Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parts are attached to main body by engagement between protrusions and grooves, then assembly is simple and reliable, but disassembly becomes time-consuming
Solution Approach 1:
The patent applies vibratory motion to the removal device, causing the roller to vibrate against the engaged parts. This vibration generates impact forces that break the engagement between protrusions and grooves, enabling rapid disassembly without manual manipulation of each component.
Solution Approach 2:
The removal device employs periodic vibratory motion through the roller, creating repeated impact cycles on the engaged parts. This periodic action accumulates sufficient force to overcome the engagement resistance of multiple parts simultaneously, significantly reducing disassembly time compared to static removal methods.
2Ease of operation
If multiple parts are removed sequentially by manual manipulation, then each part can be inspected, but the overall removal process becomes time-consuming
Solution Approach 1:
The removal device segments the removal process by using a roller that contacts multiple parts simultaneously along its surface. Different portions of the roller apply force to different parts, enabling parallel removal of multiple components while maintaining the ability to inspect removed parts individually.
Solution Approach 2:
The patent merges the removal function for multiple parts into a single roller component. This consolidation allows simultaneous engagement with and removal of multiple parts through one unified mechanism, dramatically increasing productivity while the sequential ejection of removed parts preserves inspection capability.
3Force
If a pressing force is applied to remove parts, then detachment is achieved, but deformable parts may be damaged
Solution Approach 1:
The vibratory motion of the roller delivers impact forces that are concentrated in time but distributed in effect. The vibration creates micro-movements and reduces friction between engaged surfaces, allowing parts to be loosened and removed with less overall pressing force, thereby preventing deformation of delicate components.
Solution Approach 2:
The patent changes the temporal characteristics of the applied force by using vibratory motion instead of static pressing. This parameter change transforms a continuous force application into pulsed impact forces, which are more effective at breaking engagement without causing cumulative deformation of deformable parts.
