Pivoting Carrying Case with Movable Strap Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carrying cases do not allow easy front access while being worn, limiting user convenience and accessibility of contents.
Innovation Solution
A carrying case design featuring a housing with a guide member along the bottom, a primary carrying strap with a movable end, and an adjustable stop cord, enabling the case to be swung to the front for access, along with a lid and reinforcement frames for structural support and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the carrying case is designed to be worn on the back, then it provides stable carrying position, but it prevents easy front access to contents
Solution Approach 1:
The carrying case incorporates a movable strap system that allows the case to be dynamically repositioned from a static back-wearing position to a front-accessible position. The strap can be moved along a guide member to enable the case to swing between different configurations, providing front access while maintaining the worn state.
Solution Approach 2:
The strap is divided into segments with a movable connection point that can travel along the guide member. This segmentation allows the strap to be repositioned independently, enabling the carrying case to be accessed from the front while remaining worn on the back.
2Adaptability or versatility
If the strap is made fixed for stable wearing, then it ensures secure positioning, but it prevents reconfiguration for front access
Solution Approach 1:
The strap system transitions from a fixed state to a dynamic reconfigurable state. The movable connection point on the strap allows it to be repositioned along the guide member, enabling adaptation between back-wearing and front-access configurations while maintaining secure positioning in each state.
Solution Approach 2:
The guide member and stop cord are pre-configured to define the permissible movement range and positions of the strap. This preliminary arrangement enables reliable reconfiguration at specific predetermined positions without compromising positioning stability.
3Strength
If the carrying case structure is simplified, then it reduces manufacturing complexity, but it compromises structural support and stability
Solution Approach 1:
Instead of uniformly strengthening the entire housing, reinforcement frames are strategically placed at specific locations where structural support is most needed. This localized reinforcement approach provides necessary strength while minimizing overall structural complexity and material usage.

AI summary
A carrying case comprises a housing having a top, a bottom, a front, and a rear. There are sides extending between the front and the rear of the housing. There is a guide member extending along the bottom of the housing. The carrying case further comprises a carrying strap having a first end and a second end. The first end of the carrying strap is connected near the top of the housing and the second end of the carrying strap is coupled to the guide member. The second end of the carrying strap is movable along the guide member to allow the carrying case to be moved between different configurations.
