Solution Overview

Problem

Digital photo frames with external power requirements face inconvenience in adjusting their hanging height due to the fixed length of power cables, which restricts flexibility in installation and adjustment.

Innovation Solution

A fixing structure that provides both mechanical and electrical connection, allowing an electrical wire to support and power the device while enabling adjustable height settings through a piercing mechanism and sliding components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed-length power cable is used to connect the digital photo frame, then the electrical connection is simple and reliable, but the adjustability of hanging height is lost

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidhanging height adjustability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The power cable is divided into multiple segments or sections that can be independently adjusted. The fixing device includes multiple positioning points along the cable length, allowing the cable to be segmented into adjustable sections that maintain electrical connection while enabling height adjustment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fixing device transitions from a static fixed-position connector to a dynamic adjustable connector. The device allows the power cable to move between multiple fixed positions while maintaining reliable electrical contact, providing both stability and adaptability.

Inventive Principle:

Principle #15Dynamics

2Device complexity

If a simple support structure is used, then the device complexity is reduced, but the ability to provide both mechanical support and electrical connection is compromised

Engineering Contradiction:

Improvesupport structure complexityVSAvoidintegrated support and power function

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The fixing device merges the mechanical support function and electrical connection function into a single integrated component. The bracket or hanger structure incorporates built-in terminal blocks or connectors, combining structural support with power delivery without requiring separate mounting hardware.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The fixing device is designed to perform multiple functions simultaneously: providing mechanical support, enabling height adjustment, and establishing electrical connection. This multi-functional design reduces the need for separate components while increasing versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If wire end terminals and terminal blocks are used for connection, then the electrical connection is secure, but the flexibility to adjust hanging height is restricted

Engineering Contradiction:

Improveelectrical connection strengthVSAvoidheight adjustment convenience

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

An intermediary adjustable connector is introduced between the power cable and the digital photo frame. This intermediary device maintains secure electrical connection through built-in terminal blocks while providing the flexibility to adjust hanging height, mediating between the need for secure connection and height adjustability.

Inventive Principle:

Principle #24Intermediary (Mediator)
