Angled trailing side for a trigger head of a slide assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide assemblies in dishwashing appliances experience a decrease in functionality due to skipping failure modes when slammed shut, leading to locking and preventing extension, necessitating a reset mechanism.
Innovation Solution
A slide assembly with a soft close mechanism and a trigger assembly, featuring a trigger head with angled trailing sides, is designed to dampen movement and facilitate resetting after a skipping failure mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the slide assembly includes a soft close mechanism to dampen movement, then the movement control is improved, but the complexity of the device increases
Solution Approach 1:
The trigger head is divided into distinct functional segments: a base portion that engages with the saddle and an angled trailing side portion that provides the reset function. This segmentation allows the damping function and reset function to be implemented as separate geometric features within a single component, improving reliability without proportionally increasing overall device complexity.
Solution Approach 2:
The angled trailing side of the trigger head acts as an intermediary element between the trigger assembly and the saddle. When the trigger head contacts the saddle during forceful closure, the angled surface provides a controlled interaction point that enables automatic resetting without requiring additional intermediary components or complex mechanisms.
2Adaptability or versatility
If the trigger head has a complex base and arm configuration to engage with the saddle, then the functionality is improved, but the ease of manufacture decreases
Solution Approach 1:
The base portion and arm portion of the trigger head are merged into a single integrated component with a unified structure. The base includes both the engagement surface for the saddle and the angled trailing side for resetting, eliminating the need for separate parts assembly and simplifying manufacturing while maintaining the required engagement functionality.
Solution Approach 2:
The trigger head is designed as a multi-functional component that simultaneously provides: (1) engagement with the saddle through the base portion, (2) damping of movement through the controlled interaction with the saddle, and (3) automatic resetting through the angled trailing side. This multi-functionality reduces the total number of components needed while achieving complex operational requirements.
