Movement Device for Mobile Element with Simultaneous Linear Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement devices for mobile elements like doors and windows are limited by the need for reduced thickness due to encumbrance issues during translation, require two separate maneuvers, and are prone to jamming due to dirt, dust, or wear, leading to operational difficulties.
Innovation Solution
A movement device with a longitudinal translation guide and transversal moving means that allows for simultaneous linear movement of both rims into the frame opening, eliminating the need for rotational movement and accommodating thicker mobile elements, while incorporating features like a lateral glass portion for light transparency and a deviator element to manage condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the mobile element has greater thickness, then the mobile element can provide better structural strength and insulation, but the mobile element cannot completely enter the frame opening due to excessive encumbrance during translation in the curvilinear section
Solution Approach 1:
The patent inverts the traditional movement sequence by eliminating the curvilinear translation section and requiring rotational movement first. The mobile element rotates about its axis to engage the frame opening, then translates linearly. This inversion allows thicker elements to enter the frame opening without encumbrance issues, as the rotation occurs outside the frame plane where thickness is not a constraint.
2Reliability
If two separate maneuvers (translation then rotation) are required, then the movement device can guide the mobile element into the frame opening, but the operation becomes complex and requires exact positioning which is difficult to maintain over time due to wear and contamination
Solution Approach 1:
The patent merges the translation and rotation operations into a single integrated maneuver. The mobile element rotates about its axis while simultaneously translating linearly into the frame opening, eliminating the need for separate maneuvers and exact positioning. This combined operation reduces complexity and improves reliability by eliminating the sequential dependency and positioning precision requirements.
3Reliability
If curvilinear translation guide is used, then the mobile element can be guided into the frame opening, but the translation guide jams or requires considerable manual effort after some time due to dirt, dust, rust, or wear
Solution Approach 1:
The patent inverts the movement sequence to perform rotation first, then translation. By eliminating the curvilinear translation section that is prone to contamination, the design reduces the surface area and complexity of the translation guide. The linear translation section is shorter and less exposed to environmental contaminants, reducing jamming and wear issues.

AI summary
The present invention is related to a movement device (1) of a mobile element (4) in relation to a fixed frame (2), which develops in a frame plane and which defines a frame opening (3) which can be engaged by the mobile element (4). The device comprises a longitudinal translation guide (5, 5') which can be joined to the fixed frame (2) and suitable for allowing the translation of the mobile element (4) along a primary translation axis between a configuration of at least partial superimposition of the mobile element (4) with the frame opening, and at least one configuration of non-alignment with the opening. The device further comprises transversal moving means (18, 19, 6', 6'', 22, 23, 24), operatively connected to the mobile element so as to allow, when the latter is in the configuration of superimposition, its movement along a secondary movement axis, incident to the primary translation axis, between the configuration of superimposition and a closing configuration, wherein the mobile element is engaged in the frame opening. Furthermore, the secondary trajectory Y is substantially linear or rectilinear at least in its terminal section towards the frame opening.
