Split-Handle Composite Package for Ergonomic Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite packages with multiple individual containers are cumbersome and cause strain due to their bulkiness and weight, making them difficult to carry and handle, as they often require heavy lifting and can lead to musculoskeletal issues, and breaking them down loses the advantage of a single, easily transportable package.
Innovation Solution
A composite package design featuring a handle that splits into sub-handles along pre-cut lines, allowing secondary packages to be easily separated while maintaining a sub-handle for each, ensuring ergonomic carrying and reducing strain by distributing weight more evenly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a composite package contains a large number of individual containers bundled together, then the total volume of product increases, but the package becomes bulky and difficult to carry in one hand
Solution Approach 1:
The composite package is divided into multiple secondary packages, each containing a subset of primary containers. This segmentation allows the total product quantity to be maintained while reducing the bulkiness of any single package, making them easier to carry and handle individually.
Solution Approach 2:
The handle is designed with a separation line that allows it to be divided into multiple sub-handles. This dimensional change in the handle structure enables the single composite package to be split into multiple separable units, each with its own carrying handle, thus improving ease of carrying while maintaining total product quantity.
2Quantity of substance
If a composite package is made heavy and bulky to contain sufficient product volume, then the product quantity increases, but it creates high degree of muscle and joint strain in the user
Solution Approach 1:
By dividing the composite package into multiple secondary packages, the weight and bulk of any single package is reduced. This segmentation decreases the muscle and joint strain on users while maintaining the total product quantity across all secondary packages combined.
3Strength
If the handle is designed to be strong and intact to hold all primary packages, then the structural integrity increases, but it becomes difficult to separate individual secondary packages
Solution Approach 1:
A separation line is pre-formed in the handle at strategic locations. This preliminary action creates a weak point in the handle structure that allows easy separation into sub-handles when needed, while the rest of the handle maintains its full strength to hold all primary packages securely during transport.
Solution Approach 2:
The separation line acts as an intermediary element within the handle structure. It provides a controlled weakness that enables easy separation of secondary packages while the surrounding handle material maintains structural integrity for strong holding capability.
4Volume of stationary object
If only 2 or 4 individual containers are placed in each secondary package, then the composite package size is reduced, but the individual packages must be large and unwieldy to yield sufficient product volume
Solution Approach 1:
The composite package is segmented into a specific number of secondary packages (2-4), each containing an optimized number of primary containers. This segmentation creates individual packages that are compact and manageable in size while the total volume across all secondary packages provides sufficient product quantity.

AI summary
A composite package (100) comprises a plurality of primary packages (104) and a handle (108) attached at two extremities (110, 708) thereof to said composite package (100), the plurality of primary packages (104) being gathered into several secondary packages (102a, 102b), wherein said handle (108) comprises at least one separation line (112) which divides said handle (108) into a plurality of sub-handles (114a, 114b) each attached at the extremities thereof to one of the secondary packages (102a, 102b), such that when one of said plurality of secondary packages (102a, 102b) is extracted from the composite package (100), said handle (108) separates along said at least one separation line (112) into a plurality of sub-handles (114a, 114b) each attached to said one of the secondary packages (102a, 102b) and retained therewith.
