Spare Wheel Jack Holder With Sliding Arms for Quiet Tool Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel jack storage systems for vehicles are inconvenient due to separate structures that require customization based on vehicle dimensions, leading to noise and complexity during travel and maintenance, and are cumbersome to store and retrieve.
Innovation Solution
A wheel jack holder with sliding members and holder arms that can be easily mounted and detached from a spare wheel, featuring an elastic member for secure attachment to the wheel rim and integrated tool grooves for storing tools like a wheel wrench and toe hook within the holder base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a separate structure is used to accommodate tools in the spare wheel, then tools can be stored, but the structure must be customized for each wheel dimension and causes noise during travel
Solution Approach 1:
The holder base is integrated directly into the spare wheel structure, eliminating the need for separate accommodating structures. The holder base includes receiving portions that directly hold tools and a wheel jack, merging the storage function with the wheel itself, thereby eliminating noise caused by separate structures moving during travel.
Solution Approach 2:
The holder base is designed with a universal structure that can accommodate different wheel dimensions without customization. It includes a receiving portion for tools and a supporting portion for the wheel jack, allowing one design to serve multiple vehicle types and wheel sizes.
2Ease of operation
If a separate structure is used to store tools, then tools are organized, but the structure must be removed and stored separately when replacing wheels
Solution Approach 1:
The holder base is integrated into the spare wheel, combining tool storage with the wheel itself. When the wheel is removed for replacement, the tools and wheel jack remain in the holder base, eliminating the need to separately remove and store the tool storage structure.
3Ease of operation
If tools are stored in the spare wheel using a separate structure, then tools are accessible, but the structure adds complexity to the system
Solution Approach 1:
The holder base integrates tool storage and wheel jack support into a single structure that is part of the spare wheel assembly, reducing the number of separate components and simplifying the overall system while maintaining tool accessibility.
Solution Approach 2:
The holder base serves multiple functions: storing tools, supporting the wheel jack, and integrating with the spare wheel structure. This multi-functional design reduces the need for multiple separate components, thereby reducing system complexity.
4Device complexity
If the holder arms are fixed, then the structure is simple, but they cannot adapt to different wheel rim sizes
Solution Approach 1:
The holder arms are designed to be movable rather than fixed, allowing them to adjust their position to fit different wheel rim sizes. The arms can be moved outward to engage with larger rims and inward for smaller rims, providing adaptability without requiring multiple fixed structures for different sizes.

AI summary
A wheel jack holder for a vehicle may include a holder base having at least one sliding member formed at each of first and second side portions of the holder base, whereby a wheel jack is configured for being placed on the holder base; and a pair of holder arms, each having a sliding rod formed at a first surface thereof, wherein the sliding rod is slidably inserted into a hole of the sliding member. The pair of holder arms may move away from each other when receiving force from the wheel jack to be fixed to a wheel rim of a wheel.
