Dual-Wall Box Structure for Shock Protection and Accessory Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boxes fail to effectively protect articles from shocks and securely store accessories like spare parts, warranties, and instruction manuals.
Innovation Solution
A box design with a storage section surrounded by an inner and outer circumferential wall, a wall top plate connected via creases, and a lid section that can be opened to access accessories, featuring a side plate to prevent opening and a gap between walls to absorb shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple box structure is used to reduce manufacturing cost, then manufacturing cost is reduced, but the ability to protect articles from shock and store accessories is insufficient
Solution Approach 1:
The box is divided into an inner circumferential wall section and an outer circumferential wall section, creating a multi-layer structure. This segmentation allows the box to provide both shock protection (through the gap between walls) and accessory storage (through the space created by the segmented structure), while still being formed from a single flat plate material for cost-effective manufacturing.
Solution Approach 2:
The inner circumferential wall section is nested within the outer circumferential wall section, creating a concentric multi-layer structure. This nesting approach maximizes the protective and storage functionality within the box structure without significantly increasing manufacturing complexity, as both walls are formed from the same flat plate material through bending.
2Ease of manufacture
If the box structure is simplified to reduce cost, then manufacturing cost is reduced, but accessories cannot be securely stored
Solution Approach 1:
The box structure is segmented into inner and outer wall sections that create distinct functional zones. The space between these segmented walls provides a dedicated accessory storage area, enabling the box to hold both main articles and accessories securely while maintaining cost-effective single-material construction.
3Ease of manufacture
If a single wall structure is used, then manufacturing is simpler, but articles cannot be protected from shock
Solution Approach 1:
The wall structure is segmented into an inner circumferential wall section and an outer circumferential wall section with a gap between them. This segmentation creates a shock-absorbing space that protects articles from impact, while the entire structure remains manufacturable from a single flat plate through bending operations.
Solution Approach 2:
The gap between the inner and outer circumferential wall sections serves as a pre-configured cushioning space. This space is built into the structure beforehand to absorb shock and protect articles from impact, eliminating the need for additional cushioning materials while maintaining manufacturing simplicity.
4Device complexity
If the box has only a storage space for articles, then the structure is simpler, but accessories have no storage place
Solution Approach 1:
The box structure is segmented into functional zones using the inner and outer circumferential wall sections. This segmentation naturally creates distinct spaces: one for storing main articles and another (the gap between walls) for storing accessories, providing versatile storage functionality without requiring additional complex structural elements.
Solution Approach 2:
The space between the inner and outer circumferential wall sections serves multiple functions: it provides shock absorption for the articles while simultaneously serving as a storage compartment for accessories. This multi-functionality is achieved through the universal application of the segmented wall structure throughout the box.

AI summary
Provided is a box that can protect articles stored inside the box from a shock and can secure a storage place for accessories. A storage section of a box (1) has an inner circumferential wall section (11) that surrounds a storage space (S1), an outer circumferential wall section (12) that surrounds the inner circumferential wall section and forms a gap with the inner circumferential wall section, and a wall top plate section (13) that is connected to an upper end of the inner circumferential wall section and an upper end of the outer circumferential wall section via creases. A rear outer wall section (12B) of the outer circumferential wall section can be opened and closed to the outside about a crease with the wall top plate section in a state in which a lid section is opened. A side plate section (23) of the lid section (20) covers the outer surface of the rear outer wall section in a state in which the lid section is closed.
