Liquid Cartridge Container Ribs for Drop Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cartridge containers fail to adequately protect liquid cartridges from damage due to impact during transportation, particularly those with large ink volumes or integrated liquid discharge heads, which are prone to deformation and damage from shock.
Innovation Solution
A container design featuring inwardly protruding ribs that extend parallel to the bottom and inclined relative to the side walls, dispersing impact forces and absorbing shocks to prevent direct contact with the liquid discharge head, using recycled plastics for the container and cover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If columnar ribs are used to prevent container deformation, then the container is protected from external environmental changes, but the liquid cartridge is vulnerable to impact damage from drop shocks
Solution Approach 1:
The ribs are divided into multiple segments with different orientations: first ribs extending from bottom to opening and second ribs extending from side walls. This segmentation allows each rib type to handle specific impact directions, distributing the protective function across multiple structural elements rather than relying on a single rib configuration.
Solution Approach 2:
Different regions of the container have different rib configurations tailored to local protection needs. The first ribs provide protection along the vertical axis (bottom to opening), while second ribs provide lateral protection from side walls. This localized structural optimization ensures impact protection is directed where needed most without unnecessary material usage.
2Reliability
If the container structure is made more complex to absorb impact, then the liquid cartridge is better protected, but the manufacturing cost and structural complexity increase
Solution Approach 1:
The first and second ribs are integrated into a single container body structure rather than being separate components. This merging of protective elements into one unified structure provides comprehensive impact protection while avoiding the complexity of assembling multiple separate protective components.
Solution Approach 2:
The ribs serve multiple functions simultaneously: they prevent container deformation under external pressure, absorb impact forces during drop shocks, and provide structural support for the container shape. This multi-functionality reduces the need for additional specialized protective components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The container effectively absorbs and disperses impact forces, reducing the risk of damage to the liquid discharge head and substrate, while being cost-effective through the use of recycled materials.
Implementation Method 1
a plurality of ribs protrudes from an inner surface of at least one of the at least four side walls of the storage unit toward an inside of the storage unit and extends from the bottom toward the opening
