Solution Overview

Problem

Current fire protection and alarm systems face challenges in providing real-time feedback on signal strength during installation, leading to time-consuming and often inefficient assembly processes due to the reliance on external equipment or communication between multiple installers.

Innovation Solution

A wireless component with a measuring device to assess signal strength, an evaluation device to generate a signal strength value, and an output interface for local display, allowing installers to directly visualize signal quality and adjust assembly conditions accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If wireless components rely on external equipment or communication between multiple installers to provide signal strength feedback, then the system can function, but the assembly process becomes time-consuming and inefficient

Engineering Contradiction:
Improveassembly speedVSAvoidinstallation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The wireless component performs self-diagnosis by automatically measuring its own signal strength and displaying it locally without requiring external equipment or multiple installers. The component serves itself by providing real-time feedback on assembly conditions, eliminating the need for external measurement devices and reducing coordination overhead between installers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The component provides real-time feedback on signal strength through a local display interface, allowing installers to immediately see the effect of their assembly actions. This continuous feedback loop enables rapid adjustment of assembly conditions without waiting for external measurement systems or multiple communication cycles between installers.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If wireless components continuously monitor and display signal strength, then real-time feedback is provided, but energy consumption increases

Engineering Contradiction:
Improvereal-time feedback capabilityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The measuring device and display operate periodically rather than continuously, activating only when needed to provide real-time feedback during critical assembly phases. This periodic operation maintains the benefit of immediate signal strength information while significantly reducing overall energy consumption compared to continuous monitoring.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system dynamically adjusts its operational state based on assembly needs, transitioning between active measurement/display modes and low-power standby modes. This dynamic behavior allows the component to provide real-time feedback when required while conserving energy during periods when continuous monitoring is not necessary.

Inventive Principle:
Principle #15Dynamics
