Angled Wall Door Pivot System with Air Cushioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems for non-zero angle configurations in living rooms are aesthetically unpleasing when open, produce noise and shock when transitioning between positions, and are designed for parallel walls only.
Innovation Solution
A door mounting system with a pivot axis in a common zone between two contiguous walls forming a non-zero angle, featuring a through opening and housing with a complementary shape, allowing the door to pivot smoothly between closed and open positions without projecting unsightly when open, and incorporating locking-unlocking means for secure alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the door is mounted on protruding hinges, then the door can pivot between positions, but it folds back against the wall when open which is aesthetically unpleasing
Solution Approach 1:
The door is nested within a recess formed by two contiguous walls at an angle to each other. When the door is in the open position, it is contained within this recess space rather than protruding outward, achieving a clean aesthetic appearance while maintaining full pivoting functionality around a hidden pivot axis
Solution Approach 2:
The solution moves from a single-wall mounting approach to a multi-dimensional configuration using two contiguous walls forming a recess. This creates a three-dimensional space that accommodates the door in both open and closed positions without protruding hinges visible, resolving the aesthetic conflict
2Ease of operation
If the door pivots between open and closed positions, then it provides functional access, but noise and shock occur during transition
Solution Approach 1:
A damping element is pre-installed on the door to cushion the impact during closing. This element contacts the rear face of the door near the pivot axis to absorb shock and reduce noise before the door fully closes, preventing the harmful slamming effect
3Shape
If the door is integrated into a through opening between angled walls, then aesthetic alignment is achieved, but the pivot mechanism becomes complex
Solution Approach 1:
The pivot axis is merged with the common zone between the two contiguous walls, eliminating the need for separate protruding hinge assemblies. The pivot mechanism becomes an integrated part of the wall structure itself, maintaining aesthetic alignment while reducing mechanical complexity
Applied Scientific Principles
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 system eliminates noise and shock during position transitions, maintains aesthetic alignment with walls in both positions, and ensures smooth operation by utilizing a concave shape in the housing to accommodate the door's pivoting, creating a cushioning effect with air to dampen noise.

AI summary
Disclosed is a system for constructing a habitable room or the like including at least one door, walls, and door mount to pivot relative to the two walls about an axis in such a manner as to be suitable for occupying at least two positions, namely a “closed” position in which the door is contained in the plane of the first wall, and an “open” position in which the door is not. The system includes a through opening and a setback each presenting a shape substantially complementary to the door and made respectively in the first and second walls, and together having a common zone, with the axis in the zone, and arranged in such a manner that, on pivoting about the axis, the door in its first position it is integrated in the opening, and when it is in its second position, it is contained in the setback.
