Solution Overview

Problem

Existing fire control panel modular systems require the use of tools for installation, maintenance, repositioning, and replacement, which can be time-consuming and inconvenient for users.

Innovation Solution

A modular assembly design that allows modules to be easily inserted and removed without tools, using a locking tab mechanism and color-coding for user-friendly identification, where modules are retained by a locking ridge and released by a button press.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fire control panel modular systems use tool-based fastening mechanisms, then the structural stability and reliability of module attachment is improved, but the ease of operation and time required for installation and maintenance deteriorates

Engineering Contradiction:
Improvestructural stability of module attachmentVSAvoidease of installation and maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The fastening mechanism is segmented into separate functional components: a locking ridge on the module and a corresponding locking tab on the carrier. This segmentation allows for simple, tool-free assembly while maintaining secure attachment through the interlocking geometry of these segmented parts.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of requiring a tool to tighten or secure the module, the design inverts the approach by using a spring-loaded locking tab that automatically engages when the module is inserted. The locking action is inverted from requiring external force to being automatically applied through the spring mechanism.

Inventive Principle:
Principle #13The other way round (Inversion)

2Strength

If tool-based fastening mechanisms are used for fire control panel modules, then the strength of module retention is improved, but the time required for installation and maintenance operations increases

Engineering Contradiction:
Improvestrength of module retentionVSAvoidtime for installation and maintenance
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The spring-loaded locking tab is pre-positioned on the carrier, ready to engage automatically when the module is inserted. This preliminary positioning eliminates the need for time-consuming tool-based fastening operations while ensuring strong retention through the pre-loaded spring mechanism.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The locking mechanism is designed to be self-servicing through the spring-loaded tab that automatically engages with the locking ridge when the module is inserted. This self-service mechanism eliminates the need for external tools or manual fastening operations, reducing installation time while maintaining strong module retention.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If simple release mechanisms are used without tools, then the ease of operation for module removal is improved, but the reliability of module retention may deteriorate

Engineering Contradiction:
Improveease of module removalVSAvoidreliability of module retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The locking tab is designed as a dynamic, spring-loaded component that can transition between engaged and disengaged states. This dynamic mechanism provides reliable retention when engaged and easy, tool-free removal when the user activates the release mechanism, satisfying both reliability and ease of operation requirements.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring-loaded locking tab acts as an intermediary between the module and the carrier. It provides a reliable mechanical connection when engaged and serves as a controllable release point when the user activates the release mechanism, enabling both secure retention and easy, tool-free removal.

Inventive Principle:
Principle #24Intermediary (Mediator)
