Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking fittings for narrow frames are not compact enough while maintaining structural simplicity and safety, making them inefficient for narrow furniture applications.
Innovation Solution
A compact locking device design featuring a one-piece or multi-part base body with a release lever, catch lever, and energy accumulator, where the catch lever and release lever move in parallel planes, and the energy accumulator is tensioned to securely pull a panel towards the frame, with a spiral spring arrangement providing the necessary spring force for actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a locking device is designed for narrow frames, then the compactness is improved, but the structural simplicity deteriorates
Solution Approach 1:
The patent combines multiple functional elements (base body, catch lever, release lever, and energy accumulator) into a integrated locking device assembly. The energy accumulator is positioned within the base body structure, and the levers are arranged in parallel planes to share common mounting points, merging separate components into a compact unified structure that reduces overall volume while maintaining functional simplicity
Solution Approach 2:
The catch lever and release lever are arranged in parallel planes and aligned in sections when viewed perpendicular to these planes. This three-dimensional spatial arrangement allows the levers to move without interfering with each other, achieving compactness in narrow frame applications while maintaining clear functional separation and structural simplicity through optimized spatial configuration
2Force
If the energy accumulator is positioned to pull the panel securely, then the holding force is improved, but the device complexity increases
Solution Approach 1:
The energy accumulator is configured to automatically pull the connecting fitting toward the frame when the release lever is not engaged. The spring mechanism self-actuates to secure the panel without requiring additional actuators or complex control systems, achieving strong holding force while maintaining device simplicity through self-service operation
Solution Approach 2:
The energy accumulator is integrated within the base body structure with its ends passing through holes in the base body. This merging of the force-generating component with the structural base eliminates the need for separate mounting brackets or external positioning mechanisms, achieving secure holding force while reducing overall device complexity
3Ease of operation
If the catch lever and release lever are arranged in parallel planes, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The catch lever and release lever are positioned in parallel planes with their movement paths aligned in sections when viewed perpendicular to these planes. This spatial arrangement allows both levers to be operated independently without mechanical interference, improving ease of operation while the levers share common mounting points on the base body, thereby limiting the increase in device 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 solution achieves a compact and securely operating locking fitting that is suitable for narrow frames, ensuring the panel is securely held and easily released, addressing the need for a more efficient and space-saving design.
Implementation Method 1
The energy storage can consist of one or more spring elements and possibly connecting or deflection elements, bolts or levers.
Implementation Method 2
The energy accumulator is tensioned to securely pull a panel towards the frame, with a spiral spring arrangement providing the necessary spring force for actuation.
Implementation Method 3
the energy storage is designed as a spiral spring arrangement, since such a spiral spring arrangement particularly well provides the necessary spring force for actuation
