Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door release apparatuses for vehicles are costly and time-consuming to produce, require skilled labor, and involve polluting welding processes, while also being complex and prone to defects.
Innovation Solution
A door release apparatus with a button made from a single, cold-deformed metal plate laminar element that is articulated to a base without welding, using rivets for reinforcement and simplified production steps to reduce costs and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the button is made by welding multiple intermediate components, then the mechanical strength and structural integrity are ensured, but the production cost increases, production time lengthens, and skilled labor is required
Solution Approach 1:
The invention merges multiple separate components (button body, supporting arms, reinforcement elements) into a single monolithic piece made from one metal plate. This eliminates the need for welding or other joining operations, thereby reducing production cost and complexity while maintaining structural integrity through the unified design
2Stability of the object's composition
If the button is made by welding multiple intermediate components, then the structural integrity is ensured, but the production time increases due to multiple work steps
Solution Approach 1:
The invention combines multiple manufacturing steps (cutting, bending, shaping, assembling) into a single stamping or forming operation that produces the complete button in one piece. This dramatically reduces production time while ensuring structural integrity through the monolithic construction
3Strength
If the button is made by welding multiple intermediate components, then the mechanical strength is ensured, but skilled personnel are required for execution and inspection
Solution Approach 1:
The invention consolidates the button design into a single-piece construction that can be manufactured using standard stamping or forming equipment operated by unskilled personnel. The monolithic design eliminates welding operations and the associated skill requirements for both manufacturing and quality inspection
4Stability of the object's composition
If welding is used to assemble the button components, then the structural integrity is ensured, but polluting materials and cleaning processes are required
Solution Approach 1:
The invention creates a single-piece button through stamping or forming operations that do not require welding, thereby eliminating the need for chemical cleaning agents and waste disposal processes. The monolithic construction achieves structural integrity without introducing harmful substances into the manufacturing environment
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

AI summary
A release apparatus for doors of vehicles, such as vans, trucks, heavy goods vehicles, articulated trucks, trailers and the like, comprising a base (2), which can be anchored stably to the door, and a handle assembly (3), which can be anchored to at least one rod (A) that can be coupled rotatably to the door and supports respective means for anchoring to the frame of the vehicle. The handle assembly (3) can rotate with respect to the base (2) between at least one locking configuration, in which the anchoring means can engage even indirectly the frame of the vehicle, and at least one release configuration, in which the anchoring means are in any case disengaged from the frame of the vehicle, in order to allow the rotation of the door; a locking button (4) is coupled rotatably to the base (2) and is reversibly movable between at least one first angular position, in which it is arranged even indirectly so as to interfere with the motion of the handle assembly (3), and at least one second angular position, in which it 'is spaced from the handle assembly (3), in order to allow its movement; the button (4) comprises a laminar element (5), which is provided in one piece and has a substantially flat central portion (5a), which is interposed between respective opposite end flaps (5b), which are bent and are articulated to the base (2).
