Jobsite Box Keyless Entry for Lost-Key Access Delays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jobsite boxes require conventional keys for access, leading to delays, resource waste, and security risks due to key loss or misplacement, especially when relying on a single foreman for access.
Innovation Solution
A jobsite box with a keyless entry system using a controller, key pad, and actuators that can be unlocked via a code, Bluetooth, or Wi-Fi, with a backup key lock for emergencies, allowing remote access and code changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional keys are used for jobsite box access, then workers can access materials, but delays and resource waste occur when keys are lost or misplaced
Solution Approach 1:
The patent replaces the mechanical key-lock system with an electronic keypad and controller system. The keypad accepts numeric codes that are processed by a controller to trigger the locking mechanism, eliminating the need for physical keys and thereby preventing delays associated with key loss or misplacement.
Solution Approach 2:
The patent changes the access parameter from physical key insertion to numeric code entry. The controller compares the entered code against stored codes and activates the locking mechanism accordingly, transforming the access method from mechanical to electronic parameter verification.
2Reliability
If the foreman alone holds the keys, then key replacement cost is reduced, but the foreman must be present for access
Solution Approach 1:
The patent implements multiple access methods including keypad code entry, RFID cards, and remote wireless access. This allows various users to access the jobsite box independently without requiring the foreman's physical presence, while the foreman retains administrative control through code management and remote access capabilities.
Solution Approach 2:
The patent introduces a wireless communication intermediary (such as a mobile phone or remote device) that allows the foreman to unlock the jobsite box from a distance. The wireless signal acts as a mediator between the foreman and the locking mechanism, eliminating the need for physical presence while maintaining security control.
3Ease of operation
If multiple key sets are distributed to workers, then access is convenient, but key loss requires replacement of the entire locking system
Solution Approach 1:
The patent allows the foreman to generate multiple access codes or RFID cards without any physical replacement of the locking mechanism. Each worker receives a copied access credential (code or card) that can be independently managed, eliminating the need to replace the entire locking system when access credentials need to be updated or revoked.
4Ease of operation
If a keypad and controller system is implemented, then keyless access is enabled, but the device complexity increases
Solution Approach 1:
The patent merges the keypad, controller, locking mechanism, and power supply into a single integrated jobsite box unit. This consolidation simplifies installation and maintenance compared to separate distributed systems, as all electronic components are housed together and powered by a single battery compartment within the box.

AI summary
A jobsite box includes a body, the body having an interior, an exterior, and a lid, a key pad positioned on the exterior of the body, the key pad being in communication with a controller positioned on the body, a locking mechanism connected to the body, the locking mechanism being configured to lock and unlock the jobsite box, a battery positioned in the interior of the body, the battery configured to power the locking mechanism. The controller is configured to lock or unlock the locking mechanism when a predetermined code is entered into the key pad.
