Box Washer Door Lock Segmentation for Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art crate washers have door locks that are not robust and prone to wear due to fine mechanics, leading to a risk of unintentional opening during washing or cleaning processes.
Innovation Solution
A door lock design featuring a lever element mounted parallel to the pivot axis, which pivots to switch between open and closed modes, using a fixing element with an engagement area for latching, eliminating the need for additional complex mechanical components, thereby enhancing operational stability and simplicity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional door locks with fine mechanics are used, then the door can be locked, but the door lock shows signs of wear after frequent use and is prone to unintentional opening
Solution Approach 1:
The door lock is divided into two separate elements: a fixing element attached to the housing and a lever element attached to the door. This segmentation simplifies each component's structure, eliminating complex internal mechanics while maintaining reliable locking function through their interaction.
Solution Approach 2:
Instead of using a complex locking mechanism that actively prevents opening, the invention uses a simple lever element that passively latches with the fixing element. The locking action is inverted from an active complex mechanism to a passive geometric interlocking system.
2Ease of manufacture
If simple door locks are used, then the design is cost-effective, but the door lock is not robust and shows wear after frequent use
Solution Approach 1:
By segmenting the door lock into separate fixing and lever elements, each component can be manufactured simply and economically while maintaining robustness. The segmentation allows for easier manufacturing without compromising operational stability.
Solution Approach 2:
The lever element automatically latches with the fixing element through its pivoting motion, eliminating the need for complex spring mechanisms or additional locking components. This self-latching mechanism reduces manufacturing complexity while ensuring reliable operation.
