Pivotable Bit Seat Toolbox Design for Compact Storage and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional toolboxes are bulky and difficult to carry due to their thickness and volume, and they fail to provide a display effect when the bits are stored, as they cannot be placed upright, and the use of torsion springs increases costs and can lead to mechanical fatigue.
Innovation Solution
A toolbox design featuring a base with pivotable bit seats that can be extended or stored, allowing the toolbox to be placed in an inverted V-shape for display and easy carriage, with the bit seats retained in the extended position by the weight of the bits, eliminating the need for springs and enhancing usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bits are received in upright grooves in the base, then bits can be stored, but the toolbox has large thickness and volume making it difficult to carry
Solution Approach 1:
The bit seat is designed to be pivotable between a storage position (reducing volume) and an extended position (facilitating bit access). This dynamic configuration allows the toolbox to transition between compact storage mode and operational mode, resolving the contradiction between volume reduction and bit accessibility.
Solution Approach 2:
The bit grooves are arranged radially on the pivotable bit seat rather than in fixed upright grooves in the base. This dimensional reorganization allows bits to be accessed from the side when the seat is extended, rather than requiring upright storage that increases toolbox thickness.
2Ease of operation
If torsion springs are used to move bit seats to extended positions, then bits can be accessed easily, but part costs and assembling costs increase
Solution Approach 1:
The bit seat utilizes the weight of the bits themselves as the actuating force to pivot into the extended position for bit access. This self-service mechanism eliminates the need for external springs or motors, reducing part costs and assembling costs while maintaining ease of operation.
Solution Approach 2:
The patent replaces the mechanical spring system with a gravity-based passive mechanism. Instead of using elastic potential energy storage (springs), the system uses gravitational force on the bits to automatically position the bit seat, simplifying the mechanical system and reducing manufacturing complexity.
3Ease of operation
If torsion springs are used to extend bit seats, then bits can be removed easily, but the springs can fatigue and fail
Solution Approach 1:
The bit seat uses the bits' own weight as the actuating force, eliminating fatigue-prone mechanical components like springs. This self-weight actuation provides reliable, maintenance-free operation over the product lifetime.
Solution Approach 2:
The patent eliminates the use of fatigue-prone springs in favor of a passive gravity-based system. While springs are inexpensive, they have limited lifetimes due to fatigue; the replacement mechanism uses no such components, providing indefinite reliability.
4Reliability
If the toolbox is designed with conventional base and cover structure, then it can store bits, but it cannot be placed upright providing no display effect
Solution Approach 1:
The pivotable bit seat design allows the toolbox to assume different configurations including an upright inverted V-shape position for display purposes. This dynamic structural capability enables the toolbox to serve dual functions: compact storage and upright display, enhancing versatility without compromising storage reliability.
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
The design allows for a compact, lightweight toolbox that can be easily carried and displayed upright, providing easy access to bits while avoiding the costs and reliability issues associated with torsion springs, and maintaining functionality without a hook.
Implementation Method 1
The first abutment portion of the first bit seat abuts the first rib of the base under action of weights of the plurality of first bits, retaining the first bit seat is in the extended position

AI summary
A toolbox includes a base having a compartment with a bottom wall. A cover is pivotably connected to the base. A bit seat is received in the compartment and pivotably connected to the base. The bit seat includes a plurality of bit grooves for receiving bits. When the bit seat is in a storage position, a longitudinal axis of each bit groove is parallel to the bottom wall of the base, and the bits are received in the compartment. An abutment portion of the bit seat abuts a rib on the bottom wall when the bit seat is in an extended position. The cover and the base can be in an inverted V-shaped state and can be placed on a platform while the abutment portion of the bit seat abuts the rib under action of weights of the bits, retaining the bit seat is in the extended position.
