Openwork Pillowcase Insertion Device to Minimize Friction and Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for changing pillowcases are inefficient and cumbersome, lacking a practical solution for easily inserting and removing pillows without causing friction or damage.
Innovation Solution
A device comprising an openwork structure with hinges and a handle that compresses and minimizes friction, allowing the pillow to be inserted into the pillowcase and then easily removed by opening the structure, utilizing spring-loaded hinges and a trap jaw mechanism to facilitate smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a pillow is directly inserted into a pillowcase, then the process is simple, but friction and damage occur during insertion and removal
Solution Approach 1:
The patent introduces an intermediate device consisting of a pillow holder and pillowcase holder that mediate between the pillow and the pillowcase. The pillow holder compresses the pillow while the pillowcase holder receives it, reducing direct friction and damage during insertion and removal operations.
Solution Approach 2:
The device is divided into separate functional components: a pillow holder for compressing and holding the pillow, a pillowcase holder for receiving and manipulating the pillowcase, and a connecting mechanism. This segmentation allows each component to perform its specific function efficiently while reducing overall friction and damage.
2Object-affected harmful factors
If a device is used to insert and remove pillows, then friction and damage are reduced, but the device complexity increases
Solution Approach 1:
The pillow holder incorporates spring-loaded clamps that automatically clamp onto the pillow when inserted and release when the pillow is removed. The connecting mechanism between the pillow holder and pillowcase holder automatically engages and disengages, reducing the manual effort required and simplifying operation while maintaining protection against friction and damage.
3Object-affected harmful factors
If the openwork structure is used to contain and insert the pillow, then friction is minimized, but the device complexity increases
Solution Approach 1:
The pillow holder and pillowcase holder utilize flexible, openwork structures that can deform and adapt to the pillow's shape. This flexibility minimizes friction during insertion and removal while the modular design of the openwork structure keeps the overall device complexity manageable through standardized components.
