Solution Overview

Problem

Existing bicycle racks for pickup trucks with bed shells or bed caps lack a strong and stable mounting system, leading to vibrations and instability during travel.

Innovation Solution

A bicycle rack with a special base plate assembly that can be clamped between the truck bed and the bed shell or bed cap, providing a sturdy and rigid attachment point for the bicycle rack.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a bicycle rack is mounted on a pickup truck bed with a bed shell or bed cap, then the bicycle rack can be installed on trucks with protective covers, but the mounting becomes unstable and causes vibrations during travel

Engineering Contradiction:

Improvecompatibility with bed shell or bed capVSAvoidmounting stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The base plate assembly is positioned within the space between the bed shell and the truck bed, nesting the mounting mechanism in the available gap space. This allows the rack to be mounted on trucks with bed shells while maintaining stability by utilizing the confined space effectively.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The base plate assembly transitions from a two-dimensional surface mount to a three-dimensional clamping structure that engages with the bed shell from multiple directions. The L-shaped configuration provides engagement in both horizontal and vertical dimensions, creating stable mounting despite the presence of the bed shell.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Device complexity

If a simple mounting system is used for the bicycle rack, then the device complexity is reduced, but the mounting becomes unstable and vibrates during travel

Engineering Contradiction:

Improvemounting system simplicityVSAvoidmounting stability

Core Design Contradiction:

Device complexityVSStability of the object's composition

Solution Approach 1:

The mounting system is divided into distinct functional segments: the base plate assembly for structural support, the clamp mechanism for securing to the bed shell, and the bicycle holding components. This segmentation allows each part to be optimized for its specific function while maintaining overall simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The base plate assembly merges multiple functions into a single integrated component: it provides structural support, creates anchoring points, and enables clamping to the bed shell. This consolidation reduces the number of separate parts needed while maintaining mounting stability.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A bicycle rack for a pickup truck that is reversibly attachable to the bed of a pickup truck that also has a bed shell or bed cap installed thereon. The bicycle rack of this invention sets off to the side of the truck bed like a saddle bag in order to provide clearance for the bed shell or bed cap. The bicycle rack includes a special base plate assembly that is a custom shaped rigid plate assembly. Base plate assembly has a complex shape that was designed to yield high strength and rigidity in order to provide solid and stable attachment of a bicycle to the bicycle rack and the bicycle rack to the pickup truck. The bicycle rack can be installed on the right side, the left side, or both sides of a pickup truck.
