Solution Overview

Problem

Existing sliding carpentry devices face challenges in achieving optimal thermal insulation and ease of installation due to conflicting requirements between the need for insulation barriers and the freedom of movement of sliding elements, leading to increased complexity and cost.

Innovation Solution

A sliding carpentry device featuring a thermal insulation profile with elastic components that allows for movement during installation and returns to ensure insulation, covering the entire frame, including uprights and crosspieces, with a single profile that integrates into the U-shaped recess and is produced through coextrusion for simplicity and cost-effectiveness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If sealing barriers are installed in the U-shaped recess to improve thermal insulation, then thermal insulation performance is improved, but the freedom of movement of sliding elements deteriorates

Engineering Contradiction:
Improvethermal insulationVSAvoidfreedom of movement of sliding elements
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The sealing barrier is divided into multiple segments along its length, with gaps between segments that allow sliding elements to pass through during installation and operation. This segmentation maintains the thermal insulation function while eliminating interference with sliding movement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing barrier incorporates elastic elements that can deform dynamically. During installation, the elastic elements allow the barrier to flex and accommodate the passage of sliding elements. During normal operation, the elastic elements maintain contact to ensure thermal insulation while adapting to movement.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If multiple sealing solutions are implemented for different parts of the frame to optimize insulation, then thermal insulation is improved, but device complexity and installation time increase

Engineering Contradiction:
Improvethermal insulationVSAvoidcomplexity of sealing solutions
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

A single universal sealing barrier design is applied to all parts of the frame (uprights and crosspieces). This unified solution performs the same thermal insulation function across different frame locations, eliminating the need for multiple specialized sealing solutions and reducing overall device complexity.

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

Solution Approach 2:

The sealing barrier integrates multiple functions into a single component: thermal insulation, water infiltration prevention, and facilitation of sliding element installation. By combining these functions into one element rather than using separate components, the overall device complexity is reduced.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the U-shaped recess is left open to allow freedom of movement during installation, then ease of installation is improved, but thermal insulation performance deteriorates

Engineering Contradiction:
Improveease of installationVSAvoidthermal insulation
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The sealing barrier is pre-installed in the U-shaped recess before the sliding elements are placed. This preliminary installation ensures that the insulation barrier is already in position to provide thermal insulation, while its segmented or elastic design allows subsequent installation of sliding elements without compromising the barrier's effectiveness.

Inventive Principle:
Principle #10Preliminary action

AI summary

The invention relates to a sliding joinery device of the type in which the frame (100) is divided into two parts connected (300 and 400) by thermal break strips (510 and 520) and forming in its central interior a recess (600) with a U-shaped profile. This device is notable in that the frame (100) accommodates a thermal insulation profile (700) consisting of at least two interconnected parts (710 and 720). The first part (710) provides support and maintains the profile in the frame (100), while the second part (720) is substantially parallel to the bottom of the U and positioned as close as possible to the ends (210) of the sash profile (200) that enters the central recess (600). The connection between the two parts (710 and 720) is elastic, allowing movement of the second part. (720) part towards the first part (710) and its return to position.
