Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food packaging bodies fail to effectively accommodate and protect diverse food sizes and types, ensuring quality during transport and storage while providing aesthetic display.
Innovation Solution
A food packaging body with a tray and lid design featuring downward recessed and upward protruding cavities, allowing flexible accommodation and three-dimensional display of foods, with adjustable cavity depths and optional sealing for different food requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If trays with downward recessed cavities of uniform size are used, then the packaging structure is simple and easy to manufacture, but it is difficult to provide effective protection to foods of various sizes and types and lacks aesthetic appeal
Solution Approach 1:
The tray is divided into multiple independent cavities of different sizes and shapes, each cavity being a segmented unit that can be independently designed to fit specific food items. This segmentation allows the single tray to accommodate diverse food types while maintaining manufacturing simplicity through modular cavity design.
Solution Approach 2:
Different regions of the tray are designed with locally optimized cavity characteristics - some cavities are deeper for tall items, others are wider for flat items, and some have irregular shapes for specific food geometries. This local quality variation enables effective protection and aesthetic display of various foods without complicating the overall tray manufacturing process.
2Device complexity
If trays with downward recessed cavities of uniform size are used, then the packaging structure is simple, but it results in monotone display and lacks aesthetic feelings
Solution Approach 1:
The tray incorporates asymmetric cavity designs where cavities vary in depth, width, and shape rather than using uniform symmetric patterns. This asymmetry creates visual interest and aesthetic appeal in the food display while the cavities remain functionally optimized for their specific food items, balancing complexity with beauty.
Solution Approach 2:
The design transitions from two-dimensional uniform cavity patterns to three-dimensional varied cavity structures with different depths and profiles. This dimensional variation creates visual depth and aesthetic appeal in the packaging while maintaining relatively simple manufacturing through standard molding techniques.
3Ease of manufacture
If uniform downward recessed cavities are used, then manufacturing is easy, but it is difficult to guarantee effective protection during transport and storage
Solution Approach 1:
The tray is segmented into multiple independently optimized cavities, each designed to cradle specific food items according to their shape and size. This segmentation ensures that each food item is individually protected during transport and storage, preventing collisions and frictions, while the overall tray structure remains simple to manufacture.
Solution Approach 2:
Each cavity is designed with local quality characteristics tailored to the specific food it protects - varying depths, widths, and shapes provide customized protection for different food types. This localized optimization ensures reliable protection during transport and storage without requiring complex overall packaging structures.

AI summary
The present disclosure provides a food packaging body including a tray and a lid located above the tray, and the tray has two or more downward recessed cavities, wherein the lid has upward protruding cavities which are less than the downward recessed cavities, and each of the upward protruding cavities is corresponding to the position of a downward recessed cavity. The present disclosure provides a combination packaging body including an outer packaging component, and at least one food packaging body according to the present disclosure is accommodated in the outer packaging component. The food packaging body of the present disclosure can achieve accommodation of foods of different sizes and types in one packaging body and/or three-dimensional and patchwork food display at different levels in one packaging body and can seal a part of the cavities according to the requirements of different food.
