Rotating Sidewall Packing Box for Adjustable Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing boxes with fixed accommodation spaces can cause inconvenience when removing contents, as they may be either too small or too large, leading to damage during transport due to excessive shaking.
Innovation Solution
A packing box design featuring a rectangular bottom member and four sidewall members, where two pairs of sidewall members are fixed and rotating, allowing the rotating sidewall members to be inclined and covered by a sliding member to adjust the space, enabling easy expansion and contraction of the accommodation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the accommodation space is made larger to facilitate removing contents, then ease of operation is improved, but the contents may be excessively shaken during transport resulting in damage
Solution Approach 1:
The sidewall members are designed to be rotatable relative to the bottom member, allowing the accommodation space to dynamically adjust between expanded and contracted states. This enables the space to be enlarged when accessing contents and reduced during transport to minimize shaking damage.
Solution Approach 2:
The volume and shape parameters of the accommodation space are made changeable through the rotatable sidewall mechanism. The space can be transformed from a compact configuration during transport to an expanded configuration when contents need to be accessed, adapting to different operational requirements.
2Reliability
If the accommodation space is made smaller to reduce shaking during transport, then reliability is improved, but ease of removing contents deteriorates
Solution Approach 1:
The rotatable sidewall members enable the accommodation space to switch between contracted and expanded states. During transport, the contracted state provides reliability and protection, while when needed, the space can be expanded to improve ease of removing contents.
Solution Approach 2:
The accommodation space alternates between contracted and expanded states depending on the operational phase. It is contracted during transport for protection and expanded during content access for ease of operation, creating a periodic cycle of state changes.
3Device complexity
If a fixed size accommodation space is used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The sidewall members are designed with rotational capability, transforming the fixed structure into a dynamic one. This allows the same simple structure to adapt to different volume requirements without adding significant complexity to the overall design.
Solution Approach 2:
The sidewalls are divided into rotatable segments that can independently change position. This segmentation allows the accommodation space to be divided and reconfigured, providing adaptability while maintaining relative structural simplicity through modular design.

AI summary
Disclosed herein is a packing box in which the size and shape of an accommodation space are easily changeable to ensure convenient use of the contents. The packing box includes a rectangular bottom member and four sidewall members adapted to be erected at an outer perimeter of the bottom member, thereby defining an accommodation space having an open top. The sidewall members are divided into a pair of fixed sidewall members disposed facing each other to be vertically erected and fixed, and a pair of rotating sidewall members disposed facing each other between the fixed sidewall members to be inclined to an outside of the bottom member with respect to a vertical position thereof. The packing box includes at least one covering member to cover a gap between the fixed sidewall member and the rotating sidewall member when the rotating sidewalls are inclined.
