Tyre shelf and arrangement in a tyre storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre storage systems face challenges with complex and expensive stacking devices, and the risk of tyres falling during handling due to inadequate support structures.
Innovation Solution
A tyre shelving structure featuring a support beam with transversely fastened tyre support arms, where each support arm has a recess for secure fastening with removable fastening means, forming a notched or housing type joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welded structures are used for fastening support arms to support beam, then strength is improved, but ease of manufacture deteriorates
Solution Approach 1:
The support arm is divided into two separate parts: a main body and a notched portion. The notched portion is detachably coupled to the support beam through fastening means, allowing the joint to be assembled without welding while maintaining sufficient strength. This segmentation enables easier manufacture while preserving joint integrity.
Solution Approach 2:
Fastening means (such as bolts or screws) are introduced as an intermediary element between the support arm and support beam. These fasteners transmit loads between the components, providing a non-welded connection that is both strong and easy to manufacture. The notched portion acts as an intermediary structure that accommodates the fastening means.
2Ease of manufacture
If support arms are fastened with threaded fastening means, then ease of manufacture is improved, but reliability deteriorates
Solution Approach 1:
The joint structure combines multiple elements (notched portion, fastening means, support beam) into a composite connection system. This composite structure leverages the strengths of each component: the notched portion provides geometric interlocking, the fastening means provide removable attachment, and together they achieve both ease of manufacture and reliable connection.
Solution Approach 2:
The notched portion features curved or rounded geometry that complements the shape of the support beam. This curved notched design creates a housing-type joint that naturally guides and secures the fastening means, enhancing both the reliability of the connection and the ease of assembly compared to sharp-cornered or purely linear designs.
3Ease of manufacture
If notched or housing type joint is used, then ease of manufacture is improved, but strength deteriorates
Solution Approach 1:
The notched portion is pre-formed as an integral part of the support arm during manufacturing. This preliminary shaping of the notched geometry allows the joint to be assembled simply by inserting the notched portion into the support beam and securing it with fastening means, eliminating complex manufacturing steps while maintaining joint strength through proper geometric design.
