Solution Overview

Problem

The challenge is to effectively manage cables in electronic devices, such as LCD devices, which often result in a disorganized and unsightly appearance due to the lack of proper cable management solutions in support frames.

Innovation Solution

The electronic device incorporates a rotatable cable management unit within its support frame, featuring a frame body with a cable management recess and hole, where the cable management unit is connected and rotates to limit and organize cables, ensuring they are neatly stored and easily manageable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If cables are not managed appropriately in the support frame, then the support frame structure remains simple, but the cables become disorderly and unsightly

Engineering Contradiction:
Improvecable arrangementVSAvoidsupport frame structure
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The support frame is segmented into functional zones: a cable management recess for storing cables and a cable management hole for cable passage. This segmentation organizes cables into designated areas, improving arrangement without significantly complicating the overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable management recess is nested within the support frame body, creating a compact integrated structure. The rotatable cable management unit is nested within the recess, allowing efficient space utilization while maintaining a simple external frame structure.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If a rotatable cable management unit is added to organize cables, then cable management capability is improved, but the support frame structure becomes more complex

Engineering Contradiction:
Improvecable managementVSAvoidsupport frame structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable management unit is designed to be rotatable rather than fixed, allowing it to dynamically adjust its position. This enables the unit to rotate along with the cable when pulled, providing adaptive cable management that simplifies operation while the rotational mechanism itself adds minimal structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rotatable cable management unit automatically rotates in response to cable movement, eliminating the need for manual adjustment mechanisms. The system serves itself by using the cable's own movement to drive the rotation, improving ease of operation without requiring complex control systems.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the cable management unit is fixed, then the structure is simple, but the cable cannot be smoothly managed when pulled or moved

Engineering Contradiction:
Improvecable movementVSAvoidcable management unit
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable management unit transitions from a fixed to a rotatable design, enabling it to dynamically follow cable movement. When the cable is pulled or moved, the unit rotates accordingly, ensuring smooth cable management without creating sharp bends or stress points that could damage the cable.

Inventive Principle:
Principle #15Dynamics

AI summary

An electronic device (1) includes a support frame (10, 30, 50, 70), an electronic unit (12) and a cable (14). The support frame (10, 30, 50, 70) includes a frame body (100) and a first cable management unit (102). The frame body (100) has a cable management recess (1000) and a cable management hole (1002), wherein the cable management recess (1000) communicates with the cable management hole (1002). The first cable management unit (102) is connected to the frame body (100) and rotatably located in the cable management recess (1000). The electronic unit (12) is disposed on the frame body (100). The cable (14) has a first end (E1) and a second end (E2) opposite to the first end (E1). The first end (E1) is connected to the electronic unit (12) and the second end (E2) passes through the cable management hole (1002) to enter the cable management recess (1000). The first cable management unit (102) limits the cable (14) in the cable management recess (1000). When the cable (14) is pulled to move, the first cable management unit (102) rotates along with the cable (14).
