Container Lid With Hatch And Hygrometer For Humidity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lids for commercial containers, such as fiber drums, lack a means to monitor and control humidity levels and often require cumbersome lever locking mechanisms, making it difficult to access the contents without removing the entire lid.
Innovation Solution
A lid design featuring a hatch for easy access, a hygrometer for humidity monitoring, and a snap-fit locking mechanism, along with a dry-erase label surface, allowing users to adjust humidity using humidity packs stored in a pocket underneath the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lever locking mechanism is used to secure the lid, then the lid can be securely sealed, but it becomes cumbersome to access contents without removing the entire lid
Solution Approach 1:
The lid is divided into two functional parts: a main lid body that remains sealed on the container, and a removable hatch that provides access to contents. The latch mechanism secures the main lid body while the hatch can be independently opened, allowing users to access contents without breaking the main seal or removing the entire lid.
Solution Approach 2:
The access function is extracted from the main lid structure by adding a separate removable hatch. This hatch can be taken out or opened independently, separating the sealing function (main lid) from the access function (hatch), thereby solving the contradiction between secure sealing and easy access.
2Device complexity
If traditional lids are used without humidity monitoring, then the structure remains simple, but users cannot monitor or control humidity levels for agricultural products
Solution Approach 1:
The lid is designed with multiple functions integrated into a single device: sealing (latch mechanism), humidity monitoring (hygrometer), humidity control (humidity packs in receptacle), and labeling (dry-erase surface). This multi-functionality allows the lid to maintain agricultural product quality through humidity control while providing various user benefits.
Solution Approach 2:
A hygrometer is introduced as an intermediary device that monitors humidity levels and provides information to users. This allows users to indirectly observe and control humidity conditions without directly interacting with the stored agricultural products, enabling reliable humidity monitoring with minimal structural complexity.
3Reliability
If the entire lid must be removed to access contents, then the seal remains intact, but it is time-consuming and cumbersome
Solution Approach 1:
The lid structure is segmented into a permanent sealed portion (main lid body attached to container) and a temporary access portion (removable hatch). Users can open only the hatch to access contents, maintaining the seal integrity of the main lid while significantly reducing access time compared to removing the entire lid.
4Device complexity
If no labeling surface is provided, then the lid structure remains simple, but users cannot easily identify container contents
Solution Approach 1:
A specific local area on the lid surface is designated with different properties (dry-erase coating) to serve as a labeling zone. This localized modification provides content identification capability without requiring complex labeling mechanisms, maintaining overall structural simplicity while preventing information loss.

AI summary
A lid designed to allow a user to see and adjust the humidity levels of a container through the use of a hygrometer and pocket for humidity packs. The lid also allows this to be accomplished without removing the lid because a hatch gives the user access to the inside of the container and underside of the lid, where the pocket is located. Also, the hatch on the lid provides a more efficient and easier method of accessing the contents of a container because a user can simply open and close a hatch, instead of needing to unlock a lever locking latch to remove a lid.
