Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient and versatile mechanisms for detachably attaching and interlocking utility modules, such as storage containers and tool boxes, to form modular assemblies that can be easily assembled and disassembled.
Innovation Solution
A coupling mechanism featuring male and female couplers with locking ribs and tongues, along with locking latches, allows for secure detachable attachment and interlocking of utility modules, enabling sliding and vertical stability without requiring complex assembly steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detachable coupling mechanisms are used to attach utility modules, then ease of assembly and disassembly is improved, but structural stability and reliability may deteriorate
Solution Approach 1:
The coupling mechanism employs nested structural elements where the locking tongue fits within a recess in the locking rib, creating a nested interlocking arrangement that provides stable attachment while remaining detachable. The locking tongue is received within the locking rib structure, forming a nested configuration that ensures reliability.
Solution Approach 2:
The coupling mechanism is divided into separate functional segments: a male coupler with locking tongue, a female coupler with locking rib, and a distinct recessed engagement area. This segmentation allows each component to perform its specific function while maintaining overall structural integrity and ease of assembly.
2Reliability
If locking mechanisms with multiple components are used to prevent unintended separation, then reliability is improved, but device complexity increases
Solution Approach 1:
The coupling mechanism merges multiple functions into integrated components. The locking rib simultaneously provides structural support, defines the engagement recess, and acts as the locking element. The locking tongue combines the protruding element, engagement feature, and detachment interface into a single integrated component, reducing overall complexity.
Solution Approach 2:
The coupling mechanism is designed as a universal system where the same male and female coupler design can be applied to various utility modules. The locking rib and locking tongue configuration serves multiple purposes: structural connection, positioning alignment, and secure locking, eliminating the need for separate specialized components.
3Ease of operation
If sliding engagement paths are used for assembly, then ease of operation is improved, but risk of unintended displacement increases
Solution Approach 1:
The coupling mechanism incorporates a preliminary sliding engagement phase where the locking tongue is inserted into the recess defined by the locking rib along a sliding path. This preliminary action guides the modules into proper alignment before the final locked position is achieved, ensuring both ease of assembly and subsequent stability.
Solution Approach 2:
The locking rib and locking tongue are designed with asymmetric geometries where the locking tongue has a specific profile that matches the recess shape. This asymmetry ensures that the modules can easily slide into engagement in the correct orientation while preventing unintended displacement in other directions, as the asymmetric shapes do not permit movement without disengagement.
