Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for moving movable furniture parts often experience undesirable triggering, leading to unintended opening or closing movements, which can result in inefficient energy usage and potential damage.
Innovation Solution
A device with an energy accumulator, ejector, and locking arrangement, featuring a delay element in the guide link to prevent unintentional triggering, allows controlled movement of furniture parts through a touch latch function, enabling controlled opening and closing with energy storage recharging during the closing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the device uses a power storage device and ejector for automatic opening movement, then the opening process is automated and energy-efficient, but the device becomes susceptible to unwanted triggering during closing movements
Solution Approach 1:
A delay element is introduced as an intermediary component between the release element and the power storage device. This delay element temporarily decouples the triggering mechanism from the power storage device during closing movements, preventing unwanted activation while allowing intentional triggering when needed.
Solution Approach 2:
The delay element is pre-positioned in the triggering path before the release element reaches the power storage device. This preliminary positioning ensures that any movement during the closing phase is absorbed or delayed before it can trigger the opening mechanism, providing a buffer against unintended activation.
2Speed
If the release element is directly connected to the power storage device, then the response time is fast, but friction and wear increase
Solution Approach 1:
The delay element serves as a mediator that reduces direct frictional contact between the release element and the power storage device. By introducing this intermediate component, the system maintains functional connectivity while minimizing wear and energy loss through reduced direct contact friction.
