Solution Overview

Problem

Folding cases lack a robust and durable locking system that can withstand impacts and ensure secure closure, leading to potential unintentional opening during use or transport, which affects safety and longevity.

Innovation Solution

A single-piece centering locking system integrated with a spring mechanism that enhances centralization, assembly ease, and durability, comprising two sets of springs that provide coordinated movement for locking and unlocking the folding sidewalls.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional locking systems are used in folding cases, then the cases can be assembled and locked, but the locking system lacks robustness and may fail under impacts or excessive loads

Engineering Contradiction:
Improvelocking system robustnessVSAvoidlocking system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the centralizing system and locking system into a single unified structure. The centralizing pins and locking pins are combined in one component, eliminating the need for separate centralizing and locking mechanisms. This merger maintains reliability by providing robust impact resistance while reducing device complexity through consolidation of functions.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If separate centralizing and locking systems are used, then the locking function is provided, but the assembly process becomes time-consuming and complex

Engineering Contradiction:
Improveassembly easeVSAvoidassembly time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

By combining the centralizing and locking systems into a single integrated component, the patent enables assembly of both functions simultaneously. The unified structure with integrated pins and springs eliminates multiple assembly steps, reducing assembly time and simplifying the manufacturing process while maintaining the effectiveness of both centralizing and locking functions.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If multiple separate locking components are used, then the locking function is achieved, but the production costs increase

Engineering Contradiction:
Improveproduction costVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent reduces production costs by consolidating multiple separate components (centralizing pins, locking pins, springs) into a single integrated locking system. This merger reduces the total number of parts that need to be manufactured, inventoried, and assembled, thereby lowering production costs while maintaining the necessary functionality through the unified design.

Inventive Principle:
Principle #5Merging (Combining)

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 integrated spring system improves the robustness and durability of the locking mechanism, reducing assembly time and costs while ensuring secure closure and prolonged economic life of the folding cases.

Implementation Method 1

at least two springs (5) that are fixed onto the short side (1) and protrude in the upward and downward direction from the locking bolt (14), and that reinforce its centralization through their coordinated movement
