Solution Overview

Problem

Existing window and door frame systems require substantial time for assembly due to the need to cut and drill transmission rods to match varying dimensions, and there is a risk of waste blocking the sliding mechanism during this process.

Innovation Solution

A transmission rod with a central part forming a closed longitudinal channel, allowing waste to be retained and preventing blockage, combined with percussion fixing means for quick attachment of accessories, enabling efficient assembly and maintaining rod functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If percussion fastening means is used to quickly attach accessory to transmission rod, then assembly time is reduced, but debris is generated during drilling that may block the sliding motion

Engineering Contradiction:
Improveassembly timeVSAvoidsliding motion
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent converts the harmful debris generated during percussion drilling into a contained element by designing a closed longitudinal channel that captures and retains the debris within its structure, preventing it from blocking the sliding motion while maintaining the efficiency of percussion fastening

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The closed longitudinal channel acts as an intermediary structure between the percussion fastening process and the sliding mechanism, intercepting the debris before it can interfere with the sliding motion of the transmission rod in the guide groove

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If transmission rod dimensions are customized to fit different opening sizes, then adaptability is improved, but assembly time increases due to cutting and drilling requirements

Engineering Contradiction:
Improvedimensional adaptabilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The transmission rod is pre-designed with a closed longitudinal channel structure that facilitates quick percussion fastening of accessories at any position along its length, eliminating the need for time-consuming cutting and drilling operations during assembly while maintaining dimensional adaptability

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to an opening (1) or fixed profile on which at least one longitudinal guide groove (3) is provided, said profile (1) comprising: a transmission rod (5) intended to be housed inside said guide groove (3) in a movable form in translation and comprising a central part (25) extending longitudinally over the entire length of said transmission rod (5); an accessory (7) adapted to engage with said transmission rod (5) for the actuation of said transmission rod (5);and a percussion fastening means (10) for fixing the accessory (7) onto said transmission rod (5), said central part (25) defining: an upper wall (27), intended to be pierced by the percussion means, and on either side of the upper wall, two lateral walls (33, 33') forming with the upper wall (27) a channel capable of receiving at least a part of the fastening means and extending longitudinally over the entire length of said central part (25).
