Solution Overview
Problem
Existing modular storage systems lack an efficient and secure mechanism for quickly coupling and decoupling utility modules, such as tool storage units, which can lead to instability during transport and usage.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a coupling mechanism is added to modular storage systems, then the ease of operation for coupling and decoupling modules is improved, but the device complexity increases
Solution Approach 1:
The coupling mechanism automatically engages and locks when modules are brought together, without requiring manual operation. The arms self-align and self-lock into the coupling pockets, making the system self-servicing for the coupling function.
Solution Approach 2:
The patent replaces complex manual mechanical coupling operations with a simplified system using spring-loaded arms and elastic deformation. The elastic arms naturally seek their locked position, substituting complex mechanical linkages with elastic energy storage and release.
2Reliability
If multiple arms are used to surround the projection, then the reliability of the coupling connection is improved, but the device complexity increases
Solution Approach 1:
The coupling mechanism uses an asymmetric arrangement where the arms are positioned at specific angles around the projection rather than uniformly distributed. This asymmetric placement provides sufficient stability while minimizing the number of arms needed.
Solution Approach 2:
The patent uses more arms than the absolute minimum required for stability. By providing slightly excessive structural support with multiple arms, the system achieves high reliability without requiring precisely optimized complex mechanisms.
3Strength
If a tension mechanism is added to lock the arms, then the strength of the coupling is improved, but the ease of operation for disengagement worsens
Solution Approach 1:
The tension mechanism uses elastic deformation of spring-loaded arms instead of complex mechanical locking systems. The arms store elastic energy when engaged and can be easily released by overcoming the spring force, replacing intricate mechanical release mechanisms with simple elastic energy release.
Solution Approach 2:
The coupling strength is adjusted by changing the elastic properties and pre-tension of the arms. By modifying material properties, arm dimensions, or initial spring tension, the system achieves strong coupling that can be easily released by applying a small force to overcome the elastic restoring force.
