Tubular Container Compensation Device with Shape Memory Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tubular containers with compensation devices are complex in design and costly to produce, as they are often tailored to specific container dimensions, and their integration with a hinged stopper can interfere with the opening/closing mechanism, reducing the efficacy of the compensation action.
Innovation Solution
A tubular container with a compensation device featuring a deformable connection between a large and small base, secured by a fastening mechanism with shape memory elements that exert friction forces on the container's internal wall, allowing easy and flexible integration with various container sizes and types, including those with hinged stoppers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compensation device is integrated into the container bottom, then protection against impacts and jolts is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The compensation device is divided into two functional parts: a compensation means (spring element) and a fastening means (attachment mechanism). This segmentation allows each part to be optimized independently and simplifies manufacturing compared to integrated solutions.
Solution Approach 2:
The compensation device is designed to be universally applicable to different container types and sizes. The fastening means can be adapted to various container bottoms without requiring custom-designed compensation devices for each container variant, reducing overall complexity.
2Reliability
If a compensation device is tailored to specific container dimensions, then compensation effectiveness is improved, but adaptability and manufacturing cost worsen
Solution Approach 1:
The compensation device incorporates universal fastening means that can be attached to different container bottoms. The compensation means is designed with adjustable characteristics, allowing the same device to effectively compensate for impacts in containers of varying dimensions without requiring custom design for each size.
Solution Approach 2:
The compensation device allows for parameter adjustments (such as spring stiffness, pre-compression force, or geometric dimensions) to optimize performance for different container types. This enables a single device design to adapt to various container dimensions while maintaining compensation effectiveness.
3Stability of the object's composition
If a compensation device is integrated with the closure means, then structural stability is improved, but the opening/closing mechanism functionality deteriorates
Solution Approach 1:
The compensation device is positioned at the container bottom, separate from the closure means. This spatial segmentation eliminates interference with the hinged stopper's opening and closing operations while still providing structural stability through the container bottom integration.
Solution Approach 2:
The compensation function is extracted from the closure means and relocated to the container bottom. This extraction resolves the conflict between compensation effectiveness and closure mechanism operation, allowing both functions to perform optimally without mutual interference.
4Manufacturing precision
If a complex compensation device is used, then compensation precision is improved, but manufacturing cost and ease of manufacture worsen
Solution Approach 1:
Dividing the compensation device into modular components (compensation means and fastening means) simplifies manufacturing. Each module can be produced using standard processes and then assembled, achieving precise compensation characteristics without requiring complex integrated manufacturing.
Solution Approach 2:
Manufacturing precision is achieved through controlled parameter specifications (material properties, geometric dimensions, pre-stress values) rather than complex device architecture. This allows standard manufacturing processes to produce precise compensation devices at lower cost.
