Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic transmission shift cable securing structures are bulky, heavy, difficult to install, and prone to improper installation, leading to increased labor costs and risks of incomplete attachment.
Innovation Solution
A transmission shift cable clip comprising two segments with mounting wings and a bridge that encircles the conduit end-fitting connector, secured using fasteners to bosses on the transmission housing, providing a compact, lightweight, and easy-to-install solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal bracket with mating fastener and assortment of screws is used to secure the transmission shift cable, then the securing structure provides strong attachment, but the device becomes bulky, heavy, and difficult to install
Solution Approach 1:
The patent combines multiple separate components (metal bracket, mating fastener, assortment of screws) into a single integrated clip assembly that secures the transmission shift cable. This merging of components reduces the number of parts, simplifies installation, and decreases the overall size and weight while maintaining secure attachment capability.
Solution Approach 2:
The clip assembly serves multiple functions simultaneously: it secures the transmission shift cable, provides structural support, and facilitates easy installation through its integrated design. The single clip structure replaces multiple specialized components, making the securing mechanism both universal and multi-functional.
2Reliability
If multiple parts requiring proper alignment and attachment are used, then secure attachment is achieved, but installation time and labor costs increase
Solution Approach 1:
The clip assembly is pre-configured as an integrated unit with all necessary attachment features built-in. This preliminary preparation eliminates the need for complex alignment and attachment procedures during installation, allowing for quick and reliable securing of the transmission shift cable without requiring multiple separate assembly steps.
3Strength
If conventional securing structures with multiple components are used, then attachment strength is maintained, but the risk of incomplete attachment and improper installation increases
Solution Approach 1:
The integrated clip assembly design is self-explanatory and self-aligning, reducing the risk of improper installation. The single-piece construction with built-in attachment features guides the installer through the process naturally, minimizing the possibility of incomplete attachment or incorrect assembly that can occur with multiple separate components requiring precise alignment.
