Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensionally adjustable hardware systems face challenges in stability, durability, convenience, and adjustability, particularly when dealing with large and heavy doors that require precise adjustments in multiple axes without compromising structural integrity or ease of use.
Innovation Solution
The system incorporates guide pins and threaded pins for z-direction adjustment, adjustment pins with oblique faces for x-direction adjustment, and sliding guides for y-direction displacement, allowing for precise and durable adjustments without releasing connections, along with conical surfaces and springs for enhanced interaction and low wear components like Teflon for reduced noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a hardware system is designed for high stability to handle large and heavy doors, then stability and strength are improved, but adjustability and ease of repositioning deteriorate
Solution Approach 1:
The hardware system is divided into multiple independent adjustment mechanisms for each axis (x, y, z), allowing stable mounting structure to be segmented into adjustable components. Each axis has dedicated adjustment devices (threaded pins for z-axis, sliding guides for y-axis, combination mechanisms for x-axis) that can be independently adjusted without affecting overall stability.
Solution Approach 2:
The system transitions from a static rigid structure to a dynamic adjustable structure through threaded pins that can be rotated to change positions, sliding guides that allow movement along tracks, and combination mechanisms that provide both locking and adjustment capabilities. This enables the hardware to adapt to different door configurations while maintaining stability during operation.
2Adaptability or versatility
If adjustment mechanisms are added to enable three-dimensional adjustability, then adaptability is improved, but device complexity and structural integrity deteriorate
Solution Approach 1:
The threaded pins serve multiple functions: they provide z-axis adjustment, act as mounting points, and can be used for securing the hardware body to the door frame. The sliding guides simultaneously provide y-axis adjustment and structural support. This multi-functionality reduces the need for separate components for each function, thereby reducing overall complexity despite the three-dimensional adjustability.
Solution Approach 2:
The hardware body acts as an intermediary component that connects the adjustable mechanisms (threaded pins, sliding guides) to the lever system. It provides a stable platform for adjustment while transmitting forces between the adjustment mechanisms and the door hardware, simplifying the overall structure by centralizing the adjustment functions in one component.
3Adaptability or versatility
If adjustment mechanisms are added to enable three-dimensional adjustability, then adaptability is improved, but manufacturing precision and assembly difficulty deteriorate
Solution Approach 1:
The threaded pins and sliding guides are designed to be self-aligning and self-adjusting. The threaded mechanism automatically maintains proper engagement as the hardware body is positioned, and the sliding guides provide inherent alignment along their tracks. This self-service capability reduces the need for high-precision manual assembly and minimizes the tolerance requirements for manufacturing.
Solution Approach 2:
The adjustment mechanisms replace complex mechanical linkages with simpler threaded and sliding movements. Instead of requiring precise mechanical couplings and linkages for three-dimensional adjustment, the system uses straightforward threaded pin rotation and sliding guide movement, which are easier to manufacture with standard tolerances and simpler to assemble.
4Shape
If the hardware system is made invisible when the door is closed, then aesthetic appearance is improved, but the accessibility for adjustment and maintenance deteriorates
Solution Approach 1:
The adjustment mechanisms (threaded pins, sliding guides) are nested within the hardware body and housing structure. When the door is closed, these components are concealed within the mortise and housing, creating an invisible appearance. When adjustment or maintenance is needed, the door is opened and the mechanisms become accessible from the edge of the door, allowing operation while maintaining aesthetic appearance during normal use.
