Solution Overview

Problem

Existing curtain hanging systems face challenges due to inaccurate dimension measurements, leading to failed installations and resource waste, as the length of the hanging rod often does not match the width of the installation location, resulting in oversized gaps.

Innovation Solution

A telescopic hanging rod with a mechanism comprising a first and second telescopic connecting portion, coaxially arranged, and a locking mechanism that allows for adjustable length, ensuring compatibility with varying installation spaces and facilitating standard batch production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed-length hanging rod is used, then the manufacturing process is simple, but the rod length cannot match the installation location width, causing installation failure or resource waste

Engineering Contradiction:
Improverod length adaptabilityVSAvoidrod structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The hanging rod is divided into multiple telescopic sections that can slide relative to each other. Each section is a separate component that can move independently, allowing the overall rod length to be adjusted to match different installation locations while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hanging rod transitions from a fixed-length static structure to a dynamic adjustable structure. The telescopic sections can slide to change the rod length, and the locking mechanism allows the rod to be fixed at the desired length, providing both adaptability and structural stability.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a telescopic mechanism is added to adjust rod length, then the rod can adapt to different installation locations, but the structure becomes more complex

Engineering Contradiction:
Improverod length adjustabilityVSAvoidtelescopic mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The telescopic sections are nested within each other, with smaller sections inside larger ones. This nesting arrangement allows multiple adjustable sections to be compact when retracted and provides a straightforward structural configuration that reduces overall complexity compared to alternative telescopic designs.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The locking mechanism is designed to be operated by the user through simple action (such as pushing or pulling), and the telescopic sections lock into place automatically at predetermined positions without requiring additional tools or complex control systems. This self-servicing approach minimizes operational complexity.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If customized production is used for each installation location, then the rod length matches the location precisely, but measurement errors occur and production costs increase

Engineering Contradiction:
Improverod length precisionVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

Instead of customizing each rod to a specific length, the invention provides a single rod design that can change its length parameter through the telescopic mechanism. The rod can be adjusted to various standard lengths and locked at the required dimension, achieving precise fit without requiring customized production for each installation location.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

A single telescopic rod design serves multiple functions and can be used for various installation locations with different width requirements. This universal design eliminates the need for separate customized rods for each location, reducing measurement errors and improving production efficiency through standardized manufacturing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Productivity

If standard batch production is adopted, then production cost and efficiency improve, but the rod length may not precisely match non-standard installation locations

Engineering Contradiction:
Improvebatch production efficiencyVSAvoidrod length precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The standardized telescopic rod maintains batch production efficiency while incorporating dynamic adjustability. The rod can be manufactured in standard configurations but allows precise length adjustment during installation through the telescopic mechanism, combining the benefits of standardized production with precise fit for various installation locations.

Inventive Principle:
Principle #15Dynamics

AI summary

A telescopic hanging rod for a curtain fabric is disclosed, which comprises a hanging rod body (1) and a telescopic mechanism arranged on at least one end of the hanging rod body (1); the telescopic mechanism comprises a first telescopic connecting portion (2) connected to the hanging rod body (1), and a second telescopic connecting portion (3) slidably connected with the first telescopic connecting portion (2); the first telescopic connecting portion (2) and the second telescopic connecting portion (3) are coaxially arranged. With the aforementioned structure, the length of the hanging rod is adjustable through the sliding of the first telescopic connecting portion (2) and the second telescopic connecting portion (3) which are in slidable connection, therefore, the length of the hanging rod can be adjusted to a certain degree in accordance with the size of the mounting space during the mounting process, thereby lowering difficulty in dimension measurement prior to installation. Besides, the width of a curtain fabric is also adjustable, hence, standard batched production is achieved, while the production scale is enlarged, and the production cost reduced.
