Foldable Backpack Supporting Bar for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing backpack supporting bars are inflexible, making it difficult to fold and store the backpack, leading to increased storage volume and transportation costs, and are inconvenient to mount or remove.
Innovation Solution
A backpack supporting bar with two connected sub-bars that can fold into an S-shaped structure, allowing for easy mounting and removal, and a detachable design that accommodates within a strip-shaped bag for reduced storage volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a long integrated supporting bar is used, then the supporting stability is improved, but the backpack cannot be folded and storage volume increases
Solution Approach 1:
The supporting bar is divided into multiple sections that can be folded relative to each other. Each section maintains structural integrity while allowing the overall bar to compact into a smaller volume when not in use, resolving the contradiction between maintaining supporting stability and reducing storage volume.
Solution Approach 2:
The supporting bar transitions from a static integrated structure to a dynamic foldable structure. The bar can extend to its full length for supporting stability during use, and fold to a compact configuration for reduced storage volume when not in use, adapting its state based on operational requirements.
2Reliability
If a long integrated supporting bar is used, then the supporting function is maintained, but mounting and removal becomes inconvenient
Solution Approach 1:
The supporting bar is segmented into multiple sections with connection mechanisms that allow easy assembly and disassembly. This segmentation enables convenient mounting and removal while maintaining the full-length supporting function when sections are assembled together.
Solution Approach 2:
The supporting bar incorporates movable connection joints between sections that allow for easy assembly and disassembly operations. These dynamic connections enable the bar to be quickly mounted and removed while maintaining structural integrity and supporting function during use.
3Volume of moving object
If a foldable supporting bar is used, then storage volume is reduced, but the supporting stability may be compromised
Solution Approach 1:
The supporting bar is divided into sections with connection mechanisms designed to maintain structural stability when assembled. The segmentation allows compact storage when folded while ensuring that the connected sections form a stable supporting structure when extended, preventing compromise of supporting stability.
Solution Approach 2:
The foldable supporting bar uses dynamic connection mechanisms that provide stability during the supporting function when extended, while allowing compact folding for reduced storage volume. The connection joints are designed to be rigid during use for stability, yet movable for compact storage, resolving the contradiction between storage volume and supporting stability.
