Solution Overview
Problem
Conventional frame components for agricultural equipment, such as plow frames, require time-consuming and material-intensive manufacturing processes with potential for structural changes and dimensional inaccuracies due to welding, which affects their strength properties.
Innovation Solution
A frame component design using stamped parts with individual components having varying wall thicknesses and special material structures, allowing for adhesive connections without welds, enabling optimal material utilization and adaptation to specific load areas with form-fitting connections and clamping mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding processes are used to assemble frame components, then structural prerequisites for securely supporting add-on elements can be created, but structural changes in metallic materials occur leading to dimensional inaccuracies and reduced strength properties
Solution Approach 1:
The frame component is divided into multiple separate profile bodies that are connected through bonding technology rather than welded. Each profile body can be individually manufactured with precise dimensions, and the bonding connection maintains these dimensional accuracies without the heat-affected zone distortions that occur in welding.
Solution Approach 2:
The welding process (thermal/mechanical system) is replaced with bonding technology (chemical/adhesive system). This substitution eliminates the thermal effects that cause structural changes and dimensional inaccuracies in metallic materials, while still achieving secure connections for supporting add-on elements.
2Reliability
If conventional welded constructions are used for frame components, then structural integrity can be achieved, but time-consuming and material-intensive manufacturing processes are required
Solution Approach 1:
The frame component consists of multiple profile bodies that can be manufactured independently and simultaneously, then quickly assembled through bonding. This parallel manufacturing approach significantly reduces production time compared to sequential welding operations, while the bonding technology ensures structural integrity comparable to welding.
Solution Approach 2:
The connection method parameter is changed from welding (high temperature, slow cooling) to bonding (ambient or controlled temperature, rapid setting). This parameter change accelerates the manufacturing process while maintaining structural integrity, as bonding agents can cure quickly without the prolonged thermal cycles required for welding.
3Adaptability or versatility
If additional parts are welded onto frame components to create receptacles for add-on elements, then secure support for tools and equipment is achieved, but manufacturing effort and material consumption increase
Solution Approach 1:
The receptacles for add-on elements are merged into the profile bodies themselves rather than being separate welded attachments. The bonding technology allows these receptacles to be integrated during the manufacturing of the profile bodies, eliminating the need for additional welding operations and reducing overall manufacturing effort while maintaining adaptability.
Solution Approach 2:
The profile bodies are designed with multi-functionality, serving both as structural support elements and as integrated receptacles for add-on elements. This universal design approach, enabled by bonding technology, allows a single component to fulfill multiple functions without requiring additional parts or welding operations, thereby reducing manufacturing effort.
4Strength
If local reinforcements are implemented in welded frame components, then specific load requirements can be met, but manufacturing effort increases significantly
Solution Approach 1:
The profile bodies can be manufactured with locally varied wall thicknesses and material properties during the extrusion or molding process, allowing reinforcements to be built-in at specific locations without additional manufacturing effort. This local quality variation is achieved in the primary manufacturing step rather than requiring separate reinforcement operations.
Solution Approach 2:
Reinforcements are incorporated into the profile bodies during the initial extrusion or molding process rather than being added later through welding or attachment operations. This preliminary action eliminates subsequent manufacturing steps, as the reinforcements are already present in the correct locations and configurations before the bonding assembly takes place.

AI summary
The invention relates to a frame component for devices and machines, preferably agricultural devices and machines. In particular, the invention relates to a frame component for mounted tractor plows, trailer plows, and semi-mounted plows, comprising a hollow profiled body (1) which has an upper face, a lower face, and lateral faces and on which tools, tool supports, brackets, support wheels, and such attachment elements can be supported. The aim of the invention is to allow an individual design of a frame component with a simplified production but increased material properties. This is achieved in that the hollow profiled body (1) is made with at least two individual components (2, 3, 4) which are adhesively bonded to each other.
