Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Concealed hinges on the market are bulky, have a large number of parts, lack control over the closing mechanism, and pose safety concerns due to the risk of doors impacting frames when pushed by users.
Innovation Solution
A hinge design with a concealed fixed hinge body embedded in a wall or door, featuring a tubular member and a connection assembly that allows for hydraulic damping and automatic closing, reducing the number of parts and enhancing safety by controlling the door's closing position and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If concealed hinges are designed to be compact with fewer parts, then device complexity is reduced and ease of manufacture is improved, but safety is worsened due to the risk of doors impacting frames when pushed by users
Solution Approach 1:
The hinge applies preliminary anti-action by incorporating a door stop mechanism that prevents the door from impacting the frame before the harmful impact can occur. The door stop is integrated into the hinge structure and activates when the door approaches the frame, creating a counter-force that stops the door's movement and prevents damage.
Solution Approach 2:
The invention merges multiple functions into a single integrated hinge structure. The door stop, hinge mechanism, and mounting components are combined into one unified assembly, reducing the total number of separate parts while maintaining safety functionality. This consolidation eliminates the need for separate door stop components that would increase complexity.
2Reliability
If concealed hinges include control mechanisms for closing elements, then reliability and safety are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The hinge employs self-service principles through its automatic door stop mechanism that operates without external control systems. The door stop activates automatically when the door approaches the frame, using the door's own momentum and the hinge's integrated structure to provide control. This eliminates the need for separate motors, sensors, or control electronics that would increase complexity.
3Strength
If concealed hinges are designed to support very heavy doors, then strength and load-bearing capacity are improved, but device complexity and dimensions increase
Solution Approach 1:
The hinge utilizes composite construction principles by combining different materials with complementary properties. The hinge body incorporates high-strength metals for load-bearing components while using engineered composites or reinforced polymers for structural elements. This material strategy enables the hinge to support heavy doors without requiring an excessive number of parts or increasing overall dimensions significantly.

AI summary
A concealed hinge for the rotatable movement of a door fixed to a door frame. The hinge includes: a fixed hinge body anchorable to the frame; a movable hinge body anchorable to the door; a connecting assembly for mutual connection of the fixed hinge body and movable hinge body so that the latter rotates with respect to the former about a first longitudinal axis between an open position and closed position. The fixed (or movable) hinge body includes a first (or second) box-shaped element concealedly insertable within the door (or frame). The first (or second) box-shaped element defines a second axis parallel to the first axis. The connecting assembly protrudes from the first box-shaped element in the open position of the movable element, the first box-shaped element being susceptible to internally contain the connecting assembly in the closed position of the movable element.
