Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the robot operates without protective fences to enable collaborative work with humans, then the scope of automation and ease of operation is improved, but the safety and risk reduction deteriorates
Solution Approach 1:
The patent applies beforehand cushioning by designing the tool with a resilient bearing that can absorb collision forces before they cause damage. The bearing is pre-configured with elastic elements that automatically activate upon collision, cushioning the impact and enabling safe evasive movements without requiring protective fences.
Solution Approach 2:
The patent implements dynamics by making the bearing resilient and flexible during movement phases, allowing the tool to perform evasive movements when colliding with humans or objects. The bearing dynamically changes its characteristics based on operational phase, being flexible during positioning and rigid during dispensing.
2Object-affected harmful factors
If the bearing is made resilient and flexible to enable evasive movements during collisions, then the safety and risk reduction is improved, but the manufacturing precision and stability deteriorates
Solution Approach 1:
The bearing dynamically switches between resilient/flexible state during movement and rigid/stable state during dispensing operations. This dynamic characteristic change allows the system to achieve both collision safety and manufacturing precision at different operational phases.
Solution Approach 2:
The patent employs a sensor system that provides feedback on the tool's position and collision status. This feedback enables the control system to compensate for bearing deformation and maintain precise line end positioning even when the bearing is in its resilient state, or to trigger corrective actions after collisions.
3Manufacturing precision
If the supply line is made rigid to prevent deformation during dispensing, then the manufacturing precision is improved, but the ease of operation and adaptability deteriorates
Solution Approach 1:
The supply line's rigidity is dynamically adjusted based on operational requirements. During movement and collision phases, the supply line remains flexible to allow tool adaptability and evasive movements. During dispensing operations, the supply line is stabilized or rigidized to ensure manufacturing precision and prevent deformation.
4Manufacturing precision
If the tool is equipped with a stabilizing device to block the bearing during dispensing, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The stabilizing device is designed to activate automatically based on operational conditions without requiring complex external control mechanisms. The device self-regulates the bearing's stability based on whether the system is in movement mode or dispensing mode, reducing overall device complexity while maintaining precision.
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 solution enhances the scope of automation, reduces risk potential, and allows for collaborative operation with humans by ensuring the tool can safely interact with humans and maintain process integrity, even in the event of collisions, while ensuring precise and controlled dispensing of viscous media.
Implementation Method 1
The bearing can be resilient and/or flexible. This will prevent damage. Due to the resilience to a position given before a collision, which can be brought about, for example, by spring force and/or elasticity
Implementation Method 2
The tool can have a heating device. The medium can be heated by the heating device, so that the flowability can thereby be influenced.
