Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing truck caps are cumbersome to remove and store, often requiring multiple people and lack efficient storage solutions, limiting the versatility of pickup trucks.
Innovation Solution
A kit with rails and sliding masts, along with motorized lifting devices, allows for easy attachment and detachment of truck caps using lines, enabling single-person operation and synchronized lifting and lowering, with a control system for safe and efficient cap management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a truck cap is used to protect items and conceal contents, then protection and concealment are improved, but the truck bed becomes inaccessible for large items and the cap becomes difficult to remove
Solution Approach 1:
The patent replaces manual mechanical removal with an automated electric hoisting system. Motors mounted on the truck cab or overhead structure wind lines to lift the cap off the bed, eliminating the need for manual lifting and making removal as easy as pressing a button.
Solution Approach 2:
The patent introduces intermediate lifting components including hoists, lines, and sliding masts that act as mediators between the cap and the lifting force. These components transfer the lifting action smoothly, allowing single-person operation while protecting the cap during removal and storage.
2Adaptability or versatility
If a truck cap is removed for accessing large items, then accessibility is improved, but the cap becomes cumbersome to handle and store
Solution Approach 1:
The patent utilizes vertical space by mounting hoists overhead or on the cab, lifting the cap upward into the third dimension rather than requiring horizontal maneuvering. This vertical lifting approach simplifies storage by allowing the cap to be suspended in place or moved to an overhead storage position.
Solution Approach 2:
The hoisting system serves multiple functions: it removes the cap for accessibility, stores the cap in an elevated position, and can re-install the cap when needed. This multi-functional system eliminates the need for separate removal and storage operations, reducing overall complexity.
3Device complexity
If manual removal of truck cap is used, then simplicity is maintained, but multiple people are required and time is consumed
Solution Approach 1:
The patent replaces manual mechanical effort with electric motors that automatically wind lines to lift the cap. This substitution maintains operational simplicity from the user perspective while dramatically increasing productivity, allowing single-person operation and reducing removal time from minutes to seconds.
Solution Approach 2:
The hoisting system is designed to be self-operating once activated. The motor automatically winds the line, the sliding mast moves along the rail, and the cap is lifted without requiring the operator to physically guide or support it throughout the process, enabling true single-person operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables solo operation for installing and removing truck caps, reduces wear on lifting devices, and provides safe, synchronized lifting and lowering, extending the cap's usable life and enhancing truck versatility.
Implementation Method 1
a motor and transmission coupled to the drum to apply a torque thereto
Implementation Method 2
a sled which is captured by the rail, and is slidable along the rail

AI summary
The invention is a kit for attaching to a truck cap to enable the cap to be lifted off of and lowered onto a truck by lines from above. The kit includes: a first rail and a second rail, each configured to attach to the truck cap; a first pair of sliding masts for releasably attaching to the first rail and a second pair of sliding masts for releasably attaching to the second rail. Each of the sliding mast includes: a sled which is captured by the rail, and is slidable along the rail, and is adapted to be secured at various points along the rail; and a brace with one end attached to the sled and the other end adapted to receive one of the lines. In another aspect, the kit includes multiple lifting devices.
