Solution Overview

Problem

Current portable electronic devices, such as notebook computers, require inconvenient disassembly processes for hard-disk modules, as users must remove the bottom cover to access and replace them.

Innovation Solution

An electronic module fixing structure featuring a main body with a track and positioning portion, a sliding component, a rotatable rod, and an elastic component, allowing the electronic module to be easily disassembled by applying force to push the sliding component, which rotates the rod and uses elastic force to slide the module out of the main body.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the hard-disk module is fixed with a cover body on the bottom of the casing, then the module is securely retained, but the disassembly process becomes complex and inconvenient

Engineering Contradiction:

Improvemodule retentionVSAvoiddisassembly convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The fixing structure is divided into separate functional components: a sliding component for positioning, a rod for actuation, and an elastic component for providing force. This segmentation allows each part to perform its specific function independently, enabling simple disassembly while maintaining secure retention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing structure transitions from a static cover body to a dynamic mechanism where the sliding component can move along the track. The rod can rotate to different positions (engaged or disengaged), and the elastic component can compress and extend, enabling the system to switch between secure retention and easy disassembly states.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a simple fixing structure is used, then the disassembly process is convenient, but the module retention reliability may be compromised

Engineering Contradiction:

Improvedisassembly convenienceVSAvoidmodule retention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The elastic component automatically provides the force needed to push the sliding component and rod into the engaged position when the module is inserted. The structure self-actuates during installation without requiring external force, ensuring reliable retention while maintaining simple disassembly operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The sliding component acts as an intermediary between the module and the rod. It translates the insertion motion into rod engagement through its movement along the track, ensuring reliable connection while keeping the overall structure simple and easy to disassemble.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Stability of the object's composition

If the rod is engaged with the positioning portion, then the sliding component is fixed at the first position, but the disassembly operation becomes more complex

Engineering Contradiction:

Improvecomponent positioningVSAvoiddisassembly operation

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

Instead of requiring the user to actively disengage the rod from the positioning portion through complex manipulation, the design inverts the approach: the rod is designed to automatically disengage when the sliding component moves to the second position, simplifying the user operation while maintaining stable positioning during normal use.

Inventive Principle:

Principle #13The other way round (Inversion)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Facilitates simple and easy disassembly of electronic modules by allowing users to push the module away from the main body using the elastic force, reducing maintenance complexity and improving user convenience.

Implementation Method 1

The elastic component is connected between the main body and the sliding component. When the electronic module receives a force to push the sliding component, the rod is rotated relative to the sliding component to drive the end to move away from the positioning portion, and the sliding component slides to a second position by the elastic force of the elastic component to push the electronic module away from the main body.

AI summary

A portable electronic device includes an electronic module and an electronic module fixing structure. The electronic module fixing structure includes a main body, a sliding component, a rod and an elastic component connected between the main body and the sliding component. The main body has a track with a positioning portion. The sliding component is slidably disposed on the main body. The rod is rotatably connected with the sliding component. An end of the rod is adapted to move along the track. When the end is located at the positioning portion, the end and the positioning portion are interfered with each other to position the sliding component. When the electronic module pushes the sliding component, the rod is rotated to drive the end to move away from the positioning portion, and the sliding component pushes the electronic module away from the main body through elastic force of the elastic component.
