Solution Overview

Problem

Conventional control systems for electrically operated devices, such as electric beds, require multiple buttons and indicators, increasing costs and complexity.

Innovation Solution

A control system with a single button on the first control box for pairing and emergency modes, and a single indicator for power and pairing status, reducing the number of components and enhancing cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple buttons and indicators are installed on the first control box, then the control system can perform pairing and emergency functions, but the cost of the control system increases

Engineering Contradiction:

Improvecontrol functionVSAvoidcost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies multi-functionality by enabling a single button to perform multiple functions: pairing function when input power is available, and emergency function when input power is interrupted. Similarly, a single indicator displays multiple statuses: power status and pairing status. This reduces the number of components needed while maintaining full control functionality.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple buttons and indicators are installed on the first control box, then the control system can perform pairing and emergency functions, but the complexity of the control system increases

Engineering Contradiction:

Improvecontrol functionVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into a single button and multiple indicators into a single indicator. The single button integrates both pairing and emergency functions, while the single indicator consolidates power status and pairing status displays. This merging approach reduces system complexity while preserving all necessary control functions.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single button is designed to be universal, performing pairing function under normal power conditions and emergency function during power interruptions. The single indicator serves multiple purposes by displaying both power status and pairing status, thereby reducing the overall number of components and simplifying the system architecture.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of manufacture

If a single button is used for both pairing and emergency modes, then the cost is reduced, but the ease of operation may be affected

Engineering Contradiction:

ImprovecostVSAvoiduser operation

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The system provides feedback through the single indicator to help users understand the current operational mode. The indicator displays power status and pairing status, giving users clear feedback about the system state before they operate the button. This feedback mechanism reduces ambiguity and makes the single-button interface easier to use despite its dual functionality.

Inventive Principle:

Principle #23Feedback

AI summary

A control system is provided for controlling an electrically operated device. The control system includes a first control box and a second control box. The first control box is equipped with a single button. In case that an input power is normally received and the button is pressed, a pairing process is performed. In case that the input power is interrupted, the second control box is in an emergency mode.
