Solution Overview

Problem

Existing weighing platforms with latticed load-bearing structures are either too heavy and immovable due to their weight, or they lack the necessary sturdiness and accuracy for high-load applications, often requiring complex and error-prone manual welding or heat bonding processes.

Innovation Solution

A weighing platform with a spatially shaped latticed load-bearing structure, featuring load-bearing elements with cuts for connecting elements, and profile panels with openings for screw connectors, allowing for press fitting or automated welding, which enhances sturdiness, reduces weight, and simplifies assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional latticed load-bearing structures are used for high loads, then load-bearing capacity is improved, but weight increases making the platform immovable

Engineering Contradiction:

Improveload-bearing capacityVSAvoidplatform weight

Core Design Contradiction:

StrengthVSWeight of stationary object

Solution Approach 1:

The patent applies local quality by using a lattice structure only in critical load-bearing zones rather than throughout the entire platform. The load-bearing shell covers only areas requiring high strength, while other areas use lighter construction, optimizing the weight-strength ratio locally where needed.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent employs composite construction by combining a lattice framework with a load-bearing shell covering, creating a hybrid structure that leverages the strength of the lattice where needed and the lightweight properties of the shell in other areas, reducing overall weight while maintaining load-bearing capacity.

Inventive Principle:

Principle #40Composite materials

2Ease of manufacture

If manual welding or heat bonding is used to join latticed elements, then structure assembly is achieved, but production errors increase and measurement accuracy decreases

Engineering Contradiction:

Improvestructure assemblyVSAvoidexecution tolerance

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent segments the load-bearing structure into modular latticed elements that can be manufactured separately with high precision using automated processes, then assembled using standardized connections. This segmentation enables quality control at the component level and reduces cumulative errors in the final structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces manual welding and heat bonding processes with mechanical connection systems such as bolting or clipping mechanisms. This substitution eliminates the harmful thermal effects of welding, ensures consistent connection quality, and allows for easier adjustment and quality verification during assembly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Strength

If welding or heat bonding processes are used, then load-bearing elements are joined, but local stress concentration occurs affecting durability and corrosion resistance

Engineering Contradiction:

Improvestructure integrityVSAvoiddurability and corrosion resistance

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The patent replaces thermal joining processes (welding and heat bonding) with mechanical connection methods. This substitution eliminates localized heat-affected zones that create stress concentrations and susceptibility to corrosion, while still achieving the necessary structural integrity through properly designed mechanical fasteners and connection details.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If latticed structures are made from stainless steel or acid-resistant steel, then corrosion resistance is improved, but material costs and machining complexity increase

Engineering Contradiction:

Improvecorrosion resistanceVSAvoidmachining complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by using corrosion-resistant materials only for the latticed load-bearing elements that are exposed to harsh environments, while non-critical components can use simpler, less expensive materials. This selective material application reduces overall complexity and cost while maintaining corrosion resistance where truly needed.

Inventive Principle:

Principle #3Local quality

AI summary

A weighing platform with a lattice load-bearing structure shaped spatially and made of load-bearing elements and connecting elements intersecting with them, affixed to a joint frame, where the load-bearing elements, in the place of intersection with the connecting profiles, have cuts in the shape adjusted to the shape of the connecting elements, and additionally the platform contains at least one load-bearing shell, measurement elements, regulated feet and connectors, where the connecting elements are located strictly in the cuts of the load-bearing structure at the depth, equal to height of the connecting elements and at the same time less than half of the height of the load-bearing elements, while to the bottom of the weighing platform at least two profile panels are fixed, with openings for the screw connectors, to which panels the measurement elements and regulated feet are fixed.
