Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for dispensing disposable cutlery face inefficiencies in loading and dispensing multiple utensils, leading to space inefficiencies, waste generation, and jamming issues due to improper orientation and securing methods.
Innovation Solution
A module of disposable cutlery where at least two utensils are separably coupled using adhesives or a common formable material, allowing for secure grouping and easy decoupling for single-item dispensing, using methods like injection molding, welding, or applying adhesives to form continuous or intermittent coupling strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If multiple utensils are secured together via a band, wrapper, or cartridge, then space efficiency and storage compactness are improved, but waste is generated from the securing device or cartridge after use
Solution Approach 1:
The patent extracts the securing function from a separate band or wrapper and integrates it directly into the utensil structure through molded coupling features. The coupling features are formed as integral parts of the utensils during molding, eliminating the need for separate securing devices that would become waste after use.
Solution Approach 2:
The patent merges the securing function with the utensil structure itself by forming coupling features as integral parts of the utensils. The coupling features and utensils are created as a single unified structure through molding, combining the utensil and securing mechanism into one component system that reduces waste.
2Reliability
If utensils are loaded one-at-a-time into a dispenser, then dispensing reliability is improved, but loading efficiency and productivity deteriorate
Solution Approach 1:
The patent segments the group of coupled utensils into individual utensils through the dispensing mechanism. The coupling features allow utensils to be separated one-at-a-time from the group as they are dispensed, maintaining reliable single-unit dispensing while enabling efficient bulk loading of multiple coupled utensils into the dispenser magazine.
Solution Approach 2:
The patent performs preliminary coupling of multiple utensils together before loading into the dispenser. The utensils are pre-assembled into coupled groups with integrated coupling features, which are then loaded as units into the dispenser magazine, eliminating the need for manual one-at-a-time loading while ensuring proper orientation through the predetermined coupling geometry.
3Stability of the object's composition
If utensils are coupled securely together, then group stability is improved, but ease of separation for individual dispensing deteriorates
Solution Approach 1:
The patent creates a dynamic coupling system where the coupling features provide stable holding during normal handling and transport, but allow easy separation when force is applied during dispensing. The coupling geometry is designed to maintain group integrity until the dispensing mechanism engages, at which point the coupling can be cleanly broken to release individual utensils.
Solution Approach 2:
The patent utilizes changes in mechanical parameters through the coupling features. The coupling geometry is designed with specific strength characteristics that maintain group stability under normal conditions but allow controlled separation when sufficient force is applied during the dispensing process, transitioning from a stable coupled state to an separated individual state.
