Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal walls and fasteners are used to construct storage compartment units, then structural strength is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies composite materials by integrating metal reinforcement elements (such as metal corners, edges, and structural supports) within a thermoplastic or thermoset matrix. This creates a hybrid composite structure that combines the high strength of metals with the corrosion resistance and formability of polymers, achieving structural strength comparable to all-metal constructions while reducing complexity by eliminating separate fastening systems.
Solution Approach 2:
The invention merges multiple components into a single integrated modular unit. The storage compartment units are constructed by combining metal reinforcement elements, thermoplastic/thermoset panels, insulation layers, and fastening mechanisms into unified modular assemblies that can be attached to the truck body as complete units, thereby reducing device complexity while maintaining structural integrity.
2Ease of manufacture
If modular components are used for truck body assembly, then ease of manufacture and adaptability are improved, but structural integrity may be compromised
Solution Approach 1:
The patent divides the truck body into modular components including sidepack storage units, floor sections, and panel assemblies that can be manufactured separately and assembled together. Each module is designed with standardized attachment interfaces using mechanical fasteners, allowing for easy manufacturing and assembly while maintaining structural integrity through proper load path design and reinforcement at joint locations.
Solution Approach 2:
The modular components utilize composite construction with metal reinforcement embedded in thermoplastic or thermoset matrices, creating units that are both easy to manufacture (through molding and assembly) and structurally sound. The composite nature provides distributed strength throughout each module and at connection points.
3Strength
If traditional welding and adhesive methods are used for assembly, then structural strength is improved, but manufacturing time and environmental harm increase
Solution Approach 1:
The patent replaces welding and adhesive bonding with mechanical fastening systems including bolts, screws, clips, and interlocking mechanisms. These mechanical connections eliminate the need for thermal processes (welding) and chemical processes (adhesives), significantly reducing manufacturing time and eliminating associated environmental hazards while maintaining structural strength through properly designed fastener configurations and reinforcement.
Solution Approach 2:
The invention changes the assembly method from continuous processes (welding/adhering) to discrete mechanical fastening operations. This parameter change allows for parallel assembly operations, reduces cure times associated with adhesives, eliminates heat-affected zones from welding, and enables easier disassembly and reconfiguration, thereby reducing overall manufacturing time.
4Object-affected harmful factors
If aerodynamic features are added to sidepacks, then drag and noise are reduced, but device complexity increases
Solution Approach 1:
The patent incorporates aerodynamic features into the sidepack design including curved surfaces, rounded edges, and streamlined contours that reduce air turbulence, drag, and wind noise. These aerodynamic shapes are integrated into the modular sidepack units themselves rather than added as separate components, minimizing the increase in device complexity while achieving the desired aerodynamic performance.
