Through-Wall Donation Canister With Grate Drainage and Padlock Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collection canisters lack an effective design for through-wall applications in drive-thru settings, failing to provide an efficient and durable solution for collecting donations while managing moisture and potential jamming issues.
Innovation Solution
A through-wall collection canister comprising an outer component with a polymeric material, an inner component, and a donation container, featuring a donation passageway with a grate section for liquid drainage and a locking mechanism with padlock security, allowing easy disassembly for unjamming, and a design that deflects water from entering the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a through-wall collection canister is designed for drive-thru applications, then donation collection efficiency is improved, but moisture management and jamming issues arise
Solution Approach 1:
The collection canister is divided into multiple components: an outer shell, an inner container, a grate section, and a locking mechanism. This segmentation allows the grate section to manage moisture separately while the inner container collects donations, preventing jamming by allowing liquid to pass through the grate while retaining solid donations.
Solution Approach 2:
The grate section acts as an intermediary element between the donation opening and the collection container. It mediates the passage of materials by allowing liquids to drain through while blocking solids, thus managing moisture without causing jamming in the collection area.
2Reliability
If a secure locking mechanism is added to prevent theft, then security is improved, but device complexity increases
Solution Approach 1:
The locking mechanism uses movable locking bars that can shift between locked and unlocked positions. This dynamic design provides security when needed while allowing easy access when authorized, balancing security requirements with operational simplicity without requiring complex multi-step locking procedures.
3Ease of manufacture
If the canister is designed as a single integrated unit, then manufacturing is simplified, but maintenance and unjamming become difficult
Solution Approach 1:
The canister is constructed as an assembly of separate components (outer shell, inner container, grate section, locking bars) that can be manufactured independently and then assembled. This segmentation enables easy maintenance by allowing the grate section to be removed and cleaned separately, and the inner container to be accessed for unjamming without disassembling the entire structure.
4Reliability
If water deflection features are added to prevent water entry, then protection is improved, but device complexity increases
Solution Approach 1:
The deflection features utilize the vertical dimension by positioning the opening at the top of the outer shell and incorporating an overhead support structure. This dimensional arrangement allows water to naturally drain away from the opening due to gravity, providing water protection without requiring complex mechanical deflection mechanisms.

AI summary
There is an outer component and an inner component and a donation container. The outer component has a donation passageway with a grate section for passing liquid to the bottom of the device. There is a donation container which is locked in position with a pair of locking bars, secured with a padlock. There is a donation container frame which may be taken apart to removed jammed material from the donation passageway and donation container.
