Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spare tire fixing mechanisms are inconvenient to assemble and disassemble, require repeated screw tightening or loosening, cannot adapt to different tire sizes, and lack storage for fixing members, leading to potential loss and increased labor consumption.
Innovation Solution
A multi-purpose spare tire rack with a fixing frame and member, featuring a connecting hole and limiting hole for secure attachment, symmetrical storage holes, and screw rods with locking nuts for easy assembly and disassembly, accommodating different tire sizes and preventing loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional screw fixing mechanisms are used to secure spare tires, then the spare tire can be fixed securely, but assembly and disassembly require repeated screw tightening or loosening which is inconvenient and time-consuming
Solution Approach 1:
The fixing mechanism is divided into separate components: a fixing frame with connecting holes and limiting holes, and removable fixing members (screw rods with locking nuts). This segmentation allows the fixing members to be quickly inserted and locked without threading screws, enabling rapid assembly and disassembly of the spare tire.
Solution Approach 2:
The fixing members are designed to be removable and replaceable rather than permanently fixed. The dynamic design allows users to quickly insert or remove fixing members by simply placing them into the connecting holes and securing with locking nuts, eliminating the need for repeated screw tightening and loosening operations.
2Adaptability or versatility
If a fixed spare tire rack design is used, then the structure is simple, but it cannot adapt to different tire sizes
Solution Approach 1:
The fixing frame is designed with universal connecting holes and limiting holes that can accommodate multiple types of fixing members (first screw rod, second screw rod, etc.). This universal design allows the same fixing frame to securely hold different tire sizes by simply changing the fixing members, achieving versatility without increasing frame complexity.
Solution Approach 2:
Different fixing members have varying lengths and configurations to adapt to different tire sizes and vehicle requirements. By changing the parameters of the fixing members (length, thread pitch, diameter) while keeping the fixing frame structure simple, the system achieves adaptability to various tire dimensions.
3Reliability
If fixing members are not stored on the rack, then the structure is simpler, but fixing members may be lost after multiple uses
Solution Approach 1:
The fixing members are stored within the fixing frame structure itself. The frame contains designated storage locations where fixing members can be placed when not in use, nesting the storage function within the existing frame structure without adding external storage components.
Solution Approach 2:
The storage function is merged with the fixing frame structure. The frame simultaneously serves as both the mounting structure for the spare tire and the storage container for the fixing members, combining multiple functions into a single integrated component.
4Ease of repair
If an integrated fixing structure is used, then manufacturing is simpler, but the structure cannot be assembled or disassembled for replacement
Solution Approach 1:
The fixing system is segmented into a permanent fixing frame and removable fixing members. This segmentation allows the fixing members to be easily replaced when worn or damaged, while the fixing frame remains as the stable mounting structure. The connecting holes and limiting holes provide standardized interfaces for assembly and disassembly.
Solution Approach 2:
The fixing frame is pre-manufactured with connecting holes and limiting holes in predetermined positions and configurations. This preliminary preparation of the frame structure enables quick assembly and replacement of fixing members without requiring complex alignment or modification during maintenance operations.
