Card Holder with Removable Insert for Hygienic Cupboard Labeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying and labeling contents in cupboards, especially in hospital settings, are inadequate due to the difficulty in replacing labels, accumulation of dirt, and challenges in maintaining hygiene, as traditional stickers are not easily removable and can leave residue.
Innovation Solution
A card holder with a plate-like body featuring side grooves and a downward folding wing that allows easy insertion and removal of cards, along with a secure fastening mechanism using an L-shaped groove and projecting rod, enabling easy assembly, disassembly, and thorough cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional stickers are used for labeling, then identification information is provided, but dirt accumulates at edges and replacement is difficult
Solution Approach 1:
The label system is segmented into a reusable card holder (body with rim) and replaceable cards. The card holder remains fixed on the cupboard front while only the cards need replacement, making information updates easy without removing the entire label assembly.
Solution Approach 2:
The information-bearing element (card) is extracted from the mounting structure (body). The card can be removed and replaced independently through the opening in the rim, allowing easy information updates without disturbing the fixed mounting portion.
2Loss of information

Solution Approach 1:
The label system is segmented into a reusable card holder (body with rim) and replaceable cards. The card holder remains fixed on the cupboard front while only the cards need replacement, making information updates easy without removing the entire label assembly.
Solution Approach 2:
The card is made as a thin, flexible element that can be easily inserted and removed through the opening in the rim. This thin-film approach eliminates the raised edges of traditional stickers that trap dirt, creating a flush surface that is easier to clean.
3Reliability
If fixed installation methods are used, then secure mounting is achieved, but hygiene cleaning is difficult
Solution Approach 1:
The information-bearing element (card) is extracted from the mounting structure (body). The card can be removed and replaced independently through the opening in the rim, allowing easy information updates without disturbing the fixed mounting portion.
Solution Approach 2:
