomes available, preventing accidental operation while maintaining convenience for legitimate use cases.
3Reliability
If additional operating elements are added for remote control activation, then safety is improved, but device complexity increases
Solution Approach 1:
The system implements self-service by using the existing door state information to automatically control the remote control facility activation. The door state monitoring system already exists for safety purposes, and it now also serves to control remote access, eliminating the need for separate activation buttons or switches.
