Self-locking Lug Protector with Sliding Lock for Wiring Harness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wiring harness lug protection methods are inadequate as they are not mechanically secured, risk foreign object debris, are bulky, interfere with installation, and do not allow for visual orientation identification, requiring two hands for application and removal, and are time-consuming.
Innovation Solution
A wiring protection device with a main body and sliding locking members that securely engage and disengage the lug, allowing single-hand operation, providing visual orientation indicators, and being compact enough for easy handling and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If bubble wrap and rubber band are used to protect the lug, then the lug is protected from damage, but the protection is not mechanically secured and risks foreign object debris
Solution Approach 1:
The protection device is divided into a main body and a separate locking member. The locking member can be engaged or disengaged independently from the main body, allowing the lug to be securely held during installation while enabling easy removal when needed. This segmentation resolves the contradiction by providing both secure attachment (preventing FOD) and controlled release capability.
2Object-affected harmful factors
If bubble wrap and rubber band are used to protect the lug, then the lug is protected from damage, but the protection is bulky and interferes with installation
Solution Approach 1:
The locking member is received within a cavity in the main body when not in use, similar to a nested doll structure. This allows the protection device to maintain a compact form factor while still providing secure protection when the locking member is engaged, resolving the contradiction between protection effectiveness and bulkiness.
3Object-affected harmful factors
If bubble wrap and rubber band are used to protect the lug, then the lug is protected from damage, but it takes significant time to apply and remove the protection
Solution Approach 1:
The locking member is designed to be manually operable by a single hand, allowing the user to quickly engage and disengage the protection device without requiring assistance or complex manipulation. This self-service design significantly reduces the time needed to apply and remove protection compared to traditional bubble wrap methods.
4Object-affected harmful factors
If bubble wrap and rubber band are used to protect the lug, then the lug is protected from damage, but the user is required to utilize both hands to apply and remove the protection
Solution Approach 1:
The locking member is designed with a simple engagement mechanism that can be operated by a single hand. The user can easily slide the locking member into the engaged position to secure the lug or disengage it for removal, eliminating the need for two-handed operation and improving ease of use during installation tasks.

AI summary
A wiring protection device includes a main body that defines a cavity for receipt of an associated lug of an associated wiring harness. The wiring protection device also includes a first locking member that is slidably received in the main body to define a lock, position that engages the associated lug to prevent removal of the associated lug from the main body and an unlock position that does not engage the associated lug and allows removal and installation of the associated lug out of and into the main body.
