Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multipoint locks with peripheral assemblies generate bothersome noise due to metallic components striking each other during operation, particularly in multi-unit buildings where noise can disturb adjacent units.
Innovation Solution
A soundproof lock design featuring a box-like body with a deformable material element and rocker arm mechanism that dampens the impact between the sliding latch and spring latch, minimizing noise through controlled translations and rotations, and using deformable materials to absorb shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional multipoint locks with peripheral assemblies are used, then high security against forcing is achieved, but noise is generated due to metallic components striking each other during operation
Solution Approach 1:
A deformable material element is introduced as an intermediary between the sliding latch and the box-like body. This element absorbs impacts and prevents direct metal-to-metal contact, thereby eliminating noise while preserving the locking function and security properties of the traditional multipoint lock system
Solution Approach 2:
The impact forces that previously caused harmful noise are converted into beneficial deformation of the deformable material element. The material absorbs the kinetic energy of the sliding latch during operation, transforming the harmful impact into a useful damping effect that reduces noise while maintaining structural integrity
2Strength
If metallic components are used in the lock mechanism, then structural strength and security are maintained, but acoustic emissions increase due to component impact
Solution Approach 1:
The lock mechanism transitions from purely metallic components to a composite structure incorporating a deformable material element. This composite approach maintains the structural strength provided by metallic components while adding noise-dampening properties through the deformable material, effectively resolving the contradiction between strength and acoustic emissions

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The soundproof lock provides stable locking with negligible acoustic impact, high security against forced entry, and is cost-effective and easy to implement, reducing noise disturbances in residential and commercial settings.
Implementation Method 1
a deformable material element (18) for dampening the impact between the sliding latch (4) and spring latch (19)
Implementation Method 2
an element made of deformable material 18 is interposed between the wall 16 of the box-like body 2, on which the sliding latch 4 abuts with a face 17 thereof when it is in the configuration of total extraction, and that face 17, for damping the impact between those components during the extraction of the sliding latch 4

AI summary
A soundproof lock (1) that comprises a box-like body (2) for accommodating at least one actuation element (3) for at least one sliding latch (4) which is pivoted on an inner wall of the box-like body (2) and can move between an extracted configuration and a retracted configuration with respect to the box-like body (2) as a result of corresponding translations of the element (3) along a path inside the box-like body (2) which is defined by at least one first slot (5) thereof within which at least one first plug (6) is engaged which is integral with an inner wall of the box-like body (2). The actuation element (3) comprises at least one contoured second slot (7) for the slideable accommodation of a peg (8) for pivoting the at least one sliding latch (4); the sliding latch (4), at the peg (8), is provided with at least one eccentric projection (9) which can be accommodated, in the configuration of total extraction of the sliding latch (4), in a respective recess (10) of the second slot (7). At least one rocker arm (11), which is pivoted on an inner wall of the box-like body (2), comprises an end tab (12) which is contoured and adapted to abut on a corner (13) of the edge of the sliding latch (4); the abutment of the tab (12) on the corner (13) blocks the rotation of the sliding latch (4). A seat (14) of the lateral edge of the element (3) is aligned with a protruding tooth (15) of the at least one rocker arm (11); a translation of the element (3) causes the abutment of the tooth (15) against the seat (14), with forcing of the rotation of the rocker arm (1 1) and distancing of the end tab (12) from the corner (13) of the sliding latch (4). An element made of deformable material (18) is interposed between the wall (16) of the box-like body (2), on which the sliding latch (4) abuts with a face (17) thereof in the configuration of total extraction, and such face (17), for damping the impact between such components during the extraction of the sliding latch (4).
