Tool Case Receptacle Positioning via Dynamic Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool cases lack flexibility in accommodating tools and small parts, as they often require fixed positions for the receptacle, limiting their usability based on the size and type of items stored.
Innovation Solution
A tool case design featuring a pivotable cover with adjustable fastening devices that allow the receptacle to be fixed in multiple positions on the inside of the cover, enabling flexible placement and use of space based on the items stored, including latching devices with undercuts and a spring tongue for secure and visual confirmation of the latched state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the receptacle is fixed in a fixed position on the inside of the lid, then the structure is simple and stable, but the flexibility and adaptability of the case is reduced
Solution Approach 1:
The patent implements a dynamic positioning system where the receptacle can be moved to different positions on the lid's inner surface. Multiple first fastening devices are distributed at different locations, allowing the receptacle to be repositioned according to storage needs. This dynamic adaptability resolves the contradiction by enabling flexibility without requiring a completely complex reconfiguration system.
Solution Approach 2:
The fastening system is designed with universal compatibility - the same first and second fastening devices work at all positions. The second fastening device on the receptacle can engage with any of the multiple first fastening devices on the lid, creating a universal interface that simplifies the overall system while providing multiple positioning options.
2Adaptability or versatility
If the receptacle can be positioned in multiple locations, then the adaptability is improved, but the ease of operation is reduced due to alignment requirements
Solution Approach 1:
The fastening system is designed to be self-aligning. The second fastening device on the receptacle automatically finds and engages with one of the first fastening devices on the lid without requiring precise manual alignment. The geometric design of the fastening devices ensures that once the receptacle is placed near a first fastening device, the components naturally guide themselves into the locked position, eliminating complex alignment procedures.
3Reliability
If locking devices are used to secure the receptacle, then the reliability of fixation is improved, but the ease of operation is reduced due to locking mechanisms
Solution Approach 1:
The locking mechanism operates automatically through the interaction of the first and second fastening devices. When the receptacle is positioned near a first fastening device, the second fastening device automatically engages and locks into place without requiring manual activation. The user simply needs to place the receptacle near the desired position, and the self-service locking mechanism handles the securement, maintaining both reliability and ease of operation.
4Adaptability or versatility
If the lid interior is made flat, then the space utilization is improved, but the adaptability for different tool sizes is reduced
Solution Approach 1:
The lid's inner surface is segmented into multiple zones with different geometric characteristics. Rather than being uniformly flat or uniformly contoured, the lid has distinct regions that can accommodate different tool shapes and sizes. The receptacle can be positioned in different segments depending on what needs to be stored, providing adaptability while maintaining an overall simple lid structure.
