Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The excessive waste and environmental pollution caused by non-degradable packaging materials for pasty or solid household chemicals, as these materials are typically discarded after use and not reusable.
Innovation Solution
A packaging device with a lifting mechanism that allows for the reuse of the packaging by detachably connecting a refill device, where the lifting mechanism moves the refill device's case bottom to facilitate the ejection and retraction of the chemicals, and the refill device is made of degradable materials for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packaging materials are used for pasty or solid household chemicals, then the packaging provides adequate protection and containment, but the packaging cannot be reused and causes environmental pollution after use
Solution Approach 1:
The packaging system is divided into two separable parts: a reusable outer packaging device (case body and case cap) and a disposable inner refill device. This segmentation allows the outer packaging to be reused while the inner refill is discarded after use, resolving the contradiction between providing reliable packaging protection and minimizing packaging waste.
Solution Approach 2:
The invention implements a system where the refill device is discarded after use but the outer packaging device is recovered and reused. The lifting mechanism facilitates this by enabling easy removal of the used refill device from the case body, allowing consumers to insert a new refill into the same case, thus recovering and reusing the outer packaging.
2Loss of substance
If the packaging device is designed to be reusable, then packaging material waste is reduced, but the device structure becomes more complex requiring additional mechanisms
Solution Approach 1:
The lifting mechanism incorporates a threaded rod that converts rotational motion into linear motion, allowing the lifting platform to dynamically adjust its position vertically. This dynamic mechanism enables the lifting platform to rise and fall smoothly, providing an elegant solution for ejecting the refill device without requiring complex mechanical linkages or multiple moving parts.
Solution Approach 2:
The invention replaces complex mechanical linkage systems with a simpler threaded rod mechanism. Instead of using cams, levers, or multiple gears to achieve the lifting and ejecting function, the patent uses a single threaded rod that can be rotated to produce the necessary linear motion, significantly reducing device complexity while maintaining functionality.
3Adaptability or versatility
If a lifting mechanism is added to enable refill ejection, then the packaging becomes reusable and sustainable, but the device complexity increases
Solution Approach 1:
The lifting mechanism serves multiple functions: it lifts the refill device during ejection, provides structural support for the refill insertion process, and enables the overall reusability of the packaging system. By making the lifting mechanism multi-functional, the invention reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving packaging reusability.

Function Achieved in This Case
This solution enables substantial savings in packaging materials and reduces environmental contamination by allowing the packaging device to be reused and the refill device to be recycled, promoting sustainability.
Implementation Method 1
a threaded rod is fixedly arranged on the base; the first through hole is engaged with teeth of the threaded rod; the threaded rod passes through the first through hole and extends into the lifting platform main body; and the bottom plate can move along the threaded rod when the threaded rod rotates
