Solution Overview

Problem

The installation of decorative heads at the ends of electric curtain tracks is hindered by actuators, compromising the aesthetic appearance and practicality of electric curtains.

Innovation Solution

The electric curtain track structure incorporates first and second bending sections on the guiding track main body, allowing decorative panels to extend beyond the track, enabling the installation of decorative heads on the outer sides and concealing the actuator for improved aesthetics and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If actuators are installed at the rear ends of the curtain track to enable electric operation, then the curtain can be automated, but the decorative heads cannot be installed at the two ends of the curtain track and the aesthetic appearance is compromised

Engineering Contradiction:
Improveelectric operationVSAvoidaesthetic appearance
Core Design Contradiction:
Extent of automationVSShape

Solution Approach 1:

The actuator is extracted from its conventional position at the rear end of the curtain track and relocated to the middle section. This extraction resolves the conflict by removing the obstruction from the end positions, allowing decorative heads to be installed while maintaining electric operation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The actuator is positioned within the hollow interior space of the guiding track main body rather than at the external rear end. This dimensional relocation (from external to internal positioning) allows the curtain track to maintain both automation functionality and aesthetic appearance with decorative heads at the ends.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Shape

If decorative heads are installed at the two ends of the curtain track to improve aesthetics, then the visual appeal is enhanced, but the actuators obstruct the installation location

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidinstallation feasibility
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The actuator is extracted from the end positions where decorative heads need to be installed, and relocated to the middle section of the curtain track. This resolves the installation conflict by providing clear end positions for decorative head mounting while maintaining the actuator's functional position.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If the actuator is exposed at the rear end of the curtain track to ensure functionality, then the electric operation is maintained, but the overall aesthetic appearance and quality are affected

Engineering Contradiction:
Improveelectric operationVSAvoidaesthetic appearance
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The actuator is nested within the hollow interior space of the guiding track main body. This nesting arrangement allows the actuator to maintain its electric operation functionality while being concealed from external view, thus resolving the conflict between reliability and aesthetic appearance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The actuator is extracted from the external rear end position and relocated to the internal hollow space of the guiding track main body. This extraction eliminates the visual obstruction while preserving the actuator's functional capabilities for electric curtain operation.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An electric curtain track structure (1) includes a guiding track assembly (10), a first actuator (20), a transmission assembly (30) and a decorative assembly (40). The guiding track assembly comprises a guiding track main body (11) having first and second bending sections (111, 112) opposite from each other. The first actuator is installed on the first bending section. The transmission assembly comprises a transmission cable and first hooks (32). The transmission cable is inserted into said main body and driven by the first actuator to move along said main body. The decorative assembly comprises a decorative panel (41) and decorative heads (42). The decorative panel is attached onto an outer side of said main body. Two ends of the decorative panel protrude out of the guiding track man body for the decorative heads to correspondingly install on two ends of the decorative panel. Consequently, the overall appearance thereof is improved.
