Solution Overview

Problem

Existing rack systems lack a secure and easy-to-use mechanism for attaching and detaching support brackets from support rails, leading to potential unintentional detachment or attachment issues.

Innovation Solution

A rack system with axially extending bracket arresting slots and corresponding locking locations, featuring a support bracket with axially disposed engaging hooks and a locking mechanism comprising a locking plunger that can be actuated to engage with locking locations on the support rail, preventing unintentional detachment or attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a locking mechanism with locking plunger is added to prevent unintentional detachment, then the reliability of bracket attachment is improved, but the device complexity increases

Engineering Contradiction:
Improveattachment securityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking plunger is spring-loaded to automatically engage with the locking location when the bracket is installed, providing self-locking functionality without requiring additional actuators or complex control mechanisms. The spring bias ensures the plunger projects into the locking location by default, creating a passive safety feature.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking plunger is designed to be movable between a retracted position (for installation/removal) and a projected locked position (for secure attachment). This dynamic element allows the system to transition between states of freedom and constraint, providing both ease of installation and secure operation.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If engaging hooks are used to attach brackets to support rails, then the ease of operation for mounting and demounting is improved, but the risk of unintentional sliding displacement increases

Engineering Contradiction:
Improvemounting easeVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The attachment function is divided into two independent components: engaging hooks for easy mounting/demounting operations, and a locking plunger with locking location for preventing unintentional detachment. This segmentation allows each component to optimize its specific function without compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The locking plunger is pre-positioned in a projected state that engages with the locking location immediately upon bracket installation, providing automatic protection against unintentional detachment before any operational forces are applied to the bracket.

Inventive Principle:
Principle #10Preliminary action
