Solution Overview
Problem
Existing compact tool boxes are cumbersome and inefficient when used in corners or limited spaces due to their design, which hinders force transmission and leads to user difficulty and potential damage from applied torque.
Innovation Solution
A compact tool box design featuring a body with a driving groove and insertion groove system, integrated lateral walls, and a ratcheting mechanism that allows for efficient force application and storage of shanks, enabling smooth operation in tight spaces with reduced dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the tool box is designed with a compact size to fit in corners, then the profile is reduced and portability is improved, but the user cannot apply sufficient torque and force transmission is compromised
Solution Approach 1:
The patent repositions the driving groove from a central location to an offset position near one end of the handle body. This dimensional relocation creates asymmetric force application points, allowing the user to apply torque more effectively in limited spaces while maintaining a compact overall profile. The offset positioning enables better leverage utilization without increasing the tool box volume.
Solution Approach 2:
The patent creates localized structural features including a recessed portion at the end of the handle body and a specifically positioned driving groove. These local quality modifications concentrate the force application area, allowing efficient torque transmission through a small contact region while the rest of the handle body remains compact. The recessed portion provides a localized force-receiving area that enhances mechanical advantage.
2Ease of manufacture
If the driving groove is positioned centrally in the handle body, then the structure is symmetric and manufacturing is simplified, but the user cannot effectively apply force in limited spaces such as corners
Solution Approach 1:
The patent deliberately introduces asymmetry by positioning the driving groove offset from the center of the handle body toward one end. This asymmetric configuration allows the user to apply force more effectively in constrained spaces like corners, where symmetric designs fail. The asymmetric design accepts increased manufacturing complexity as a trade-off for significantly improved operational capability in limited spaces.
Solution Approach 2:
The patent segments the handle body into distinct functional zones: a driving groove region for force application, a recessed portion for force reception, and a bit storage area. This segmentation allows each zone to be optimized for its specific function, with the driving groove positioned independently of the centerline to maximize operational effectiveness in confined spaces.
3Shape
If the handle body width and height are kept equal for compact design, then the profile is reduced, but rotating the tool handle becomes laborsome and user force is limited
Solution Approach 1:
The patent moves the driving groove to an offset position near the end of the handle body, creating an asymmetric force application geometry. This dimensional change allows the user to apply rotational force more effectively by leveraging the offset distance, reducing the effort required to rotate the tool even when the handle body maintains equal width and height for compactness.
Solution Approach 2:
The recessed portion acts as an intermediary structure between the user's applied force and the rotational motion of the driving groove. By providing a localized force-receiving area at the offset position, the recessed portion mediates the force transmission, making rotation smoother and requiring less user effort while maintaining the compact equal-dimension handle body shape.

AI summary
A tool box includes a body having a front end and a force-receiving portion spaced from the front end. The body further includes first and second sides and two lateral walls. The front end includes a driving groove for receiving a shank in an operative position. A receiving space is defined between the lateral walls and has an opening. The force-receiving portion includes an insertion groove for receiving the shank in a storage position. The insertion groove is in communication with the driving groove of the body. The body further includes a first opening extending from one of the lateral walls through the insertion groove and a second opening extending from the other lateral wall through the insertion groove, allowing access to the shank in the storage position for manual removal of the shank from the insertion groove. A bit-receiving rack is removably received in the receiving space.
