Solution Overview

Problem

Existing battery holders struggle to stably hold battery units due to misalignment, requiring cumbersome adjustments, and lack efficient mechanisms for secure positioning and easy removal.

Innovation Solution

A battery holder design featuring a first base with a restriction portion and a holding portion that allows for precise positioning of the battery unit, utilizing protrusions and recesses for secure engagement and easy removal, with additional supports and a second base for enhanced stability and cable management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the battery unit and battery holder are positioned far from each other, then the battery holder cannot stably hold the battery unit, but burdensome adjustments are required to position them properly

Engineering Contradiction:

Improvestability of holdingVSAvoidpositioning adjustment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The first restriction portion is pre-formed on the first base at a specific position and orientation. When the battery unit is inserted, this pre-formed restriction portion automatically guides and positions the battery unit correctly, eliminating the need for cumbersome adjustments during assembly

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The first restriction portion acts as an intermediary element between the first base and the battery unit. It mediates the positioning relationship by physically restricting relative movement in the first direction, enabling stable holding without requiring precise manual alignment

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If a complex positioning mechanism is used to ensure proper positioning, then positioning accuracy improves, but device complexity increases

Engineering Contradiction:

Improvepositioning accuracyVSAvoidstructure complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The positioning function is segmented into distinct elements: the first restriction portion for restricting movement in the first direction, and the first portion for positioning in the orthogonal direction. This segmentation allows each element to perform its specific function with a simple structure, avoiding the need for a complex integrated positioning mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of using a complex active positioning mechanism, the invention uses passive geometric constraints through protrusions and recesses. The battery unit's side wall features recesses that receive protrusions on the battery holder, creating precise positioning through complementary shapes rather than active adjustment mechanisms

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A battery holder includes a first base, a first restriction portion and a holding portion. The first base is opposed to one end of a battery unit in a first direction in the state in which the battery unit is located at a holding position. The first restriction portion is configured to restrict relative movement of the battery unit and the first base in the first direction. The holding portion is movable to a first position, at which the battery unit contacts a held portion of the battery unit, and a second position, at which the holding portion is separated from the held portion.
