Solution Overview

Problem

Existing electronic devices lack a detection mechanism to determine if the cover is away from the mounting rack and if the opening of the mounting rack is unobstructed, leading to high detection costs and large space occupation.

Innovation Solution

A detection mechanism comprising a mounting rack, door assembly, first and second movable racks, and a detection assembly that detects whether the cover is away from the mounting rack and if the opening is unobstructed, using a system of interconnected racks and a detection assembly to ensure efficient detection without increasing component count or space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a detection mechanism is added to detect cover status and opening obstruction, then detection reliability is improved, but device complexity and space occupation increase

Engineering Contradiction:
Improvedetection reliabilityVSAvoiddetection mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The door assembly serves multiple functions: it acts as both a protective cover for the mounting rack opening and a detection mechanism component. When the door assembly moves between closed and open positions, it simultaneously protects the opening and triggers detection through its movement, eliminating the need for separate detection components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The door assembly's own movement serves as the detection signal. The system uses the door assembly's positional change (between closed and open states) to automatically indicate whether the cover is away from the mounting rack, without requiring external sensors or additional detection components.

Inventive Principle:
Principle #25Self-service

2Reliability

If a detection mechanism is added to detect cover status and opening obstruction, then detection reliability is improved, but space occupation increases

Engineering Contradiction:
Improvedetection reliabilityVSAvoidspace occupation
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The door assembly serves multiple functions: it acts as both a protective cover for the mounting rack opening and a detection mechanism component. When the door assembly moves between closed and open positions, it simultaneously protects the opening and triggers detection through its movement, eliminating the need for separate detection components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The detection function is merged with the door assembly structure. The door assembly combines the protective covering function with the detection signaling function, where its movement between positions serves both to protect the mounting rack opening and to indicate the cover status, thereby saving space.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the mounting rack opening is made accessible for storage module assembly, then ease of operation is improved, but risk of obstruction increases

Engineering Contradiction:
Improveease of storage module assemblyVSAvoidopening obstruction risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The door assembly is positioned to close the mounting rack opening before storage module assembly begins. This preliminary action of closing the door prevents potential obstructions or contaminants from entering the mounting rack area, while still allowing controlled access when needed for assembly operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting rack opening is segmented by the door assembly, which can be opened to allow access for storage module assembly and closed to prevent obstruction. This segmentation allows the system to provide both easy access when needed and protection when not in use.

Inventive Principle:
Principle #1Segmentation
