Solution Overview

Problem

Children often fail to recognize thirst and require incentives to hydrate adequately, and existing fluid containers lack designs that effectively engage and encourage them to drink enough water.

Innovation Solution

A container system with interchangeable sealing caps and caps that resemble attractive characters or toys, featuring coupling mechanisms, soft materials, and ergonomic designs to enhance engagement and encourage hydration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If children are provided with ordinary containers, then the container structure is simple, but children do not recognize thirst and do not drink enough fluids

Engineering Contradiction:
Improvefluid intakeVSAvoidcontainer structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The container system employs visually appealing designs, colors, and character-themed caps to attract children's attention and make the container more engaging, thereby encouraging increased fluid intake

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent introduces an intermediary incentive mechanism where children earn caps through good behavior, which they can then exchange for preferred caps. This mediator system bridges the gap between ordinary containers and children's motivation to drink

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If exchangeable sealing caps are used to incentivize children, then fluid intake increases, but the attachment mechanism becomes more complex

Engineering Contradiction:
Improvefluid intakeVSAvoidattachment mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The cap system is segmented into detachable sealing caps that can be independently exchanged. The cap separates from the container body through a coupling mechanism, allowing children to change caps without replacing the entire container, thus maintaining simplicity while enabling incentive programs

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling mechanism is designed with universal compatibility to work with multiple cap designs and container types. This multi-functional attachment system allows various sealing and decorative caps to be interchangeably attached using the same mechanism, reducing overall system complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If detachable head caps with attractive features are provided, then children's engagement increases, but manufacturing cost increases

Engineering Contradiction:
Improvechildren's engagementVSAvoidmanufacturing cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The sealing caps are designed as inexpensive, replaceable components that can be manufactured at low cost. Rather than making the entire container expensive and durable, the system uses affordable caps that can be easily replaced or exchanged, maintaining low manufacturing costs while providing attractive features for children

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

Systems for containing solid or liquid foodstuff are disclosed. An aspect of the system comprises a container configured to store the solid or liquid foodstuff. The container comprises an integral head coupler on its upper surface. The system also comprises a detachable head cap comprising an integral bottle coupler on its lower surface. The head coupler is configured to engage directly with the bottle coupler for mechanically connecting the detachable head cap to the container to seal the foodstuff thereof. The head coupler is configured to mechanically connect different head caps to the container. Optionally, the function of the detachable head cap is performed by two separate elements, a detachable head and a sealing cap.
