Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid cantilever arms are used in handling devices, then structural strength and stability are improved, but damage to the arms and unwanted adhesion of flat blanks occur
Solution Approach 1:
The patent replaces rigid cantilever arms with elastic cantilever arms that can dynamically adapt their flexibility. The elastic arms deform under load to distribute contact forces gradually, preventing sudden impacts that cause damage and adhesion. This dynamic flexibility allows the system to maintain strength while reducing harmful effects during operation.
Solution Approach 2:
The patent changes the physical parameter of the cantilever arms from rigid to elastic, modifying their mechanical properties. By selecting materials or designs with appropriate elastic moduli, the arms can control their degree of flexibility to optimize the balance between structural strength and prevention of damage/adhesion during handling operations.
2Object-affected harmful factors
If flexible or elastic boom arms are used, then unwanted adhesion of flat blanks is reduced, but device complexity increases to ensure elasticity and minimize wear
Solution Approach 1:
The patent segments the cantilever arm into multiple parts or uses a modular design where the elastic element can be independently replaced. This allows the complex elastic component to be swapped out when worn, simplifying maintenance and reducing overall system complexity while maintaining the adhesion-preventing benefits.
Solution Approach 2:
The patent employs easily replaceable elastic cantilever arms that can be quickly swapped when worn. By using simple, low-cost elastic materials or components, the system maintains the benefits of flexibility for preventing adhesion while minimizing the impact of wear through straightforward replacement rather than complex repair mechanisms.
3Object-affected harmful factors
If elastic cantilever arms are used, then contact force dissipates gradually preventing adhesion, but wear on boom arms and bearings increases
Solution Approach 1:
The elastic cantilever arms dynamically absorb and dissipate contact forces through controlled deformation, preventing sudden impacts that cause wear. The gradual force distribution reduces stress concentrations on bearings and connection points, minimizing wear while maintaining adhesion prevention benefits.
Solution Approach 2:
The elastic nature of the cantilever arms provides beforehand cushioning by absorbing impact energy during normal operation. This pre-existing elasticity acts as a cushion against wear-generating shocks and vibrations, protecting bearings and connection points from excessive wear while maintaining the force dissipation needed to prevent adhesion.
Applied Scientific Principles
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 tool enhances the stability and safety of pallets by reducing the risk of adhesion and damage, enabling efficient handling and transportation of flat blanks without sticking issues, while allowing for easy replacement of worn-out cantilever arms.
Implementation Method 1
at least one means, each of which can establish a detachable connection to the respective flat blank, so that the respective flat blank is fixed to the working tool via the detachable connections of the means
Implementation Method 2
preferred embodiments may include at least one suction head, so that the respective flat blank can be fixed to the working tool by negative pressure via the means designed as suction heads
Implementation Method 3
Flexible or elastic boom arms, on the other hand, offer the advantage that the contact force exerted between the gripper and the intermediate layer upon contact is not completely released at a specific point in time, but rather dissipates gradually
