Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity and cost associated with warehousing and producing webs of varying lengths for variable-length double locking cylinders result in material waste and increased costs, as existing solutions require numerous different web lengths and complex assembly processes.
Innovation Solution
A modular web system comprising a middle part with a thickened base element and extension parts, connected using pins, allowing for assembly of standard double lock cylinders with few middle parts of different lengths and extension parts of the same length, ensuring stability and safety while simplifying production and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple webs of different lengths are provided for variable-length double locking cylinders, then all standard double lock cylinders can be assembled, but warehousing becomes very complex and requires many different web lengths
Solution Approach 1:
The web is divided into a middle part and extension parts that can be assembled together. The middle part has a specific length suitable for standard double lock cylinders, while extension parts of standardized lengths can be added to achieve variable total lengths. This segmentation allows a single middle part design to serve multiple cylinder length requirements when combined with different extension parts.
Solution Approach 2:
Extension parts are designed to be attached to the middle part in a nested manner, where the extension part incorporates the middle part's connection interfaces. This allows the extension part to contain and build upon the middle part structure, creating a hierarchical assembly that simplifies the overall component inventory while maintaining versatility.
2Reliability
If webs are made of very strong and flexurally stable material to prevent tearing during break-in attempts, then security is improved, but material waste increases when cutting to different lengths
Solution Approach 1:
The web is segmented into a middle part and extension parts, where the middle part is manufactured to a standardized length that can be reused across different cylinder configurations. Only the extension parts need to be varied in length, significantly reducing the material waste associated with cutting multiple different-length webs from stock material.
Solution Approach 2:
The middle part is pre-manufactured to an optimal standardized length that accommodates the base requirements of all standard double lock cylinders. This preliminary sizing eliminates the need to cut and waste material for each individual cylinder length, as the middle part serves as a reusable base for all assemblies.
3Ease of manufacture
If modular system with few middle parts and extension parts of same length is used, then production and storage are simplified, but assembly stability and safety must be maintained
Solution Approach 1:
The web is divided into a middle part and extension parts with standardized dimensions and connection interfaces. This segmentation enables simplified production through standardized manufacturing processes and reduces storage complexity by limiting the variety of unique components. The modular nature maintains stability through precise interface design between segments.
Solution Approach 2:
The middle part is designed as a universal base component that can be combined with different extension parts to create webs for various cylinder lengths. This multi-functionality simplifies production and storage by using a single middle part design across all applications, while the standardized connection interfaces ensure assembly stability and safety.
