Solution Overview

Problem

Existing outdoor sliding door awnings face issues such as difficult assembly due to misaligned hole positions, noisy operation, asymmetrical structure, complex mounting, exposed screws, redundant reinforcement, and non-interchangeable chute pipes, leading to cumbersome processing and appearance issues.

Innovation Solution

The design features symmetrical vertical sliding door side frame pipes with aligned holes and slots, non-metal pieces with guiding holes for easy assembly, hidden fasteners, single-sided reinforcement, and separate chute pipes, along with groove portions for aesthetics and simplified manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional asymmetrical vertical sliding door side frame pipes are used, then the structure can provide necessary support, but the processing technology becomes complicated and assembly is difficult

Engineering Contradiction:
Improveprocessing technologyVSAvoidstructure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies asymmetry in reverse by making the vertical sliding door side frame pipes symmetrical in structure. Both left and right vertical pipes have identical hole positions and slot locations, eliminating the need for different processing techniques for different sides. This symmetrical design simplifies manufacturing while maintaining the necessary structural support function.

Inventive Principle:
Principle #4Asymmetry

2Ease of operation

If four side frame pipes are assembled with screw fixation, then the structure can be securely connected, but hole alignment becomes difficult and assembly is troublesome

Engineering Contradiction:
ImproveassemblyVSAvoidhole position alignment
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent implements self-aligning features through slots and guide holes that automatically align during assembly. The slots in the vertical pipes and corresponding holes in transverse pipes are designed to self-align without requiring precise pre-drilling or complex alignment procedures, allowing workers to simply insert and secure the connections.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The vertical sliding door side frame pipes are designed with universal symmetrical features including identical slot positions, hole locations, and reinforcement structures on both left and right sides. This universality allows the same component design to be used for both sides, simplifying inventory and assembly procedures.

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

3Ease of operation

If traditional mounting structure is used, then the frame pipes can be securely fixed, but the mounting structure becomes complicated and installation is laborious

Engineering Contradiction:
ImproveinstallationVSAvoidmounting structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent divides the mounting structure into modular segments with standardized connection interfaces. The vertical and transverse pipes are designed with discrete, pre-positioned holes and slots that can be independently assembled, allowing for simplified step-by-step installation without complex integrated mounting structures.

Inventive Principle:
Principle #1Segmentation

4Shape

If screws are screwed from the inner side of vertical door frame side frames, then the frame pipes can be mounted, but the screws become exposed and affect appearance

Engineering Contradiction:
ImproveappearanceVSAvoidmounting operation
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The patent uses cover caps or end pieces that fit over the ends of the vertical sliding door side frame pipes, nesting the fastener heads within these cosmetic covers. This hides the screw heads and fastening elements from view while maintaining the structural integrity of the mounting connection.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present invention belongs to the field of outdoor articles, and particularly relates to an outdoor sliding door awning. The outdoor sliding door awning comprises a rack, wherein an awning top structure is installed at the top of the rack in a matched mode, a sliding door assembly is installed on at least one side of the rack in a matched mode, the sliding door assembly comprises a door frame structure and a sliding door embedded in the door frame structure in a sliding mode, the sliding door comprises a door plank and a side frame structure arranged on the periphery of the door plank in a surrounding mode, the side frame structure comprises an upper transverse sliding door side frame pipe, a lower transverse sliding door side frame pipe, a left vertical sliding door side frame pipe and a right vertical sliding door side frame pipe, the four side frame pipes are installed in a matched mode through first fasteners, non-metal pieces are installed in the upper ends and the lower ends of the vertical sliding door side frame pipes respectively, the non-metal pieces are provided with guiding holes, and the guiding holes are used for providing guidance for connection of the first fasteners between the transverse sliding door side frame pipes and the vertical sliding door side frame pipes. The beneficial effects of the present invention are as follows: the non-metal pieces are arranged in the two end openings of the vertical sliding door side frame pipes, the transverse sliding door side frame pipes are fixed through the guiding holes of the non-metal pieces by using self-tapping screws, and the effects of guiding, reinforcing, and reducing the sliding noises of the sliding door and the like can be achieved.
