Solution Overview

Problem

Conventional water heating apparatus installation is complicated due to the need for manual verification of remote control units and communication line connections, requiring operators to confirm the number and correct installation of remote control units across multiple locations.

Innovation Solution

A water heating apparatus with a device body featuring a connection-number counter and display unit within its outer casing, allowing for the determination and visible indication of connected remote control units upon powering up, simplifying the installation process by providing a visual confirmation of the number of connected units through an external window.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device body is connected to multiple remote control units through communication lines, then the functionality and control capability are improved, but the installation verification process becomes more complex and time-consuming

Engineering Contradiction:
Improvecontrol capabilityVSAvoidinstallation verification process
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device body includes a connection-number counter that automatically counts and displays the number of connected remote control units through a display unit visible from the exterior. This feedback mechanism allows installation operators to verify connections without manually checking each communication line, thus resolving the contradiction between enhanced control capability and complex verification process

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-verification by automatically counting and displaying the number of connected remote control units. The connection-number counter and display unit enable the device to inform operators about connection status without external intervention, simplifying the installation process while maintaining multi-unit control capability

Inventive Principle:
Principle #25Self-service

2Measurement precision

If the installation operator manually checks each remote control unit location, then the connection accuracy is improved, but the installation time and operational complexity increase

Engineering Contradiction:
Improveconnection accuracyVSAvoidinstallation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The display unit provides immediate feedback on the number of connected remote control units, allowing operators to verify installation completeness in seconds rather than manually checking each location. This maintains connection accuracy while dramatically reducing installation time

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The manual mechanical verification process of physically checking each remote control unit location is replaced by an electronic counting and display system. The connection-number counter automatically tracks connections, substituting the time-consuming manual inspection with an instant electronic readout visible through the window

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