Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connections are used to fasten equipment components, then secure attachment is achieved, but corrosion damage occurs and anti-corrosion coating is damaged
Solution Approach 1:
The patent introduces a mounting rail as an intermediary component between the vehicle body and equipment components. The mounting rail is attached to the vehicle body surface without penetrating it, using adhesive or friction-based fixation, thereby serving as a mediator that provides fastening functionality while preserving the integrity of the anti-corrosion coating and preventing corrosion damage to the vehicle body.
Solution Approach 2:
The patent replaces the traditional mechanical screw connection system with a mounting rail system that uses friction, adhesive bonding, or elastic retention mechanisms. This substitution eliminates the need for holes and threads in the vehicle body, thereby preventing corrosion while maintaining secure attachment of equipment components.
2Strength
If screw connections are used to fasten equipment components, then secure attachment is achieved, but component position cannot be changed easily
Solution Approach 1:
The mounting rail is designed with movable elements such as sliders, clips, or elastic retention mechanisms that allow equipment components to be easily repositioned along the rail. This dynamic design enables the component position to be adjusted without dismantling the entire fastening system, thereby providing adaptability while maintaining secure attachment during normal operation.
Solution Approach 2:
The fastening system is segmented into the mounting rail and the equipment component, with an interface that allows relative movement. The mounting rail is divided into multiple positioning zones or slots, enabling the equipment component to be securely fastened at different positions along the rail, thus achieving both secure attachment and position adjustability.
3Ease of manufacture
If conventional fastening methods are used, then simple installation is achieved, but rattling noises occur
Solution Approach 1:
The mounting rail acts as an intermediary that incorporates vibration-dampening features such as elastic elements, rubber inserts, or friction-based contact surfaces. These features absorb and dampen vibrations between the equipment component and the vehicle body, preventing rattling noises while maintaining installation simplicity through the modular rail design.
Solution Approach 2:
The mounting rail is designed with built-in vibration damping elements and friction-based contact surfaces that provide cushioning against vibrations before they can cause rattling noises. This beforehand cushioning is integrated into the fastening mechanism itself, eliminating rattling while keeping the installation process simple and straightforward.
4Adaptability or versatility
If mounting rail is used for variable positioning, then position flexibility is improved, but device complexity increases
Solution Approach 1:
The mounting rail is designed as a universal fastening system that can accommodate different types of equipment components through standardized interfaces, clips, or attachment mechanisms. This multi-functionality allows a single rail design to provide variable positioning for various components without requiring complex component-specific fastening systems, thereby limiting the increase in overall device complexity.
