Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying brackets for vehicle cup holders are limited in size compatibility, requiring multiple designs to accommodate different cup holder sizes, leading to increased development costs and user inconvenience due to the need for new brackets with vehicle changes.
Innovation Solution
A carrying bracket with an adjustable expansion unit comprising a base unit, rotating unit, and expansion units, featuring through holes, spiral guide grooves, and adjustable wall supports, allowing for linear extension and secure fixation of various cup holder sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size carrying bracket is used, then the structure is simple and manufacturing cost is low, but it cannot accommodate different cup holder sizes
Solution Approach 1:
The carrying bracket employs expandable support members that can dynamically adjust their length through a rotating mechanism. The support members transition from a retracted state to an expanded state, allowing the bracket to adapt to different cup holder sizes while maintaining a compact form when not in use.
Solution Approach 2:
The support members are designed with a nested structure where the expanding components are housed within the bracket body when not in use. The support members can be inserted into and retracted within the bracket, similar to nested dolls, allowing for compact storage while providing extended functionality when needed.
2Adaptability or versatility
If multiple sets of carrying brackets are provided for different cup holder sizes, then size compatibility is improved, but development cost and manufacturing cost increase
Solution Approach 1:
The carrying bracket is designed as a universal solution that can accommodate multiple cup holder sizes through its adjustable support members. Instead of creating multiple specialized brackets for different sizes, this single design performs multiple size-matching functions, reducing the need for manufacturers to produce and stock multiple variants.
Solution Approach 2:
The bracket utilizes adjustable parameters through its expandable support members, allowing the physical dimensions of the bracket to change based on the required cup holder size. This parameter adjustment capability enables a single design to replace multiple fixed-size designs, simplifying manufacturing and inventory management.
3Reliability
If traditional outwardly expandable support members are used, then fixing effect is achieved, but the bracket is only suitable for small size range of cup holders
Solution Approach 1:
The support members incorporate a rotating mechanism that enables dynamic adjustment of their effective length. By rotating the support members, users can extend or retract them to match different cup holder diameters, maintaining reliable contact and fixing effect across a wide range of sizes rather than being limited to a fixed dimension.
