Solution Overview

Problem

The existing methods for manufacturing and installing gate-type exterior doors face challenges in adapting the door length to match the distance between fixed points, leading to increased manufacturing time and cost due to the need for custom cutting and adjustments during installation, which can result in errors and imperfect closure.

Innovation Solution

The method involves designing each door into two sections, with the first section having fixed spacers at the ends to create an internal space and the second section sliding within, allowing telescopic adjustment to match the frame dimensions, which can be fixed in place once the desired length is achieved, using standard sections that can be easily assembled and adjusted on-site.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If custom cutting and adjustment is performed during installation to adapt door length to frame dimensions, then the door can be precisely fitted to the opening, but manufacturing time increases and cost becomes prohibitive

Engineering Contradiction:
Improvedoor length adaptation precisionVSAvoidmanufacturing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The door is divided into multiple modular sections that can be independently manufactured to standard lengths and then assembled together during installation. This segmentation allows the door to be adapted to various opening lengths without requiring custom cutting of each individual door, thus reducing manufacturing time while maintaining fitting precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The door assembly incorporates telescopic sections with sliding mechanisms that allow the door length to be dynamically adjusted during installation to match the specific opening dimensions. This dynamic adjustment capability eliminates the need for permanent custom cutting while achieving precise fit.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If custom cutting is performed on-site during installation to adjust door length, then the door can be adapted to the specific opening, but errors occur leading to approximate closing

Engineering Contradiction:
Improvedoor length adaptabilityVSAvoidclosing precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The door sections are pre-manufactured with standardized dimensions and precision-engineered connection interfaces. The telescopic mechanism includes pre-configured stopping points and alignment features that guide the assembly to the correct length, preventing installation errors and ensuring precise closing without requiring complex on-site measurements and cutting.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If standard door lengths are used without modification, then manufacturing time and cost are reduced, but the fixed points must be modified to suit the door length

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidframe modification complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The door is constructed from multiple standardized sections that can be combined in different configurations to match various opening lengths. This allows standard door components to be used without modifying the fixed points or frame, as the modular door assembly can be adjusted to fit the existing frame dimensions.

Inventive Principle:
Principle #1Segmentation

4Length of stationary object

If long door lengths are used to span large distances between fixed points, then the opening can be closed, but excessive space is required for the door to move during opening and closing operations

Engineering Contradiction:
Improvedoor lengthVSAvoidmovement space requirement
Core Design Contradiction:
Length of stationary objectVSArea of stationary object

Solution Approach 1:

The door incorporates telescopic sections where one section can slide within another, allowing the door to compact to a shorter length when not in full deployment. This nesting mechanism reduces the clearance space required for door movement while maintaining the ability to span large openings when fully extended, as the door can be retracted into a more compact configuration during opening and closing operations.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

The present invention is a method for manufacturing and installing a gate device (1), consisting of at least one door, characterized in that: each door is designed in a first (6) and a second (7) section, with an internal space (12) in its thickness, the thickness of the second section (7) corresponding to said space (12); said door is arranged telescopically by sliding said second section (7) into said first section (6); the lateral end of said first section (6) is articulated and fixed to a fixed point of a frame (3); the length of said door is adjusted, relative to another fixed point of said frame or another door, by sliding translational movement of said second section (7) within said space (12) and along said first section (7); and the second section (7) is fixed relative to the first (6).
