Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the mesh size of the meshwork is made comparatively large to meet load requirements and reduce material input, then material use is advantageous, but the meshwork becomes unsuitable for packaging small-sized goods
Solution Approach 1:
The meshwork is segmented into two distinct components: a base layer made of laid fabric with crossing meshwork webs, and an additional close-meshed plastic net layer. This segmentation allows each layer to serve specific functions - the base layer provides overall structure and load-bearing capacity, while the plastic net layer provides fine mesh coverage for retaining small goods, thereby resolving the contradiction between material efficiency and adaptability to small-sized goods.
Solution Approach 2:
The invention uses a composite structure combining two different net types - a laid fabric meshwork base layer and a close-meshed plastic net overlay. This composite approach allows the meshwork to simultaneously achieve material efficiency through the stretched plastic net and versatility for small goods through the fine mesh pattern, directly addressing the technical contradiction.
2Adaptability or versatility
If the meshwork is made with a close-meshed plastic net to retain small parts, then suitability for small-sized goods is improved, but material input increases
Solution Approach 1:
The close-meshed plastic net is applied locally as an overlay on specific areas of the base layer, particularly in regions where small goods need to be retained. The plastic net is stretched to achieve the desired mesh pattern only where needed, rather than using a uniformly fine mesh throughout the entire meshwork, thereby reducing overall material input while maintaining suitability for small-sized goods.
Solution Approach 2:
Instead of using a fully close-meshed net throughout the entire meshwork structure, the invention applies the close-meshed plastic net partially as an overlay on the base layer. This partial action approach provides the necessary fine mesh coverage for small goods while minimizing material consumption by limiting the plastic net application to essential areas.
3Strength
If the meshwork webs are stretched to form diamond-shaped meshes with longitudinal diagonal transverse to tension ribbons, then load-bearing capacity is improved, but manufacturing complexity increases
Solution Approach 1:
The plastic net is pre-stretched during the manufacturing process to form the diamond-shaped mesh pattern with the longitudinal diagonal oriented transverse to the tension ribbons. This preliminary action of stretching creates the optimal load-bearing structure before the meshwork is assembled and put into service, ensuring maximum strength while using a straightforward production approach.
Solution Approach 2:
The invention changes the geometric parameters of the meshwork by stretching the plastic net to form diamond-shaped meshes with specific orientation (longitudinal diagonal transverse to tension ribbons). This parameter change optimizes the load-bearing capacity of the meshwork while the stretching process itself is a relatively simple manufacturing operation that does not significantly increase production complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The meshwork achieves improved dimensional stability and load-bearing capacity, suitable for packaging small-sized goods, while reducing material input and simplifying production.
Implementation Method 1
a fusion connection or heat sealing is provided between the tension ribbons lying in pairs against each other and between these tension ribbons and the meshwork webs resting against their inner surface during hot pressing of the meshwork
Implementation Method 2
the meshwork webs are tied to the tension ribbons via the thermoplastic bonding layer in a non-displaceable manner

AI summary
A meshwork has a layer forming a mesh, the mesh layer being disposed between parallel tension ribbons which are opposite one another in pairs. The tension ribbons have a thermoplastic bonding layer on the side facing the mesh layer and are connected to one another and to the mesh layer via the bonding layer. The mesh layer takes the form of a plastic net having meshwork webs which are connected to one another in a materially bonded manner and which are stretched and form diamond-shaped meshes, the longitudinal diagonals of which extend transversely to the tension ribbons.
