Strapless Paintball Pod Holder Using Elastic Tunnel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current paintball pod packs with retention straps are difficult to use, require assistance for loading and unloading, and suffer from misalignment issues that lead to pod slippage and contamination, wasting time and causing costly losses during games.
Innovation Solution
A retention tunnel system using a semi-rigid stabilizing plate and elastic band, forming a saddle-shaped, hyperbolic paraboloid structure that securely holds paintball pods without the need for straps, allowing one-handed removal and reinsertion and maintaining holding force through repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hook-and-loop retention straps are used to secure pods in slots, then pods can be held securely during physical activity, but the straps become entangled and misaligned requiring two hands or assistance to realign
Solution Approach 1:
The invention extracts and eliminates the retention strap component entirely from the pod holder system. Instead of using hook-and-loop straps that require alignment and manual adjustment, the design relies on the structural geometry of the pod holder slots and pods themselves to provide retention through friction and normal force, enabling one-handed operation without strap entanglement issues
Solution Approach 2:
The pod holder structure is designed to be self-retaining through its geometric configuration. The slot dimensions and pod dimensions are matched so that the pod naturally maintains frictional contact with the slot walls during normal use, eliminating the need for external retention mechanisms that require manual intervention
2Reliability
If retention straps are used to hold pods, then pods are secured in slots, but the straps wear and fray over time reducing holding force
Solution Approach 1:
The invention removes the retention strap component from the system entirely, eliminating the wear and friction issues associated with hook-and-loop fasteners. The retention function is achieved through the permanent structural geometry of the pod holder slots rather than consumable straps that degrade over time
Solution Approach 2:
The design eliminates disposable or degradable components (straps) in favor of a permanent structural solution. The pod holder structure is designed to maintain its retention properties indefinitely through its geometric configuration rather than relying on materials that wear out
3Ease of operation
If elastic bands are used in pod slots, then pods can be removed easily, but empty pods cannot be readily replaced during play
Solution Approach 1:
The pod holder design incorporates localized friction zones within the slot geometry that provide differential retention characteristics. The slot structure creates natural friction points that allow easy removal of filled pods while providing sufficient resistance to prevent accidental loss of empty pods during quick replacement operations
4Ease of operation
If semi-rigid tunnel slots are used, then pods can be removed and replaced with one hand, but retention straps are still required to hold pods securely
Solution Approach 1:
The invention eliminates the retention strap subsystem while maintaining one-handed operation capability. The semi-rigid tunnel slot geometry is designed so that the pod's own weight and the slot's friction characteristics provide sufficient retention without requiring additional straps or fastening mechanisms
Solution Approach 2:
The retention function previously separated into distinct straps is merged into the structural geometry of the slot itself. The slot dimensions, angle, and surface characteristics are integrated to provide both the structural support and retention forces in a unified design
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure, one-handed loading and unloading of paintball pods, preventing slippage and contamination, and reducing operational time, while maintaining holding force over repeated use without the entanglement and wear issues of traditional strap-based systems.
Implementation Method 1
an elastic band having four sides and stretchable in a stretch plane... whereby said tension from said elastic band causes said stabilizing plate to bend and form a retention tunnel exhibiting elastic, radial, compression forces on a paintball pod inserted into said tunnel
Implementation Method 2
said stabilizing plate is attached to said elastic band on either side of said band transverse to said stretch axis whereby said tension from said elastic band causes said stabilizing plate to bend and form a retention tunnel

AI summary
The present invention provides a strapless holder that securely supports a generally cylindrical object, such as a paintball pod, within the retention tunnel by an elastic band that is curved to form at least a portion of a saddle-shaped, hyperbolic, paraboloid within the retention tunnel. Also provided is a method for using a retention strap-free holder for paintball pods for fast access to replenishment paintball pods.
