Solution Overview

Problem

Existing driver bit containers have limited space utilization, require excessive parts and complex assembly, leading to high manufacturing costs and reduced bit capacity due to their monofunctional design and independent container components.

Innovation Solution

A driver bit container design featuring a main body with longitudinal cavities and symmetrical containers, along with two pivoted caps that rotate to cap onto the containers, utilizing the space efficiently and reducing parts for easier assembly and increased bit capacity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the main container with bit containing slots is designed as an independent part that pivots with the box main body to perform rotation function, then the rotation function is achieved, but the box main body can only act as a capping body, resulting in poor space utilization and limited containing space

Engineering Contradiction:
Improverotation functionVSAvoidcontaining space
Core Design Contradiction:
Adaptability or versatilityVSVolume of stationary object

Solution Approach 1:

The patent merges the container body and the rotating cap into a single integrated structure. The cap is designed with bit containing slots and pivots directly on the container body, eliminating the need for a separate rotating container component. This integration allows the cap to perform both the capping function and the rotation function, while the container body provides full containing space without being limited to a purely structural role.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If prior arts adopt components with mono function, then the design is simple, but it causes hassles of excessive parts, high molding costs, and complicated assembly

Engineering Contradiction:
Improvedesign simplicityVSAvoidnumber of parts
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The cap in the patent is designed as a multi-functional component that simultaneously serves as a cover, a container with bit storage slots, and a rotating mechanism. This multi-functionality eliminates the need for separate components for each function, reducing the total number of parts while maintaining design simplicity and lowering molding costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Device complexity

If the box main body acts purely as a capping body, then the structure is simplified, but the space utilization is poor and containing capacity is limited

Engineering Contradiction:
Improvestructural simplicityVSAvoidbit capacity
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The patent combines the storage function with the capping function by integrating bit containing slots directly into the cap structure. The container body remains structurally simple as a single-piece molded component, while the cap attached to it provides additional bit storage capacity. This merging allows the container body to maintain its structural simplicity while the overall system achieves enhanced bit capacity through the integrated cap design.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A driver bit container comprises: a main body, a clip and two containing caps. In the center of main body sets a longitudinal cavity for containing bit holders and there are two symmetrical containers on both sides of the longitudinal cavity with each of them divided longitudinally into two parts: a row of containing slots and an elongated concave. The clip is mounted on the backside of, and can rotate against the main body. Each of the containing caps has a row of side containing slots and a side elongated concave to cooperate with the said elongated concave and said containing slots respectively. Therefore, the invention has features of capability of containing more bits and easy to use.
