Washing Machine Door Lock Housing for Transport Impact Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drum type washing machines are prone to damage during transportation due to impact, as existing locking devices fail to securely maintain the door in a closed state, allowing water to spill and causing structural instability.
Innovation Solution
The design incorporates a locking device with a first and second through hole, supported by a first and second support, respectively, which are in a plane contact state, dispersing external impact and preventing damage by stabilizing the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device is provided to maintain the door closed state, then the door can be securely locked, but the locking device becomes vulnerable to impact damage during transportation
Solution Approach 1:
The patent applies beforehand cushioning by providing support structures (first support and second support) that extend into through holes of the locking device and housing respectively. These supports create a cushioning effect that absorbs and disperses impact forces before they can damage the locking mechanism, thereby protecting the reliable door locking function while mitigating transportation impact risks
2Strength
If the locking device is made robust to resist impact, then damage during transportation is prevented, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the impact protection function into separate support components (first support extending from the locking device, second support extending from the housing). This segmentation allows each support to be relatively simple in structure while collectively providing robust impact resistance, avoiding the need for a single complex reinforced locking device structure
3Reliability
If the door is kept closed during washing, then water containment is achieved, but the locking mechanism must withstand external impact forces
Solution Approach 1:
The patent applies the intermediary principle by introducing support structures as mediator elements between the locking device and the external environment. The first support extending into the first through hole and the second support extending into the second through hole act as intermediaries that absorb and disperses impact forces, protecting the locking mechanism that maintains water containment while withstanding external impact forces

AI summary
A drum type washing machine including a housing having an introduction port, a door to open and close the introduction port, a locking member provided at the door, a locking device provided at the housing to lock the locking member. The locking device has a first through hole and a first support extending from the perimeter of the first through hole. The housing has a second support extending from the perimeter of a second through hole, through which the first support is inserted, to support the outside of the first support in a plane contact state. The first support is prevented from being damaged due to impact during transportation.
