Partially Detachable Belt Loop for Carrying Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses carrying cases worn on a belt are unstable, difficult to operate with one hand, and have inconvenient attachment and detachment processes, particularly the carabiner type which swings and wobbles, and the clip-on type which is slippery and time-consuming.
Innovation Solution
A carrying case with a movable flap and partially-detachable loop portions that can be securely attached and detached using fastening means like buttons or Velcro, allowing for easy one-handed operation and stable attachment to a belt, preventing the case from sliding or swinging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a carabiner type attachment is used, then the carrying case can be easily attached to the belt, but it swings and wobbles while moving and is not stabilized
Solution Approach 1:
The loop portion is designed to be flexible and adaptable, allowing it to conform to the belt shape and movement dynamics. The loop can deform and adjust during motion, maintaining stable attachment while accommodating the dynamic conditions of wearing the case during activities like jogging or climbing.
2Ease of operation
If a clip-on belt type is used, then the carrying case can be attached to the belt, but it is slippery and slides easily
Solution Approach 1:
The loop portion is made from a composite material that combines flexibility with high friction characteristics. This material composition allows the loop to grip the belt firmly, preventing sliding while maintaining ease of attachment and detachment.
3Stability of the object's composition
If a fixed loop on belt type is used, then the carrying case can be attached to the belt, but it requires a burdensome process including removing the belt from the pants, taking off case from the belt, and then putting the belt back on the pants
Solution Approach 1:
The attachment system is segmented into two independent parts: the loop portion attached to the case and the belt loop. This segmentation allows the loop to remain on the case while the belt can be independently adjusted or removed, enabling easy attachment and detachment without the burdensome process of removing the entire belt from the pants.
4Adaptability or versatility
If the loop portion is made flexible, then it can adapt to belt movement, but it may deform or lose shape
Solution Approach 1:
The loop portion utilizes a composite material that provides both flexibility for adapting to belt movement and sufficient structural integrity to maintain its shape. This material composition allows the loop to deform elastically during attachment and movement while returning to its original shape, preventing permanent deformation.

AI summary
A carrying case including a main body housing providing a storage space, an opening to the storage space, a movable part or flap, a partially-detachable loop portion, and at least one fastening means. The partially-detachable loop portion has a first end that is fixedly-attached to the main body housing, and a second end that is attachable/detachable to the main body housing by the fastening means. In a fully-attached state, the fastening means holds the second end of the partially-detachable loop portion to an outer surface of the main body housing until the at least one fastening means is released, the releasing allowing a partially-detachable loop portion to move to a partially-attached state where the second end freely moves.
