Inner Buckling Tool Box Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool boxes face challenges in miniaturization due to the need for internal locking mechanisms, which reduce internal space and are prone to damage or unintended detachment when carrying heavy tools.
Innovation Solution
An inner buckling type tool box design featuring a locking member that slides parallel to the housing wall, reducing deep space occupation and maintaining capacity, utilizing a pushing member and elastic member to facilitate easy opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the locking mechanism is arranged at the outside of the tool box, then the internal space capacity is maintained, but the locking mechanism is prone to damage and unintended detachment
Solution Approach 1:
The locking mechanism is extracted from the traditional external position and repositioned to the inner surface of the first free wall. This allows the locking mechanism to be protected within the housing structure while still performing its locking function, resolving the contradiction between maintaining internal space capacity and ensuring locking stability.
2Reliability
If the locking mechanism is arranged at the inside of the tool box, then the locking mechanism is protected, but the deep space required for movement greatly reduces the internal space capacity
Solution Approach 1:
The locking member's movement direction is changed from a deep longitudinal axis to a transverse direction parallel to the first free wall. This dimensional change allows the locking mechanism to move laterally within the accommodating portion rather than requiring deep space, thus protecting the locking mechanism while maintaining internal space capacity.
3Productivity
If the locking mechanism carries heavy tools, then the tool box capacity is utilized, but the locking mechanism is prone to unintended detachment when impacted
Solution Approach 1:
The locking mechanism is segmented into multiple components: a locking member with a locking portion, a pushing member, and an elastic member. This segmentation allows each component to perform a specific function - the locking member engages with the locking portion, the pushing member actuates the locking member, and the elastic member provides restoring force - working together to securely hold heavy tools and prevent unintended detachment.
4Reliability
If a traditional internal locking mechanism is used, then the locking function is achieved, but the deep space required for movement reduces the internal space capacity
Solution Approach 1:
The locking member is designed to move along a transverse direction parallel to the first free wall rather than along a deep longitudinal axis. The accommodating portion on the inner surface of the first free wall provides the movement space in this transverse direction, enabling the locking mechanism to function effectively while minimizing deep space occupation and maximizing internal space capacity.
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 enhances the tool box's capacity by minimizing deep space usage while providing a robust and intuitive locking mechanism that prevents unintended detachment, even when carrying heavy tools.
Implementation Method 1
The elastic member is configured to apply an elastic force to drive the locking member and make the locking member having a movement tendency to move from the open position to the closed position

AI summary
An inner buckling type tool box includes a first housing, a second housing, a locking member, a pushing member, and an elastic member. An inner wall of the first housing is provided with an accommodating portion to accommodate a locking member and a pushing member located between the inner wall and the locking member. The pushing member enables to slide vertically relative to the inner wall to drive the locking member to slide in a direction parallel to the inner wall, so that the locking member is selectively to be engaged with or disengaged form the second housing. Through a change in the moving direction, the occupation of deep space can be reduced greatly to maintain the capacity of the tool box.
