Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex locking mechanism with multiple parts is used, then the locking function is achieved, but the manufacturing cost increases and reliability decreases
Solution Approach 1:
The patent merges the locking head, elastically deformable element, and internal part into a single integrated component. This consolidation eliminates the need for separate locking mechanisms, reducing the number of parts while maintaining the locking function, thereby improving reliability and reducing manufacturing complexity
Solution Approach 2:
The locking device utilizes the elastic deformation properties of the integrated element to automatically engage and disengage the locking head without requiring additional actuating mechanisms. The element's inherent elasticity provides the locking and release functionality, eliminating the need for complex external locking systems
2Volume of moving object
If a compact cap design is used, then the bottle size is reduced, but the space for the locking mechanism is limited
Solution Approach 1:
The locking head and elastically deformable element are nested within the internal part structure, utilizing the existing cap volume efficiently. The locking mechanism is integrated into the internal part rather than occupying additional space, allowing compact cap design while maintaining full locking functionality
Solution Approach 2:
The elastically deformable element functions as a flexible component within the compact cap structure. Its ability to deform and return to original shape provides the locking mechanism within minimal space, enabling compact design without compromising the locking function
3Length of moving object
If an elastically deformable element with large arc angle is used, then the locking head displacement is sufficient, but the cap space requirement increases
Solution Approach 1:
The elastically deformable element incorporates an arcuate portion with a curvature radius optimized to provide sufficient locking head displacement within the available cap space. The curved geometry allows the element to achieve the necessary travel distance while maintaining a compact form factor that fits within the cap volume
Solution Approach 2:
The design optimizes the arc angle and curvature radius parameters of the elastically deformable element to achieve the maximum practical displacement within the constrained cap volume. By carefully selecting these geometric parameters, sufficient locking head travel is obtained without requiring excessive cap space

Function Achieved in This Case
The design is economical, reliable, and user-friendly, with reduced manufacturing costs and improved ergonomics, facilitating easy assembly and disassembly while maintaining a compact and aesthetically pleasing form.
Implementation Method 1
The locking device by elastic deformation comprises a locking head movable between a holding position in which the inner part is held in the outer part and a release position in which the inner part can be removed from the outer part. The locking head is brought into the release position by elastic deformation of the elastically deformable element, by exerting manual pressure on the locking head.
