Solution Overview

Problem

Existing computer casing assembly methods require screws for fixing components, making the process labor-intensive and inflexible, with fixed cubical cartridges that cannot be easily assembled or disassembled or reconfigured.

Innovation Solution

A block-shape container system that can be assembled and disassembled from a computer casing without screws, featuring a latching mechanism with flexible positioning options, using a press plate and spring leaves for secure locking and easy release, allowing vertical or horizontal configuration of cartridges.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to fix components into cartridges, then the components are securely fixed, but the assembly and disassembly process becomes labor-intensive and time-consuming

Engineering Contradiction:
Improvesecure fixationVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces the traditional screw-based mechanical fastening system with a spring-loaded latch mechanism. The latch engages with slots in the cartridge to provide secure fixation, while the spring enables quick release by simply pressing the latch, eliminating the need for tools and significantly reducing assembly and disassembly time.

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

Solution Approach 2:

The latch mechanism is designed to be self-latching through the spring force, which automatically engages the latch with the cartridge slots upon insertion. This self-service mechanism eliminates the need for manual screw tightening and ensures reliable fixation without additional operational steps.

Inventive Principle:
Principle #25Self-service

2Ease of manufacture

If cartridges are designed in fixed cubical shape, then manufacturing is simplified, but flexibility in positioning and configuration within the computer casing is reduced

Engineering Contradiction:
Improvecartridge manufacturingVSAvoidpositioning flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic positioning capability through the latch mechanism that can engage with multiple slots at different orientations. While the cartridge maintains its simple cubical shape for ease of manufacture, the latch can secure the cartridge in various positions (vertical, horizontal, angled) within the computer casing, providing adaptability without complicating the cartridge design.

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple components are installed one by one into separate cartridges, then each component is individually protected, but the overall assembly process becomes complex and time-consuming

Engineering Contradiction:
Improvecomponent protectionVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges multiple individual cartridge installation operations into a single unified latch engagement action. The computer casing is designed with a common latch mechanism that can simultaneously secure multiple cartridges inserted into the casing, transforming the sequential one-by-one installation process into a parallel operation that significantly reduces total assembly time while maintaining individual component protection.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A block-shape container which can be assembled into and disassembled from a computer casing, is composed of a block-shape container; a computer casing, a side of which is provided with a locking slot, with ear parts being located above the insertion slot, with the ear parts being provided with shaft holes, and with an upper wall of the insertion slot being provided with insertion holes; and a press plate, two sides of which are provided with shaft ends to be loosely connected into the shaft holes, a front end of which is formed downward with a projection part for locking; After the container is inserted into the insertion slot, such that the container, which is latched with the cartridges, can be locked on the computer casing without using screws, and can be quickly assembled or disassembled.
