Drawer Catch Fitting for Synchronous Unlocking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking systems for movable furniture parts often fail to ensure synchronous unlocking of locking fittings, leading to uneven unlocking and potential damage, especially in wider drawers where manual unlocking can result in imbalance and high forces on components.
Innovation Solution
A locking system with triggers for each locking fitting that can be simultaneously actuated using a control, coupled with sensors and various drives (like lifting magnets) to ensure synchronized unlocking and parallel guidance of movable furniture parts, preventing damage from uneven forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual unlocking mechanism is used, then device complexity is reduced, but reliability deteriorates due to asynchronous unlocking of locking fittings
Solution Approach 1:
The control system is segmented into distributed control units, each associated with individual locking fittings, rather than a centralized complex system. This allows independent control of each locking fitting while maintaining synchronization through coordinated actuation signals.
Solution Approach 2:
Multiple control functions are merged into integrated control units that can simultaneously manage multiple locking fittings. The control system combines sensor inputs, signal processing, and actuation control in unified modules, reducing overall system complexity while ensuring synchronous operation.
2Reliability
If synchronous unlocking control is implemented, then reliability is improved, but device complexity increases due to additional sensors and drives
Solution Approach 1:
The control units are designed with multi-functionality, serving both as sensors for detecting drawer position and as actuators for unlocking locking fittings. This universal design reduces the need for separate dedicated components, thereby reducing overall system complexity while maintaining reliable parallel guidance.
Solution Approach 2:
The locking fittings are equipped with self-contained control units that autonomously manage their own unlocking operations. Each control unit independently monitors its associated locking fitting and actuates it when appropriate, reducing the need for complex external control mechanisms while ensuring synchronized operation across all fittings.
3Stability of the object's composition
If multiple locking fittings are used for wide drawers, then stability is improved, but ease of operation deteriorates due to difficulty in achieving synchronous unlocking
Solution Approach 1:
The control system incorporates feedback mechanisms that monitor the status of each locking fitting and adjust actuation signals accordingly. Sensors detect the position and state of drawer and locking fittings, providing real-time feedback to control units, which then coordinate unlocking actions to ensure smooth, synchronous operation that is easy for users to operate while maintaining stable drawer support.
